Characteristics of prematurity VI. interventions of prematurity VII. Diagnostic interventions VIII. Problems related to Gestational weight TIFICATION OF AT-RISK NEWBORN I. I. IDENTIFICATION OF AT-RISK NEWBORN ● High- risk neonate is a newborn, regardless of gestational age or birth weight, who has a greaterthan-average chance of morbidity or mortality because of conditions or circumstances superimposed on the normal course of events associated with birth and the adjustments to extrauterine existence. B. Small for date (SFD) or Small for Gestational Age (SGA) o o regardless - SGA, LGA, premature, postmature Conditions and circumstances: if AGA inside and swallowed meconium - possible meconium o superimposed / adjustment to extrauterine something happened during the delivery process RECAP: o Normal weight – 2.5 kg - 3.5 kg o Term – 38 - 42 weeks o Premature – 23 - 37 weeks ● A. Appropriate for gestational age (AGA) infant ● ● ● The – risk period encompasses human growth & development from the time of viability, the gestational age at which survival outside the uterus is believed to be possible, or as early as 23 weeks of gestation up to 28 weeks following threats to life & health that occur. o premature may have jaundice. o Solution: phototherapy / exposure to sunlight II. CLASSIFICATION OF HIGH-RISK INFANTS BASED ON GESTATIONAL AGE ● ● if the birth weight is BELOW the 10th percentile on intrauterine growth curve for that age or birth weight less than expected for the specific gestational age. The infant maybe born preterm (before38th week gestation), term (between weeks 38 & 42), or post term (past 42 weeks). Ex. 38 weeks’ gestation who weighs 5 lbs. SGA infants are small for their age because they have experienced INTRAUTERINE GROWTH RETARDATION (IUGR) - or restriction or failed to grow at the expected rate in utero. o o o o Post term Term Preterm Abortion (past 42 weeks) (38 – 42 weeks) (20 – 37 weeks) (less than 20 weeks) CAUSES: 1. an infant whose weight falls BETWEEN the 10th& 90th percentile on intrauterine growth curves or birth weight expected for the gestational age. Ex. 34th week o Weight should be proportion sa gestational age o 2 years old ang ?2 2. Mothers nutrition during pregnancy plays a major role in fetal growth outcome & lack of adequate nutrition maybe a major contributor to IUGR & most common cause of IUGR is placental anomaly, either: ● the placenta did not obtain sufficient nutrients from the uterine arteries ● it was insufficient at transporting nutrients to the fetus. Placental damage such as partial placental separation with bleeding limits placental function. ● painful bleeding (abruptia placenta) 1 ● 3. 4. 5. placenta previa - painless bleeding; can’t be felt by the mother ● not functioning at full capacity Women with systemic diseases that decrease blood flow to the placenta as severe diabetes mellitus or pregnancy – induced hypertension. Mothers who smoke heavily or use narcotics. Affects the growth of the baby. ● important to ask in history taking Placental supply of nutrients is adequate, but the infant can’t use them - intrauterine infections of rubella or toxoplasmosis. ASSESSMENT ● Prenatal Assessment- maybe detected in the utero by taking the fundal height (Leopold’s Maneuver) during pregnancy. ● How to take fundic height: from pubic bone to the top of the uterus (specifically: fundus) ● Do NOT take with contractions (because it increases measurement) ● Sonogram can demonstrate the decreased size, biophysical profile including a non-stress test, placental grading ultrasound examination can provide placental function. APPEARANCE 1) Below average in weight, length, & head circumference. 2) Skin is dry, little fat ● Wasted appearance 3) Small liver, which may cause difficulty regulating glucose, protein, & bilirubin levels. 4) Poor skin turgor & generally appears to have a large head because the rest of the body is so small. 5) Skull sutures may be widely separated from lack of normal bone growth. 6) Hair is dull & lusterless 7) Abdomen may be sunken. ● (ideal: globullar) 8) The cord often appears dry & maybe stained yellow. 9) Better neurologic responses, sole creases, & ear cartilage expected for a baby of that weight. 10) Skull may be firmer & the infant may seem unusually alert & active for that weight. ● check active: apgar, loud vigorous cry LABORATORY FINDINGS ● High hematocrit level – due to lack of fluid in the utero. ● Polycythemia – increase in RBC due to a state of anoxia during intrauterine life. NO OXYGEN ● Acrocyanosis – results due to blood viscosity & is difficult to circulate thick blood. (HEEL PRICK = VERY THICK) COMMON PROBLEM ● ● ● 1. HYPOGLYCEMIA decreased glycogen stores - decreased blood glucose or level below 40mg/dL- IVF to sustain blood sugar until able to suck vigorously enough to take oral feedings. Normal: 40 mg/dL above diabetic mothers -> first order is to take blood sugar by heel pricking to check blood sugar 2. BIRTH ASPHYXIA due to under-developed chest muscles & risk for developing meconium aspiration syndrome due to anoxia during labor. o (no oxygen going to the baby because entrapped by meconium, baby blue APGAR: 0-3) ● Fetal hypoxia causes reflex relaxation of the anal sphincter & increased intestinal movement. ● With gasping the fetus draws meconium discharged into the amniotic fluid into the Tracheobronchial tree. As a foreign substance it blocks airflow into the alveoli leading to hypoxemia, acidosis & hypercapnia. ALVEOLI DOES NOT EXPAND Nursing Diagnosis ● Ineffective breathing pattern related to underdeveloped body systems at birth. Outcome Identification ● NB will initiate & maintain respirations at birth. Outcome Evaluation ● NB maintains normal respirations at a rate of 30 -60 breaths/ min. after resuscitation at birth. 3. Less able to control body temperature than a normal newborn because they lack subcutaneous fat. Controlled environment is essential to keep the infant’s body temperature in neutral zone. ● immature hypothalamus and lack of brown fat ① Nursing Diagnosis ● Risk for ineffective thermoregulation related to lack of subcutaneous fat. Outcome Identification ● NB will maintain body temperature within normal limits. Outcome Evaluation ● Infant’s temp is maintained at 36.5C of 97.8F ② Nursing Diagnosis ● Risk for impaired parenting related to child’s high-risk status & possible cognitive impairment from lack of nutrients in utero. (may be due to CS and stitches) Outcome Identification ● Parents will demonstrate beginning bonding behavior with infant while in the hospital Outcome Evaluation ● Parents express interest in infants & ask questions about what the child’s care needs will be at home. Intervention ● Adequate stimulation ● Provide toys suitable for their chronological age 2 ● Nursing Interventions 1. Care of SGA infant is similar in many instances to care of preterm infant. 2. Tailor high-level nursing care to meet specific needs of infant with regard to functioning of all body systems, psychologic growth & development, parental support & teaching, & prevention of complications. C. Large for gestational age (LGA termed macrosomia) ● ● an infant whose birth weight falls ABOVE the 90th percentile or birth weight more than expected on an intrauterine growth chart for the specific gestational age. Ex. Baby born on the 30th week of gestation weighing 5 lbs. on intrauterine growth charts. CS may be necessary because of CPD (the biparietal diameter is closer to 10 cm than usual 9 cm) or shoulder dystocia (wide shoulders are unable to pass through the outlet of the pelvis. ASSESSMENT CRITERIA FOR AN LGA INFANT 1) Skin color for ecchymosis, jaundice, & erythema. 2) Motion of extremities on spontaneous movement & in response to a Moro’s reflex to detect fracture. 3) Symmetry of the anterior chest or unilateral lack of movement to detect diaphragmatic 4) paralysis from edema of the phrenic nerve. 5) Eyes for evidence of unresponsive or dilated pupils, vomiting, bulging fontanelles, & high-pitched cry suggestive of increased intracranial pressure. 6) Activities such as jitteriness, lethargy, & uncoordinated eye movement that suggest seizure activity. ASSESSMENT / DIAGNOSTIC TEST 1. A sonogram to confirm the suspicion 2. Non stress test to assess the placenta’s ability to sustain the large fetus during labor 3. Lung maturity may be assessed by amniocentesis. 4. Recognized during labor when infant can pass through the pelvic brim. APPEARANCE: 1. At birth show immature reflexes & low scores on gestational age examinations in relation to his size. 2. May have extensive bruising or a birth injury such as broken clavicle or Erb Duchenne paralysis from trauma to the cervical nerves if born vaginally. 3. Head is large due to pressure at birth prone to caput succedaneum, cephal- hematoma, or molding. CAUSES: 1. 2. 3. 4. 5. Overproduction of growth hormone in utero in diabetic mothers with poorly controlled glucose levels. Multiparous women because with each succeeding pregnancy, babies tend to grow larger. o every pagbubuntis lumalaki yung weight ng baby Other conditions: Transposition of the great vessels o group of congenital heart defects Beckwith Syndrome - overgrowth disorder usually present at birth, characterized by increased risk of childhood cancer & certain congenital features. Congenital anomalies – omphalocele - Abnormal contents small & large intestines, stomach & liver, protrude through a hole in the abdominal wall. o Do not put the baby in the prone position, dryness causes rupture o by 4 gauze soaked with saline to moisten o if located at the back, prevent supine position ASSESSMENT Fetus is suspected LGA when the uterus is unusually large for the date of pregnancy. ● possible polyhydramnios: too much amniotic fluid Molding of the head 3 Cardiovascular Dysfunction ● ● o Heart rate should be observed. Cyanosis may be a sign of transposition of the great vessels, a serious heart anomaly. POLYCYTHEMIA – is caused by the infant’s systems attempting to fully oxygenate all the body tissues. HYPERBILIRUBINEMIA – increased bilirubin level which may result from absorption of blood from bruising & polycythemia. HYPOGLYCEMIA – in the early hours of life because the infant uses up nutritional Stores readily to sustain his weight. If the mother has diabetes that is poorly controlled, the infant will have an increased blood glucose level in the utero, which causes the infant to produce elevated levels of insulin. At birth, the increased insulin will continue for up to 24 hours of life, causing rebound hypoglycemia. ① Nursing Diagnosis ● Ineffective breathing pattern related to possible birth trauma in large for-gestational age NB. Outcome Identification ● NB will initiate & maintain respirations at birth. Evaluation — NB initiates breathing at birth; maintains normal NB respiratory rate of 30-60 breaths / minute. ● Difficulty establishing respiration because of birth trauma. ● Increased intracranial pressure from birth of the larger-than usual head may lead to pressure on the respiratory center causing a decrease in respiratory function. ② Nursing Diagnosis ● Risk for imbalanced nutrition, less than body requirements related to additional nutrients needed to maintain weight & prevent hypoglycemia Outcome Identification ● Infants will ingest adequate fluid for growth during the neonatal period. Outcome Evaluation ● Infant’s weight follows percentile growth curve; skin turgor is good; specific gravity of urine is 1.003 to 1.030; serum glucose is above 40mg/dL. by heel prick ● As a rule, LGA infants need to be breastfed immediately to prevent hypoglycemia. (If cannot breastfeed Supplemental formula feedings after breast feeding to supply enough fluid & glucose for the larger than normal for the first few days. o Mother can also use breast pump, supplemental feedings must be prescribed because it is still not allowed for NB ③ Nursing Diagnosis ● Risk for impaired parenting related to high -risk status of large for gestational age infant. they can touch and talk as long as they follow the policy Outcome Identification ● Parents demonstrate adequate bonding behavior during the neonatal period. Outcome Evaluation ● Parents hold infant; speak of the child in positive terms, state accurately why infant needs to be observed closely during postnatal period. PROBLEMS RELATED TO MATURITY A. PREMATURE (PRETERM) INFANT an infant born before the end of 37 weeks of gestation, regardless of birth weight or born before the 38 week. Weight of less than 2500g (5 lb. 8 oz.) at birth. ● th B. PRETERM INFANTS born before term (before the beginning of the 38 week of pregnancy). ● th 4. 5. 6. 7. 8. Low birth weight (LBW) ● an infant whose birth weight is less 2500g, regardless of gestational age. Moderately Low Birth Weight infant (MLBW) ● an infant whose birth weight is 1501 to 2500g Very low birth weight (VLBW) ● an infant whose birth weight is 1000 to 1500g born before 30 weeks of pregnancy (3 lbs. & 5 oz.) Extremely Low Birth Weight infant (ELBW) ● an infant whose birth weight is 500 - 1000g (2 lbs. & 3 oz.) born at 27 weeks gestation or even younger. Minimum age of viability is 23 weeks gestation CLASSIFICATION 1. Late preterm - born between 34 & 37 weeks. 2. Early preterm - born between 24 & 34 weeks. 3. Post term - Infants born after the end of 42 weeks of pregnancy. CAUSES 1. Maternal factors: age, smoking, poor nutrition, placental problems, preeclampsia/ eclampsia. 2. Fetal factors: multiple pregnancy, infection, intrauterine growth retardation (IUGR). 3. Other: low socioeconomic status, early termination of pregnancies (mangyayari kung may condition ang nanay for ex: pre-eclampsia or may sakit sa puso), environmental exposure to harmful substances, iatrogenic causes, such as elective cesarean birth & inducement of labor according to dates rather than fetal maturity. FACTORS ASSOCIATED WITH PRETERM BIRTH 1. Low socio- economic level - no balanced diet o no money no care 2. Poor nutritional status 3. Lack of prenatal care 4. Multiple pregnancy 5. Prior previous early birth 6. Race (non- white higher incidence) 4 7. 8. 9. 10. 11. 12. 13. 14. 15. ▪ ▪ ▪ ▪ Cigarette smoking Age of the mother (highest incidence younger than age 20) Order of birth Closely spaced pregnancies (need of family planning, especially for CS) Abnormalities of the mother’s reproductive system, such as intrauterine septum Infections (especially UTI) Obstetric complications such as PROM or premature separation of placenta (premature rupture of membrane) o avoid ambulation, bedrest to prevent cord prolapsing Early induction of labor using oxytocin Elective cesarean birth o patient suggests, they want to do it on a specific date. CHARACTERISTICS Appearance - small & underdeveloped. The head is disproportionately large (3cm or more- greater than chest size). The skin is generally or usually ruddy because the infant has little subcutaneous fat beneath it; veins are easily noticeable; & a high degree of acrocyanosis may be present. Preterm neonate, 24-36 weeks, typically is covered with vernix caseosa. In very preterm newborns (less than 25 weeks’ gestation), vernix is absent because it is not formed this early in pregnancy. Lanugo is usually extensive, covering the back, forearms, forehead, & sides of the face, because this amount is present until late in pregnancy. Both anterior & posterior fontanelles are small. Few or no creases on the soles of the feet. anterior - diamond posterior - triangle The eyes are small, with varying degrees of myopia (nearsightedness) because of lack of eye globe depth. The cartilage of the ear is immature & allows the pinna to fall forward. The ears appear large in relation to the head. The level of the ears should be carefully inspected to rule out chromosomal abnormalities. o Pull the pinna backward and upward Neurologic function Neurologic function is difficult to evaluate. Sucking & swallowing is weak & immature, deep tendon reflexes such as Achilles tendon are markedly diminished. Cry is weak & highpitched. o To test for chromosomal abnormalities - outer canthus must be in level with the pinna. o mechanical ventilator, umbilical catheterization they can also put IV on umbilical cord. Head can also be used. Pre- term SGA Intensive Incubator Radiant Warmer Radiant Warmer with Mechanical Ventilator General activity is feebler & weaker; often assume frog-like position; Scarf sign - elbow passes the midline of the body. Square window - wrist at a 90 degrees angle CNS center for respiration is underdeveloped, which results in irregular breathing w/ short periods of apnea. O2 administered should never be more than 40% because it can lead to blindness due to retrolenthal fibroplasia, an overgrowth of retinal blood vessels causing blindness. o center for respiration: medulla oblongata o center for temperature control: hypothalamus Mechanical Ventilator 5 COMPONENTS OF NEUROMUSCULAR ASSESSMENT / BALLAD SCORE 1. 2. 3. 4. 5. 6. Posture Square window Arm recoil Popliteal angle Scarf sign Heel to ear POSTURE Assess posture for degree of flexion. Term - legs & arms are moderately Flexed at rest. Preterm - lesser degrees of flexion POPLITEAL ANGLE Term NB’S are less flexible, with about 90 degrees angle, Measure the popliteal angle by moving the foot gently toward the head until you meet resistance. Then measure the distance behind the knee in the popliteal area. Preterm – the leg straightens to 180 degrees angle. SQUARE WINDOW Assess square window by grasping the NB’s forearm & gently flexing the wrist toward the inner arm. Do NOT allow rotation of the wrist. Term the hand should touch the wrist resulting to 0-degree angle. Preterm - greater angles of flexion. The younger, the less flexibility of the wrist. SCARF SIGN Scarf sign by grasping the NB’s hand & attempting to cross the arm over the body at the neck. Arms of the Term NB meet resistance before crossing midline. Premature NB cross the elbow past midline. HEEL TO EAR ARM RECOIL Assess heel to ear by raising the NB’s heel towards his head in an attempt to bring the foot to ear. DON’T bring the NB’s buttocks off the examination surface. Stop when you meet resistance & measure the degree of extension of the leg. Preterm you’ll come close to touching the heel to the ear. Term - you’ll meet resistance almost immediately. Measure arm recoil by first flexing & holding both forearm for 5 sec. then extending the hands & arms fully at the NB’s side. Release the hands & allow the arms to recoil (return to flexion) Term full recoil to a position of flexion. Preterm less flexion 6 COMPONENTS OF PHYSICAL MATURITY 1. 2. 3. 4. 5. 6. Skin Lanugo Plantar surface Breast Eye/ear Genitals SKIN Skin ranges from translucent & friable in preterm. Post term - leathery, cracked to wrinkled. GENITALS Term - testes usually descend near term & rugae are visible on the scrotum. Palpate testes to determine if they have descended. & note the rugae. Premature - flat & smooth Female NB at term - labia majora are larger than the clitoris & the labia minora. Preterm have prominent clitoris & small labia minora. LANUGO MALE FEMALE Lanugo - very fine body hair. Extremely premature NB’s have none. Term NB’s have very little. Post term - nearly absent. PLANTAR SURFACE Term NB’s have creases over the entire plantar surface. Preterm - from absent to faint red markings. Hypospadia - below Epispadia - above Cryptorchidism - undescended testes Hypothalamus - center for temperature control Medulla Oblongata - center for respiration BREAST Inspect the breast to assess the size of the breast bud in millimeters & the development of the areola. Preterm NB’s lacked developed breast tissue. Term - have a raised to a full areola with breast buds that are 3 to 10 millimeters in diameter. EYE/EAR The eye/ear assessment is an analysis of the ear cartilage & shape of the pinna. Preterm – pinna is less curved. Term – well-curved pinna with firm cartilage. Ear recoil goes back quickly. Preterm eyes fused eyelids. CNS center for respiration is underdeveloped, which results in irregular breathing w/ short periods of apnea. O2 administered should never be more than 40% because it can lead to blindness due to retrolental fibroplasia,- an overgrowth of retinal blood vessels causing blindness. due to too much oxygen. POTENTIAL COMPLICATIONS (1) Anemia of Prematurity Cause: low levels of Vitamin E, less iron stores ● Develop normochromic, normocytic anemia. Blood cells may be fragmented or irregularly shaped. ● The reticulocyte count is low because bone marrow does not increase its production until approximately 32 weeks. ● Infants appear pale, lethargic & anorectic & fail to thrive. ● The fault appears to be immaturity of the hematopoietic system combined with destruction of RBC due to low levels of vitamin E, which normally protects RBC against oxidation. ● They have less iron stores (because transfer of iron stores from the mother to the baby also occurs during the last weeks of pregnancy) & smaller RBC mass (since cord was cut immediately after delivery). 7 Intervention: ● Blood transfusion, vitamin E & iron provided by preterm formula, administration of DNA recombinant erythropoietin. (2) Hyperbilirubinemia Cause: immaturity of the liver ● Kernicterus (staining of brain cells with bilirubin, causing irreversible brain damage or even death) or destruction of brain cells by invasion of indirect bilirubin. This invasion results from excessive breakdown of RBC. ● More prone because with acidosis that occurs from poor respiratory exchange, brain cells are susceptible to the effect of indirect bilirubin than normally. ● They have less serum albumin available to bind indirect bilirubin & therefore inactivate its effect. Because of this, kernicterus may occur at lower levels (as low as 12mg/ 100ml of indirect bilirubin) in these infants. Intervention: ● If jaundice occurs, phototherapy or exchange transfusion can be started to prevent excessively high indirect bilirubin levels. ○ Phototherapy - cover eyes, whole skin is exposed ○ exchange transfusion through umbilical catheterization - insert catheter in the artery of the baby -> insert 3 way stop-cock -> 5cc out and 5 cc in, using syringe until the pack of blood is finished. The blood that is out is put in the blood warmer. Monitor vital signs. (3) Persistent Patent Ductus Arteriosus Cause: Because preterm infants lack surfactant, their lungs are noncompliant. It is more difficult for them to move blood from the pulmonary artery into the lungs. ● This condition leads to pulmonary artery hypertension, which may interfere with closure of the ductus arteriosus. Intervention: ● Administer IV Therapy cautiously to avoid increasing blood pressure. Indomethacin may be administered to initiate closure of the patent ductus arteriosus. Through endotracheal tube. Diagnostic intervention: Cranial ultrasound done after the first few days of life to detect if hemorrhage has occurred. An infant’s prognosis is guarded until it can show that development in the infant is normal after an intracranial bleeding. PROBLEMS RELATED TO GESTATIONAL WEIGHT A. Low birth weight (LBW) ● Birth weight: 1500 to 2500 or less 2500g, regardless of gestational age. B. Moderately Low Birth Weight infant (MLBW) ● Birth weight : 1501 to 2500g C. Very low birth weight (VLBW) ● Birth weight : 1000 to 1500g ● born before 30 weeks of pregnancy (3 lbs. & 5 oz.) D. Extremely Low Birth Weight infant (ELBW) ● Birth weight : 500 - 1000g (2 lbs. & 3 oz.) ● born at 27 weeks gestation or even younger. E. Minimum age of viability is 23 weeks gestation Infants born after the 37th week are considered term. ● ● All such infants need neonatal intensive care from the moment of birth to give them their best chance of survival without neurologic effects. A lack of lung surfactant makes them extremely vulnerable to respiratory distress syndrome. OTHER POTENTIAL COMPLICATIONS 1. 2. 3. 4. RDS Apnea Retinopathy of prematurity Necrotizing enterocolitis (4) Periventricular/ Intraventricular hemorrhage Preterm infants are particularly prone to periventricular hemorrhage (bleeding into the tissue surrounding the ventricles) or intraventricular hemorrhage (bleeding into the ventricles). Cause: Preterm infants have fragile capillaries & immature cerebral vascular development their susceptibility. ● When there is rapid change in cerebral blood pressure, such as with hypoxia, IV infusion, ventilation, & pneumothorax, the capillaries rupture. The infant experiences brain anoxia beyond the rupture. Hydrocephalus may occur from bleeding into the aqueduct of Sylvius with resulting obstruction of the aqueduct. pneumothorax - air in the lungs. take anthropometric measurement, measure HC for baseline hydrocephalus may occur from bleeding, bulging fontanelles ● 8 Week 2: Preterm: Apnea and Nursing Diagnoses, Assessment, Interventions, Post-Maturity I.

Gavage Feeding C. Formula Feeding Ineffective Thermoregulation Risk for Infection Assessment Interventions Post Maturity Worsened by variety of factors: 1. Infection 2. Intracranial hemorrhage (within the skull) 3. Patent ductus arteriosus – PDA (abnormal opening between the aorta and the pulmonary artery) 4. suffix: mia = blood, xia = tissues THERAPEUTIC MANAGEMENT 1. Administer Methylxanthines: theophylline, or caffeine ● ● ● I. APNEA OF PREMATURITY Reason: baby was born prematurely and alveoli does not have surfactant. Atelectasis occurs. ● Is a common phenomenon in the preterm infant. Infants less than 33 weeks gestation & healthy infants less than 30 weeks of gestation. Resolves as the infant approaches 37 weeks gestation. (lung surfactant matures and becomes adequate) ● Apnea is a lapse of spontaneous breathing for 20 seconds or more, or shorter pauses accompanied by hypotonia, bradycardia or color change. o Hypotonia - lethargic or not alert o Bradycardia - slow heart rate o Color change - pale and cyanotic o Baby is nude/diaper, kept in supine position to check the breathing pattern. o NEVER ON PRONE POSITION 1. CLASSIFICATION ACCORDING TO ORIGIN Central apnea - an absence of diaphragmatic & other respiratory muscle function that causes a lack of respiratory effort & occurs when CNS does not transmit signals to the respiratory muscle. 2. Obstructive apnea - when air flow ceases because of upper airway obstruction, yet chest or abdominal wall movement is present. 3. Mixed apnea - a combination of central & obstructive apnea, & the most common form of apnea seen in preterm infants. PATHOPHYSIOLOGY ● Apnea of Prematurity reflects the immature & poorly refined neurologic & chemical respiratory control mechanisms in premature infants. These infants are NOT responsive to hypercarbia & hypoxemia, & their neurons have fewer dendritic associations than those of more mature infants. Respiratory reflexes are significantly less mature. ○ Hypercarbia: high CO2 ○ Hypoxemia: decreased O2 in blood ● Overall weakness of the thorax, diaphragm & upper airway may also contribute to apneic episodes. Apnea is characteristically observed during the period of REM sleep. ● aminophylline, Act as CNS stimulants to breathing. Observe symptoms of toxicity. Serum theophylline levels are determined by the infection, intracranial hemorrhage, or PDA, infant’s weight, gestational age, & chronological age & maintained within a therapeutic range. Caffeine has fewer side effects, once daily, more predictable plasma concentrations, slower elimination, & wider therapeutic range (rough, 5-20 mcg/ml) ○ Caffeine not widely used ○ Serum theophylline levels are measured first before administering, and consider gestational age and weight to determine dosage. It must be within normal levels before administration of the drug. Weight & urinary output should be closely monitored because both have mild diuretics. ○ Normal urine output per hour: 30 mL 2. Nasal CPAP & IMV ventilation – acts to maintain airway patency, effective for obstructive & mixed apnea. ● Nasal CPAP - Continuous Positive Airway Pressure helps prevent apneic episode, has an alarm if baby has an episode, nurse must count the number of seconds the baby is experiencing apnea. ● IMV - Intermittent Mandatory Ventilation. NURSING CARE 1. Monitoring respiration & heart rate. (bradycardia) 2. Cardiorespiratory monitors alert staff-preset delay time-15-20 seconds. ● DO NOT turn off alarms 3. If begun early, gentle tactile stimulation (rubbing back & chest gently, turning infant to supine position) ● baby may become cyanotic 4. If tactile stimulation fails to reinstitute respiration, flow-by oxygen & suctioning of nose & throat, if breathing does not begin, the chin is raised gently to open the airway, & resuscitate by mask & bag to lift the rib cage. Never shake. ● gentle suctioning - may affect vagus nerve that is connected to the heart ● Immediately connect to ventilator - CPAP ● resuscitate (light pressure only sa ambu bag - hyperextend the neck) 5. If breathing is restored, assess the infant for temperature, abdominal distention. ● abdomen may expand due to the interventions 6. Use pulse oximetry. to check oxygen saturation 7. Record apneic episodes. 9 8. If persistent & recurrent apnea, put the baby on mechanical ventilation / CPAP. REMEMBER: ● DO NOT turn off the alarm of the ventilators and monitors. What to do if the baby is in apneic episodes? ● Gentle stimulation, rub the chest and rub the back, supine position and turn to side ● Take note of its heart rate, color changes to pale or cyanotic What if the rubbing does not work? ● There is an oxygen and suction on the bed side. Connect the oxygen to the baby. Nasal Prong or mask, gentle suction the nose and throat. Vagus Nerve ● IF NOT PA DIN, They will do CPR, gentle only. Connect the baby to ventilator. ● ● Preterm is unable to initiate effective respirations as quickly as the mature infant, he is prone to irreversible acidosis. To prevent, the infant must be resuscitated within 2 minutes after birth. Birthing room should be prepared with: preterm-size laryngoscope (smallest, check battery), ET, suction catheters, & synthetic surfactant to be administered by endotracheal tube. Rolled diaper at the back and hyperextend the neck then insert laryngoscope. Ready micropore. Laryngoscope can be inserted through the nose or mouth. Usually orotracheal because they are nose-breathers. similar to anchoring NGT: II. IMPAIRED GAS EXCHANGE Nursing diagnosis ● Impaired gas exchange pulmonary functioning. related to immature Outcome Identification ● Newborn will initiate & maintain respirations after surfactant therapy. Outcome Evaluation ● Newborn initiates breathing at birth after resuscitation; maintains normal newborn respirations of 30 to 60 breaths / minute free of assisted ventilation; exhibits oxygen saturation levels of at least 90% as evidenced by arterial blood gases. ● Normal: 96-100%, 90% is acceptable for infants EXPLANATION Preterm infants have great difficulty initiating respiration at birth because the pulmonary capillary bed is immature. Lung surfactant does not form in adequate amounts until about the 34 to 35 week of pregnancy. maturity is at 37 weeks th ● ● The infant must be kept warm during resuscitation procedure, so he is not expending extra energy to increase the metabolic rate to maintain body temperature. Handle infants gently. Giving 100% oxygen during resuscitation or to maintain respirations presents the danger of pulmonary edema & retinopathy of prematurity (blindness of prematurity) when saturation of the blood with oxygen (PO2 of more than 100 mm hg which usually occurs when oxygen is administered at a concentration over 70%). With true apnea, the pause of respirations is more than 20 seconds & bradycardia does occur. III. RISK FOR DEFICIENT VOLUME th Thus, it may be inadequate, leading to alveolar collapse with each expiration. Breech born infants are apt to expel meconium into the amniotic fluid. If the fetus aspirates either vaginal secretions or meconium, the respiratory problem is further compromised. MEDICAL INTERVENTION: 1. Giving mother oxygen by mask during birth will help provide the preterm infant with optimal oxygen saturation at birth (85-90%). When determined premature, it is needed to give 02 via mask 2. Keeping maternal analgesia & anesthesia to a minimum offers the infant the best chance of initiating effective respiration. anesthesia can compromise the lung respiration by causing respiratory depression 3. Cesarean birth, although it has the advantage of reducing pressure on the immature head may lead to additional respiratory complications because of retained lung fluid Better option if premature but has complications Nursing diagnosis: ● Risk for deficient fluid volume related to insensible water loss at birth & small stomach capacity. ● mild diuresis can compromise the many fluids NB has so urine output needs to be monitored Outcome Identification ● Newborn will demonstrate intake of adequate fluid & electrolytes to meet body needs. Outcome Evaluation: ● Plasma glucose is between 40 & 60 mg per 100ml; specific gravity of urine is maintained at 1.003 to 1.030; urine output is maintained at a minimum of 1ml/kg/h; electrolyte levels are within normal levels. EXPLANATION The preterm newborn has a high insensible water loss due to large body surface compared with total body weight. The infant also is unable to concentrate urine well because of immature kidney function & thus excretes a high proportion of fluid from the body. higher surface body with fluids All these factors make it important that the preterm baby receive up to 160-200ml of fluid / kg of body weight daily (higher than the term infant). 10 IV fluid administration begins within hours after birth to fulfill this fluid requirement & provide glucose to prevent hypoglycemia. Given via continuous infusion pump (digital) to ensure a constant infusion rate & prevent accidental overload. o They are prone to infiltration, IV sites checked conscientiously because if infiltration should occur, the lack of subcutaneous tissue places the preterm newborn at risk for damaged tissue. They lack adequately sized peripheral veins; therefore IV/ umbilical venous catheter is used. ● prone to infiltration ● Umbilical cord is cut more than 5cm because it is difficult to insert a catheter. ● Cut longer to allow the doctors for umbilical catheterization. NURSING OUTCOMES CLASSIFICATION AND NURSING INTERVENTION CLASSIFICATIONS ● Monitor baby’s weight, urine output & specific gravity, & serum electrolytes to ensure adequate fluid intake. ● Over hydration may lead to non-nutritional weight gain, pulmonary edema & heart failure. ● Range of urine output for the first few days of life in preterm babies is high with that of the term baby: 40 to 100ml / 24 hours, compared with 10 to 20 ml/ kg/ 24 hours. ● Specific gravity is low-1.012, normal babies up to 1.030. ● Test urine for ketones & glucose. Hyperglycemia caused by glucose infusion may lead to glucose spillage into the urine & an accompanying diuresis. If too little glucose is supplied & body cells are using protein for metabolism, ketone bodies will appear in the urine. ● Blood glucose determinations every 4-6 hours help determine hypoglycemia or hyperglycemia. ● Blood glucose should range between 40 & 60mg/dl. ● Check for blood in the stools to evaluate for possible bleeding from intestinal tract. nutrients are not supplied, the infant will develop hypocalcemia (decreased serum calcium) or azotemia (low protein level in blood). Delayed feeding & a resultant decrease in intestinal motility may add to hyperbilirubinemia when fetal RBC begin to be destroyed. Nutrition problems are compounded by the preterm infant’s immature reflexes, which make swallowing & sucking difficult. The stomach’s capacity is small, possibly impeding nutrition. A distended stomach puts pressure on the diaphragm, which could lead to respiratory distress. Increased activity necessitated by ineffective sucking may increase the metabolic rate & oxygen requirements. Immature cardiac sphincter (between the stomach & the esophagus allows regurgitation to occur readily. The lack of cough reflex may lead the infant to aspirate regurgitated formula. Avoid regurgitation to avoid aspiration A. FEEDING SCHEDULE W/ the early administration of IVF to prevent hypoglycemia & supply fluid, feedings may be delayed until the infant has stabilized his respiratory effort from birth. ● Fed by Total Parenteral Nutrition until they are stable. ● Breastfeeding, gavage, or bottle feedings are begun as soon as the infant is able to tolerate them to prevent deterioration of the intestinal villi. ● Needs 115-140 calories / kg of body weight / day, compared with 100-110 needed by term infant. ● Protein requirement are 3 to 3.5 g/kg of body weight, compared with 2.0 to 2.5 for term newborn. ● Because preterm infant has a smaller stomach capacity, she should be fed more frequently with smaller amounts as 1 or 2 ml. every 2 to 3 hours. B. GAVAGE FEEDING IV. RISK FOR IMBALANCED NUTRITION: LESS THAN BODY REQUIREMENTS Nursing Diagnosis ● Risk for imbalanced nutrition, less than body requirements related to additional nutrients needed for maintenance of rapid growth, possible sucking difficulty, & small stomach. Outcome Identification ● Infant will receive adequate fluid & nutrients for growth during hospitalization. Outcome Evaluation ● Infant’s weight follows percentile growth curve; skin turgor is good; specific gravity of urine is maintained between 1.003 & 1.030; infant has no more than 15% weight loss in first 3 days of life & continuous to gain weight after. EXPLANATION: Nutritional problems arise because the body is attempting to continue to maintain the rapid rate of intrauterine growth. Therefore, the preterm newborn requires a larger amount of nutrients in the diet than the mature infant does. If these WHY GAVAGE FEEDING IS IMPLEMENTED? The gag reflex is not intact until an infant is 32 weeks gestation. The ability to coordinate sucking & swallowing is inconsistent until approximately 34 weeks’ gestation. ● Thus, infants born 32 to 34 weeks gestation & those who are ill or experiencing respiratory distress are usually started on gavage feedings because preemies have ineffective sucking which is not coordinated with swallowing & therefore, may aspirate. MEASUREMENT AND INSERTION 11 Measurement: When inserting NGT measure from the earlobe to the tip of the nose to the distal end of the sternum. xiphoid process They may be fed by continuous drip feedings at about 1 ml/h. Helpful for infants on ventilators or those who experience oxygen deprivation with handling. Insertion: Hyperextend the neck of the baby, pulupot ang tali and then going down not straight, because it can cause trauma. STOMACH CONTENT Position: large babies - sitting, pre-term - supine Materials: 20 or 60 cc syringe, micropore, stethoscope (for assessment of gurgling sounds), gloves As long as the infant is being gavage-fed, stomach secretions are usually aspirated, measured, & replaced before the feeding. An infant who has a stomach content of more than 2ml just before a feeding is receiving more formula than he can digest in the time allowed. Feedings should not be increased but possibly even cut back to ensure better digestion & decrease the possibility of regurgitation & aspiration. An infant who has a stomach content of more than 2ml, refer to doctor and suspend feeding ● CHECK CORRECT PLACEMENT OF THE TUBE BY: a. Aspirate gastric contents, Acidic - NGT in place tube must be in stomach Check if you are in the right place. Get the syringe and attach it to the end of the tube and aspirate the gastric content/gastric secretions/residual. b. Inject 5 cc of air then auscultate. If no gurgling sound is heard as air is injected, it means NGT is not in the stomach. When you aspirate 5cc of air, it means you are in the right way. Get stethoscope and put in xyphoid process. aspirate 5 cc of air then insert the it into the end of the tube to the stomach and push and hear a GURGLE SOUND. c. Measure the amount of residual, Subtract the same amount from the next feeding because this means that the baby is not able to digest all the milk that has been given to him. eg: doctor’s order is 2cc but there is 1cc residual, introduce additional 1cc only d. Put back the residual since it contains acids & the baby can develop metabolic alkalosis/ e. Keep NGT always closed to avoid abdominal distention. f. Fill syringe with formula before opening NGT, let it flow by gravity. g. Flush NGT w/ sterile water after giving formula in order to prevent clogging the NGT h. Minimal handling is necessary in order to conserve energy. Gavage - feeding Lavage - gastric washing, done when the baby is bleeding in NGT, use saline solution Assessments: Measure abdominal girth after feeding, high measurement means the feeding was not tolerated. If Tachypneic -> do not offer food, it may lead to aspiration FEEDING SCHEDULE May be given intermittently every few hours or continuously via tubes passed through the mouth or nose. ● ● ● ● ● C. FORMULA The caloric concentration of formulas used for preterm infants is usually 24 cal/oz, compared with 20 cal/oz for term infants. Supplementing minerals such as iron, calcium, & phosphorus chloride as necessary minerals are included in IV Vitamin K 0.5 is administered instead of 1 ml to term baby because of the infant’s small size. ready cotton ball before removing syringe Vitamin A is important in improving healing & possibly reducing the incidence of lung disease. Vitamin E important in preventing hemolytic anemia in preterm. Electrolytes such as sodium, potassium & chloride may be necessary. Breast milk is the best milk for preterm because of the immunologic properties play a major role in preventing neonatal necrotizing enterocolitis, a destructive intestinal disorder that often occurs in preterm babies. The mother can manually express breast milk for gavage feeding. V. INEFFECTIVE THERMOREGULATION NURSING DIAGNOSIS: Ineffective thermoregulation related to immaturity. Outcome Identification ● Infant will maintain body temperature within normal limits until term age. Outcome Evaluation ● Infant’s temperature is 97.6 degrees F (36.5degrees C) EXPLANATION Preterm has little subcutaneous fat for insulation & poor muscular development does not allow the child to move as actively as the older infant. Has a limited amount of brown fat, the special tissue present in the newborns to maintain body temperature. The infant is unable to shiver, a useful mechanism to increase body temperature; on the other hand, the child is unable to sweat & thereby reduce body temperature because of an immature central nervous system & hypothalamic control. Thus, the infant depends on the environmental temperature provided. In the delivery room, temperature is kept at 62 to 68 degrees F (16.6 to 20degrees C), the infant must be kept in a radiant 12 heat warmer. A 1500g infant exposed to this low, a temperature loses 1 degree C of body heat every 3 minutes if left unprotected. 8. 9. 10. 11. VI. RISK FOR INFECTION NURSING DIAGNOSIS: Risk for infection related to immature immune defenses in preterm infant Outcome Identification ● Infant will remain free of infection during hospital stay. Outcome Evaluation ● Temperature instability decreasing, being maintained at 97.6 degrees F (36. 5degrees C) axillary; absence of further s/s of infection such as poor growth or a reduced temperature 12. 13. 14. 15. 16. MAJOR COMPLICATING CONDITIONS: Severity of problems related to level of maturity: the earlier the infant is born, the greater the chance of complications. Major complicating conditions: a. Respiratory distress syndrome b. Thermoregulatory problems c. Conservation of energy d. Infection e. Hemorrhage VII. ASSESSMENT FINDINGS: 1. 2. 3. 4. 5. 6. 7. Respiratory system a. insufficient surfactant b. Apneic episodes c. Retractions, nasal flaring, grunting, seesaw pattern of breathing, cyanosis d. Increased respiratory rate Thermoregulation a. body temperature fluctuates easily (premature newborn has less subcutaneous fat & muscle mass) Nutritional status a. Poor sucking & swallowing reflexes b. Poor gag & cough reflexes Skin a. lack of subcutaneous fat; reddened; translucent Drainage from umbilicus/ eyes Cardiovascular a. Petechiae caused by fragile capillaries & prolonged prothrombin time b. Increased bleeding at injection sites Neuromuscular a. Poor muscle tone b. Weak reflexes c. Weak, feeble cry VIII. NURSING INTERVENTIONS: 1. 2. 3. 4. 5. 6. 7. Maintain respirations at less than 60/ minute, check every 1-2 hours Administer oxygen as ordered; check concentration every 2 hours to avoid retrolental fibroplasia (blindness) while providing adequate oxygenation. Auscultate breath sounds to assess lung expansion. Encourage breathing with gentle rubbing of back & feet. Suction as needed. Reposition every 1-2 hours for maximum lung expansion & prevention of exhaustion. Monitor for signs of infection; these infants have little antibody production & decreased resistance. 17. 18. 19. 20. 21. 22. 23. 24. Monitor blood gases & electrolytes. Maintain appropriate humidity level. Feed according to abilities. Monitor sucking reflex; if poor, gavage feeding indicated. Most preterm infants require at least some gavage feeding as it diminishes the effort required for sucking while improving the caloric intake. Use “premie” nipple if bottle- feeding. Monitor intake & output, weight gain or loss; these infants are easily dehydrated, with poor electrolyte balance. Monitor for hypoglycemia & hyper-bilirubinemia. Handle carefully, organize care to minimize disturbances. Do everything in one setting to prevent added stress. Provide skin care with special attention to cleanliness & careful positioning to prevent breakdown. Monitor heart rate & pattern at least every 1-2 hours; listen apically for 1 full minute. Monitor potential bleeding sites (umbilicus, injection sites, skin); these infants have lowered clotting factors. Monitor growth & development of the infant; check weight, length, head circumference. Provide tactile stimulation when caring for or feeding infants. Provide complete explanations for parents. Encourage parental involvement in infant’s care. Provide support for parents; refer to self-help group or other parents if necessary. Promote parental confidence with infant care before discharge. teach the caring to prevent aspiration especially if the baby stayed long in respirator The maturity of the newborn is determined by physical findings such as sole creases, skull firmness, ear cartilage, & neurologic findings that reveal gestational age, as well as the mother’s report of the date of her last menstrual period & sonographic estimations of gestational age. Amniocentesis or ultrasound– is a test for fetal maturity to avoid inducing labor prematurely. invasive, mandatory in USA IX. POST MATURITY Post-Maturity or Post Term Infants - born after the completion of 42 weeks of pregnancy or gestation. Problems of the post-term infant are associated with the progressively less efficient actions or capacity of placenta to sustain intrauterine life. The fetus who remains in utero w/ a failing placenta may die or develop post term syndrome. dehydrated ASSESSMENT FINDINGS 1. Skin ● Vernix & lanugo completely disappeared or absent ● Dry, cracked, parchment like appearance of skin or leather- like skin from lack of fluid & absence of vernix ● Color: yellow to green skin, nails & cord from meconium staining 2. Depleted or little subcutaneous fat with newborn old looking 3. Hard nails or long nails extending beyond fingertips. yellow nails due to passed meconium 13 4. 5. 6. Old man wrinkled appearance or “old man face” - due to intrauterine weight loss, dehydration, & chronic hypoxia. Signs of birth injury or poor tolerance of birth process Wide- eye alertness of a 1 -month -old baby, firm skull DIAGNOSTIC PROCEDURE 1. Ultrasound to measure the biparietal diameter of the fetus. 2. Non-stress test or complete biophysical profile to establish whether the placenta is still functioning. 3. Cesarean birth MANAGEMENT 1. Monitor vital signs 2. IV as ordered PROBLEMS 1. Difficulty establishing respirations especially if meconium stained or perinatal asphyxia. 2. Hypoxia due to asphyxia & cause increased in production of RBC 3. Meconium aspiration 4. Hypoglycemia owing to insufficient stores of glycogen which were used for nourishment in the last weeks of intrauterine life. 5. Subcutaneous fat levels may be low having been used up in the utero. 6. Tolerate stress of labor poorly 7. Temperature regulation difficult- cold stress, protect from chilling Management – Provide warm blanket, exposed to drop light or keep in isolette 8. Polycythemia from decreased oxygenation in the final weeks. Management - Partial exchange transfusion Heel prick - viscous 9. Elevated hematocrit because of polycythemia & dehydration which lowers the circulating plasma level. 10. Long term Problem 1. Poor weight gain 2. Low IQ scores NURSING INTERVENTIONS 1. Nursing care of the post mature infant has many characteristics in common with the care given to the premature infant 2. Design high-level nursing care to identify the infant’s specific physical & psychologic needs or parental teaching of newborn care. 3. Monitor functioning of all body systems, growth & development, parental support & teaching, & prevention of complications. 4. Parents hold infant, speak of the child in positive terms; state accurately why the infant needs to be closely observed in postnatal period. INTERVENTIONS (additional) ● Have the same developmental care that all other infants need. ● Singing or talking to the baby, stroking the child’s back & rocking the baby. ● Encourage parents to treat their baby as a fragile NB who needs warm nurturing, not as a tough big infant who has grown past that stage. ● Remind parents that the infant’s birth weight is not correlation of the child’s projected adult size. 14 Week 3: Acute Conditions of the Neonates I.

Hyperbilirubinemia G. Hemolytic Disease of the NB H. ABO Incompatibility A. RESPIRATORY DISTRESS SYNDROME (RDS) OR HYALINE MEMBRANE DISEASE Cause: inadequate lung surfactant Occurs in preterm infant, infants of diabetic mother, infants born by CS or those with decreased blood perfusion of the lungs. The pathologic feature of RDS is a hyaline-like (fibrous) membrane comprising products formed from exudate of the infant’s blood that lines the terminal bronchioles, alveolar ducts, & alveoli. This membrane prevents exchange of oxygen & carbon dioxide at the alveolar –capillary membrane. The cause is a low level or absence of surfactant, the phospholipid that normally lines the alveoli & reduces surface tension on expiration to keep the alveoli from collapsing on expiration. Pathophysiology High Pressure is required to fill the lungs with air for the first time & overcome the pressure of lung fluid. It takes a pressure between 40 & 70 cm H2O to inspire a first breath but only 15 to 20 cm H2O to maintain quite, continued breathing. If alveoli collapse with each expiration, as happens when surfactant is deficient & continues to take forceful inspiration to inflate them. A very immature infants release a bolus of surfactant at birth into their lungs from the stress of birth. However, w/ deficient surfactant areas of hypo-inflation occur & pulmonary resistance increased. Blood then shunts through the foramen ovale & the ductus arteriosus as it did during fetal life. The lungs are poorly perfused, affecting gas exchange. As a result, the production of surfactant decreases even further. The poor O2 exchange leads to tissue hypoxia which causes the release of lactic acid. This combined with the increasing carbon dioxide level resulting from the formation of the hyaline membrane on the alveolar surface, leads to severe acidosis. Acidosis causes vasoconstriction, & decreased pulmonary perfusion from vasoconstriction further limits surfactant production. With decreased surfactant production, the ability to stop alveoli from collapsing with each expiration becomes impaired. This vicious cycle continues until the oxygen carbon dioxide exchange in the alveoli is no longer adequate to sustain life without ventilator support. Summarized ver. of Pathophysiology Decreased pulmonary surfactant – increased surface tensionalveolar walls will not separate- lack of expansion of affected alveoli – decreased alveolar ventilation – inadequate exchange of O2 & carbon dioxide – hypoxia increased capillary permeability which causes effusion from the pulmonary capillaries into the alveoli & terminal – bronchioles- hyaline –like membrane found in the alveoli & bronchioles composed of mainly of fibrin – atelectasis. Additional Factors: a. Hypoxia, b. Patent ductus arteriosus c. Hyperbilirubinemia d. Retrolental fibroplasia e. Bronchopulmonary dysplasia (BPD)-damaged to the alveolar epithelium of the lungs related to high O2 concentration & + pressure ventilation f. Necrotizing enterocolitis Diagrammatic Presentation of RDS Assessment/ Signs & Symptoms 1. Low body temperature 2. Nasal flaring 3. Sternal & subcostal retractions 4. Tachypnea or Increased RR- more than 60/ m 5. Expiratory grunting- major symptom 6. Cyanotic mucous membranes 7. Rales 8. Respiratory acidosis a. Low Ph level (normal- 7.35- 7.45) b. Low PO2 level (normal -40-60 mm Hg) c. High PCO2 level (normal- 35-45) As distress increases: 1. Seesaw respirations-diaphragm descends causing the abdomen. to lift & the chest to sink 2. Heart failure evidenced by decreased urine output & edema of the extremities 3. Pale gray skin 4. Periods of apnea 5. Bradycardia 6. Pneumothorax Diagnostic Evaluation 1. Blood glucose- test hypoglycemia 2. Serum Calcium- test hypocalcemia 3. Blood gas- respiratory acidosis, PaO2- for hypoxia 4. Chest X-Ray (haziness) Beta –hemolytic B Streptococcus mimic RDS. Therapeutic Management 1. Administer Surfactant- through ET tube 2. Oxygen therapy, high humidity, warmth, -to provide adequate oxygen to tissues, to prevent lactic accumulation resulting from hypoxia & prevent the negative effects of oxygen therapy. CPAP - Continuous Positive Airway Pressure – Continues application of 3 to 8 cm H2O (positive) pressure to the airway, uses the infant’s spontaneous respiration to improve O2 by helping prevent alveolar collapse. Greatly improves oxygen exchange. IMV is used with Positive End-Expiratory Pressure (PEEP) allows to breath at their own rate but provides + pressure w/ 15 end-expiratory pressure to prevent alveolar collapse & overcome airway resistance. The PIP (Positive Inspiratory Pressure) is the maximum amount of + pressure applied to infant on inspiration. The total amount of pressure transmitted to the airway throughout an entire respiratory cycle is called mean airway pressure (MAP), improve oxygenation by maintaining functional residual capacity & overcoming the resistive forces of the atelectatic lung. SIMV - Synchronized Intermittent Mandatory Ventilationbreaths delivered by the ventilator are synchronized to the onset of spontaneous infant’s breaths. Complication of Positive Pressure Ventilation: Pneumothorax, pulmonary interstitial emphysema, pneumomediastinum 3. 4. 5. 6. 7. 8. 9. Monitor vital signs, arterial blood gases, skin color muscle tone Proper positioning; NPO; IV, NGT care Suction PRN Prevent complications Sodium bicarbonate – for acidosis (60 mL in glass) Changing infant’s position frequently Indomethacin – to cause closure of the patent ductus arteriosus Additional Therapy 1. Pancuronium (Pavulon) IV - muscle relaxant. 2. Extracorporeal Membrane oxygenation (ECMO) Management for chronic hypoxemia. 3. Nitric Oxide - causes pulmonary vasodilatation to help increase blood flow to the alveoli when persistent pulmonary hypertension is present. 4. Liquid Ventilation - Perfluorocarbons- effective in delivering O2 & surfactant. 5. Supportive Care- kept warm reduces metabolic oxygen demand. Prevention 1. Check the level of Lecithin/ Sphingo-myelin ratio in amniotic fluid by 2:1 2. Use tocolytic agents- terbutaline-prevents preterm birth by 2 injections of Glucocorticosteroid ● Ex. Betamethasone at 12 & 24 hours before birth at 24to 34 weeks pregnancy. Given to mother before birth if premature ● Signs of respiratory distress usually begins within 2 hours after birth: ● Grunting on expiration, ● Flaring of nostrils ● Tachypnea ● Chest retractions ● Generalized cyanosis ● Pallor ● Decreased breath sounds on auscultation of the lungs as lesser areas are functional ● Cough due to excessive lung secretions ● Chin lug ● Hypotension & shock The important surfactant that must be present at birth: a. Lecithin/ Sphingomyelin – 2:1 b. Phosphatidylcholine c. Phosphatidylglycerol Nursing Interventions: 1. Maintain an infant's body temperature at 97.6degrees F (36.5 degreesC). 2. Provide sufficient caloric intake for size, age, & prevention of catabolism (usually IV glucose with gradual increase in feedings). Nasogastric tube may be used. 3. Organize care for minimal handling of infant. 4. Administer oxygen therapy as ordered. a. Monitor oxygen concentration every 2-4 hours; maintain less than 40% concentration if possible. b. Oxygen may be administered by hood, nasal prongs, intubation, or mask. c. Oxygen may be atmospheric or increased pressure. d. Continuous positive air pressure (CPAP) or positive end-expiratory pressure e. (PEEP) may be used to prevent collapse & to keep alveoli expanded. 5. 6. 7. 8. 9. 10. 11. 12. 13. Therapeutic range is 10-12 cm of water pressure. ● First 72 hours – increase pressure to keep airway open ● After 72 hours – decrease pressure for airways are already open Oxygen should be warmed & humidified Monitor infant’s blood gases Eg: If intubated, suction (for less than 5 seconds) prn using sterile catheter. ● Bag the baby first: ambu-bag and ET-tube to prevent anoxia. Deliver oxygen first so that when ventilator is disconnected, has oxygen. ● Prolonging more than 5 seconds lead to anoxia ● Use sterile water in sterile cup if there are secretions Glucocorticoid (Celestone) – Artificial surfactant given at birth before the first breath or after diagnosis of RDS which is effective for up to 72 hours. ● Put in endotracheal tube ● Prevents lung collapse/atelectasis ● Surfactant can be administered by aerosol spray or ET tube. This surfactant will help to hasten lung maturity. BT to replace extracted blood used for tests. ● Another option - puncturing of heel ● Umbilical cut may be a source of infection. Give milk by gavage if NB has mild tachypnea Auscultate breath sounds. specially when baby is intubated ● check bilateral lung entry - same breath sounds on both right and left Provide chest physiotherapy, postural drainage, & percussion if ordered. ● cupping: using artificial nipple ● Nebulization: not attached on ET tube when to nebulize: should be before or after feeding WITH GAP. Encourage parental involvement in care (visiting, stroking infant, talking). ● if there is no contraindications Administer surfactant via endotracheal tube & other medications as ordered. 16 14. Place the newborn on the back or in a side lying position with the neck slightly extended. 15. Hold breastfeeding to conserve energy. Newborn may be on NPO & given IVF ● to avoid fatigue ● depending on residual - deduct feeding ● NPO - tachypnea, bradycardia, abdominal distension Normal Arterial Blood gases Temperature : 36.5- 37.5 pH : 7.35 -7.45 pCO2 : 35 – 45 pO2 : 80- 100 HCO3 : 22- 26 O2 saturation : 94-100% Base excess :+-2 C. MECONIUM ASPIRATION SYNDROME Meconium is present in the fetal bowel as early as 10 weeks gestation. An infant with hypoxia in utero experiences a vagal reflex relaxation of the rectal sphincter, which releases meconium into the amniotic fluid from pressure on the buttocks. Appears green to greenish black. Normal: breech presentation, abnormal: cephalic Cause: vagal reflex relaxation capillary: not on ABG Neonatal Newborn Distress Syndrome https://www.youtube.com/watch?v=xWe7Xwh7O1Y (video): Respiratory Distress in the Newborn https://www.youtube.com/watch?v=j3ypUlLMRLs (video): B. TRANSIENT TACHYPNEA OF THE NEWBORN ● ● ● NURSING CARE 1. Close observation of the NB is the priority. 2. Watch carefully that increased effort is not tiring. 3. Watch for beginning signs of a more serious disorder because rapid RR is the first sign of respiratory obstruction. One full minute RR. 4. Oxygen administration 5. Transient Tachypnea of the NB peaks at approximately 36 hours of life & slowly begins to fade at 72 hours as lung fluid is absorbed & respiratory activity becomes effective. At birth, a newborn may have a rapid rate of respiration, up to 80 breaths / minute when crying. Within 1 hour, this rapid rate slows between 30-60 breaths / minute. The respiratory rate remains at a high level, between 80-120 breaths/ minute. Signs & Symptoms 1. The infant does not appear to be in a great deal of distress, aside from the tiring effort of breathing so rapidly. 2. Has mild retractions but not marked cyanosis. 3. Mild hypoxia & hypercapnia 4. Feeding is difficult because the child cannot suck & breathe deeply at the same time. 5. Chest X-ray reveals some fluid in the central lung, but aeration is adequate. Chest did not expand that much Causes ● Result from slow absorption of lung fluid. ● Reflect a slight decrease in production of phosphatidyl glycerol or mature surfactant. These factors limit the amount of alveolar surface area available to the infant for gas exchange. Thus, the infant must increase the respiratory rate & depth to better use the surface available. Occurs more often in infants who are: 1. Born by cesarean section- because the thoracic cavity is not compressed by the force of vaginal birth, less lung fluid is expelled than normally. 2. Infants whose mothers received extensive fluid administration during labor 3. In preterm infants ● ● Asphyxia or other stress can cause passage of meconium before the fetus is born. Meconium aspiration syndrome occurs when the meconium-stained amniotic fluid is aspirated by the fetus before or after delivery. Aspiration of meconium in utero can cause chemical pneumonitis Asphyxia due to blockage of oxygen pathway two ways of meconium aspiration: 1. while in utero 2. after labor - Be cautious to prevent meconium swallowing. When diagnosed with meconium stain/amniotic fluid is swallowed, do not suction. Gasping reflex -> swallow. Suction after insertion of ET Tube, use a bulb syringe. Meconium can cause severe respiratory distress in 3 ways: 1. It can bring about inflammation of bronchioles because it is a foreign substance 2. It can block small bronchioles by mechanical plugging. 3. It can cause a decrease in surfactant production through lung cell trauma. Hypoxemia, carbon dioxide retention, & intrapulmonary & extrapulmonary shunting occur. A secondary infection of injured tissue may lead to pneumonia. Causes 1. Relaxation of anal sphincter 2. Accelerated intestinal peristalsis & passage of meconium 3. Reflex gasping & aspiration of meconium mixed in amniotic fluid (cause after delivery, even if baby is outside) Complications 1. Air leak 2. Pulmonary hemorrhage 3. Pulmonary interstitial emphysema 4. Pulmonary hypertension 5. Pneumonia 6. Infection 7. Thrombocytopenia- deficiency of platelet 8. Asphyxia 17 Assessment 1. Difficulty establishing respirations at birth- meconiumstained amniotic fluid. Not born breech- hypoxia 2. Apgar score low (poor) 3. Tachypnea, retractions & cyanosis 4. Poor gas exchange- decreased PO2 & increased PCO2 5. Continue to have retractions due to inflammation of bronchi tends to trap air in the alveoli causing enlargement of the antero-posterior diameter of the chest (barrel chest). Diagnostic Tests 1. Chest X-ray will show bilateral coarse infiltrates in the lungs, w/ spaces of hyperaeration, (honeycomb effect), diaphragm will be pushed downward. 2. Complete blood count to check if WBC count is high -> baby has infection 3. C-reactive protein -> infection 4. Blood cultures -> to check what organism is sensitive to the baby. Wait for result before antibiotic (36-72 hours). This prevents taking antibiotics that are resistant to the organism. Therapeutic Management 1. Intrapartally, amnio transfusion may be used to dilute the amount of meconium in amniotic fluid to reduce the risk of aspiration. To prevent aspirating thick meconium. 2. Suctioning after the head is delivered with a bulb syringe, or a catheter after the endotracheal tube is inserted while at the perineum. 3. After tracheal suction, oxygen administration & assisted ventilation. 4. Administer prescribed: ○ Antibiotic therapy - prevent pneumonia ○ Bicarbonate for acidosis 5. Monitoring of blood gases *as ordered 6. Watch out for seizures, GIT bleeding & renal failure 7. Observe closely for pneumothorax - due to trapping of air in the alveoli. through auscultation 8. Observe for signs of heart failure (increased RR & signs of respiratory distress) 9. Maintain a temperature-neutral environment to prevent increasing the metabolic oxygen demands. 10. Chest physiotherapy with clapping & vibrationremove remnants of meconium. look in X-ray what part of the lung needs it so you can concentrate on that part (eg: right, left, lower or upper lung). Done by RT, or Nurses during position change and after suctioning D. APNEA Apnea is a pause in respirations longer than 20 seconds with accompanying bradycardia Beginning Cyanosis may be present. Preterm infants have periods of apnea due to fatigue or the immaturity of their respiratory mechanism. Babies with secondary stresses such as infection, hyperbilirubinemia, hypoglycemia, or hypothermia have high incidence of apnea. Management 1. Gently shaking the baby or flicking the sole of the foot stimulates the baby to breathe. 2. If infant does not respond, resuscitation is necessary. 3. Apnea monitors that record respiratory movement. 4. Ventilator - for infants with frequent or difficult to correct episodes. 5. Maintain a neutral thermal environment & gentle handling to avoid excessive fatigue. 6. Suction gently to minimize nasopharyngeal irritation, which can cause bradycardia due to vagal stimulation. 7. Use indwelling NGT rather than intermittent reduce the amount of vagal stimulation. Difference: indwelling - as is (up to 3 days only for infection control), letting it stay there. Intermittent frequent changing, inserting and removing every feeding. 8. After feeding, observe the infant carefully because the full stomach can put pressure on the diaphragm. Burp to reduce the effect. 9. Never take rectal temperatures 10. Theophylline or caffeine sodium benzoate administered to stimulate respirations - increase an infant’s sensitivity to carbon dioxide, ensuring better respiratory function. E. SUDDEN INFANT DEATH SYNDROME Sudden Infant Death Syndrome (SIDS) is the sudden, unexplained death in infancy or unexpected death of an apparently healthy infant under 1 year of age in which a thorough autopsy fails to demonstrate an adequate cause of death. unknown cause but common below 1 year of age Factors and Causes: It tends to occur at a higher rate in the infants of: 1. Adolescent mothers 2. Infants of closely spaced pregnancies 3. Underweight infants 4. Preterm infants 5. Bronchopulmonary dysplasia 6. Twins 7. Siblings of another child with SIDs caution the mother, must be well monitored 8. Native American & Alaskan infants 9. Economically disadvantaged black infants 10. Infants of narcotic-dependent mothers Other possible contributing factors: 1. Viral respiratory or botulism infection 2. Pulmonary edema 3. Brain stem abnormalities 4. Neurotransmitter deficiencies 5. Heart rate abnormalities 6. Distorted familial breathing patterns 7. Decreased arousal 8. Possible lack of surfactant in alveoli 9. Sleeping prone - resp. muscles restricted) Age: Peak incidence is between 2-4 months of age Time of Year: esp. during winter months. Time of Death: During Sleep Cause - unknown 18 Sleep Risk Habits: A. prone sleeping position B. Overheating (thermal stress) C. Use of soft bedding D. Possibly sleeping with an adult E. Respiratory disorders, F. History of life- threatening event, Maternal risk factors: A. Maternal smoking B. Young mothers age C. High risk pregnancy D.

May be clutching bedding 5. Diaper is wet & full of stool Diagnostic ● No test can predict risk ● Cardiopneumogram or pneumocardiogram Nursing Intervention / Prevention 1. Apparent life- threatening event a. Home cardiorespiratory event monitor - discontinue monitor 2-3 months without episodes. b. Administer respiratory stimulant medications theophylline or caffeine as prescribed Emergency 1. Review scenario 2. Healthy infants should be placed in supine position for sleep. supine-lying position 3. Infants with gastroesophageal reflux or other airway anomalies that predispose to airway obstruction may be placed in a prone position. to prevent aspiration of gastric reflux. It will flow by gravitational pull 2. Soft moldable mattress & bedding, such as pillows should not be used. To prevent falling down on the face. It can suffocate the baby. 3. Stuffed animals should be removed from the crib while sleeping. To also prevent the baby from suffocation. 4. Allow the parents & family to say good-bye to their infant 5. Clean the infant before allowing the family to see him. 6. Make an appropriate referral for follow-up with the family. Public Health Nursing ● Encourage the expression of feelings ● Explore coping mechanisms & evaluate effectiveness ● Assess parental intellectual knowledge ● Provide written information about SIDS F. HYPERBILIRUBINEMIA Hyperbilirubinemia (an elevated level of bilirubin in the blood) results from destruction of red blood cells by either a normal physiologic process or the abnormal destruction of red blood cells. Refers to an excessive level of accumulated bilirubin in the blood & is characterized by jaundice, or icterus, a yellowish discoloration of the skin, sclera, & nails. Best assessment: natural light, light pressing of nose or chest bone: yellow. If it progresses, sclera is yellow. Hyperbilirubinemia may result from increased unconjugated or conjugated bilirubin. Most common is unconjugated bilirubin. Pathophysiology Bilirubin is one of the breakdown products of the hemoglobin that results from red blood cell (RBC) destruction. When RBCs are destroyed the breakdown products are released into the circulation, where the hemoglobin splits into two fractions heme & globin. ● The globin (protein) portion is used by the body, ● The heme portion is converted to unconjugated bilirubin; an insoluble substance bound to albumin. In the liver the bilirubin is detached from the albumin molecule &, in the presence of the enzyme glucuronyl transferase, is conjugated with glucuronic acid to produce a highly soluble substance, conjugated bilirubin glucuronide, which is then excreted into the bile. In the intestine, bacterial action reduces the conjugated bilirubin to urobilinogen, the pigment that gives stool its characteristic color. Most of the reduced bilirubin is excreted through the feces, a small amount is excreted in the urine. Normally the body is able to maintain a balance between the destruction of RBCs & the use of excretion of by-products. However, when developmental limitations or a pathologic process interferes with this balance, bilirubin accumulates in the tissues to produce jaundice. Possible Causes of Hyperbilirubinemia 1. Physiologic (developmental) factors (prematurity) 2. An association with breastfeeding or breast milk due to substances in the maternal milk such as” ● B-glucuronidase & non-esterified fatty acids which may inhibit normal bilirubin metabolism ● or pregnanediol (a breakdown product of progesterone) in breastmilk depresses the action of glucuronyl transferase, the enzyme that converts indirect bilirubin to the direct form, which is readily excreted in bile. indirect bilirubin must be converted to direct to excrete it. 3. Excess production of bilirubin (hemolytic disease, biochemical defects, bruises) cephalohematoma - normal jaundice but disappears from 2-6weeks. 4. Disturbed capacity of the liver to secrete conjugated bilirubin (enzyme deficiency, bile duct obstruction-> plugging of biliary secretions - when obstructed bile is unable to enter the intestinal tract, accumulates in the liver. Bile pigments (direct 19 5. 6. 7. bilirubin) enter the bloodstream & jaundice (physiologic) occurs.) Combined overproduction & under secretion (sepsis) Some disease states (hypothyroidism, galactosemiagenetic metabolic disorder that affects an individual’s ability to metabolize the sugar galactose properly, infant of diabetic mother) Diseases part of Newborn Screening Genetic predisposition to increased production (Native Americans, Asians) permanent cell damage & scarring of the basal ganglia & brain stem called kernicterus. Nursing intervention Nursing Intervention for physiologic jaundice in NB is rarely necessary except for: 1. 2. 2 Types of Jaundice depends on the day it appears. Physio - 2nd-3rd, Patho - first 24 hrs or 1st day 1. Physiologic jaundice or icterus – term infants, starts on the 2 day or 3rd day of life in about 50% of all newborns as a result of the breakdown of fetal RBC. ● Bilirubin levels gradually increase to approximately 6mg/dl on the 3 day of life or 72 hours, then decrease to a plateau of 2 to 3 mg/dl by the 5 day. ● Preterm infants – serum bilirubin levels may peak as high as 10 to 12 mg/dl at 4 to 5 days and decrease slowly over a period of 2 to 4 weeks. more common and normal to them due to immaturity of the liver. nd rd th 2. Pathologic jaundice - usually appears early, up to 24 hours after birth; represents a process ongoing before birth. Pattern of progression is from head to feet. ● Blanch the skin over the bony area or look at conjunctiva & buccal membranes in dark skinned infants. With disease process 3. 4. 5. 6. 7. 8. Early feeding to speed passage of feces through the intestine & prevent reabsorption of bilirubin from the bowel Phototherapy (exposure to infant to light) to initiate maturation of liver enzymes may be used, used to help convert unconjugated (insoluble) bilirubin to conjugated (soluble) & move from the skin to the blood plasma & then excreted. ● Baby must be naked ● Turn every 2 hours to expose all parts. Completely undress the infant except for the diaper with eye patches to protect the eyes from the high intensity fluorescent lights. Remove eye patches during assessment & feeding. Maintain temperature regulation due to large surface area being exposed to environmental temperatures ● high temperature may cause hyperthermia Maintain adequate hydration due to increased excretion of conjugated bilirubin through the bowel & urinary system. ● IV fluids: for them to be hydrated to aid the excretion of bilirubin levels ● If good sucking power: additional water and fluids ● may also cause excretion in sweat, urine (yellowish) Monitor serial fractionated bilirubin levels to evaluate the infant’s condition. Instruct the parents on the disease & the expected care of the infant. Diagnostic evaluation The degree of jaundice is determined by serum bilirubin measurements. ● order may occur every hour if the levels are too high Phototherapy is not always the intervention for jaundice (case to case basis) Normal values of unconjugated bilirubin are 0.2 to 1.4 mg/dl. In the newborn, levels must exceed 5mg/dl before jaundice is observable. Intervention for pathologic: depending on the degree: exchange transfusion, because rH/ABO incompatibility increases bilirubin levels Evaluation of jaundice is based on: 1. Serum bilirubin levels 2. Timing of the appearance of clinical jaundice 3. Gestational age at birth premature are prone 4. Family history including maternal Rh factors maternal rH incompatibilities 5. Age in days since birth patho or physio 6. Feeding method if physio, continue BF 7. Infant’s physiologic status 8. The progression of serial serum bilirubin levels Diagnostic Tests a. Physical examination to check for cephalocaudal progression of dermal icterus b. Serum bilirubin determination *upon doctor’s order Criteria of Pathologic Jaundice ● Appearance of jaundice within 24 hours ● Persistent jaundice after 1 (term neonate) or 2 preterm weeks At 10–12 mg/100 mL: If the level of indirect serum bilirubin rises above 10 to 12 mg./ 100ml. Treatment will be considered although age, maturity & breastfeeding affect this. At about 20mg/ 100ml: Enough indirect bilirubin has left the bloodstream that it could interfere with the chemical synthesis of brain cells, resulting in G. HEMOLYTIC DISEASE OF THE NEWBORN (Erythroblastosis fetalis) Hemolytic - characterized by destruction(lysis) of red blood cells Caused by: 1. ABO incompatibility 2. Rh factor 3. Maternal antibodies 4. Complications include (neurological damage) anemia, kernicterus Assessment: a. Jaundice due to hyperbilirubinemia b. Pallor due to hemolytic anemia 20 Diagnostic Test a. Cord blood studies puncture and get blood sample in the cord use the blood sample from the cord in the following test too: b. Complete blood count c. Reticulocyte count d. Bilirubin red blood cells early in pregnancy if the fetus is Rh positive. By the end of the second pregnancy, a fetus can be severely compromised by the action of these antibodies crossing the placenta and destroying RBC. 1. 2. Mechanism of Rh Incompatibility: a. b. c. d. e. f. Sensitization of Rh-negative women by transfusion of Rh-positive blood. Sensitization of Rh-negative woman by presence of Rh Positive RBCs from her fetus conceived with Rh-positive man 65% of infants conceived by this combination of parents will be Rh +. Mother is sensitized by passage of fetal Rh-positive RBC’s through placenta, either: ● INSIDE: during pregnancy (break /leak in membrane) ● OUTSIDE: or at the time of separation of the placenta after delivery. This stimulates the mother’s immune response system to produce anti-Rh-positive antibodies that attack fetal RBC’s & cause hemolysis. If this sensitization occurs ● during pregnancy: the fetus is affected in utero ● at the time of delivery: subsequent pregnancies may be affected. Next babies will have positive rH too. H. ABO AND RH INCOMPATIBILITY ABO incompatibility: a. Same underlying mechanism b. Mother is blood type O; infant is A, B, or AB c. Reaction in ABO incompatibility is less severe. rH is more severe with higher bilirubin levels Nursing Interventions: a. Provide phototherapy done while doing exchange transfusion b. Monitor laboratories c. Assist with exchange transfusion Through umbilical cord catheterization: 5cc out and in, with specific amount of blood depending on the severity of the bilirubin blood level. Rh incompatibility: No direct connection exists between the fetal & maternal circulation, & no fetal blood cells enter the maternal circulation. If the mother’s blood type is Rh (D) negative & the fetal blood type is Rh positive (contains the D antigen): ● The introduction of fetal blood causes sensitization to occur, & the mother begins to form antibodies against the D antigen. ● Most form in the mother’s blood stream in the first 72 hours after birth because there is an active exchange of fetal – maternal blood as placental villi loosen & the placenta is delivered. ● After this sensitization, in a second pregnancy, there will be a high level of antibody D circulating in the mother’s bloodstream, which acts to destroy the fetal ● ● 3. 4. 5. ● 6. 7. 8. First pregnancy: mother may become sensitized, baby rarely affected Indirect Coombs test (tests for anti-Rh-positive antibodies in mother’s circulation) performed during pregnancy at first visit & again about 28 weeks’ gestation. If indirect Coombs test is negative at 28 weeks, a small dose of (MicRhogam) is given prophylactically to prevent sensitization in the third trimester. Rhogam may also be given after the second trimester amniocentesis. If positive, levels are titrated to determine extent of maternal sensitization & potential effect on fetus. Direct Coombs test done on cord blood at delivery to determine presence of anti-Rh –positive antibodies on fetal RBCs. If both indirect & direct Coombs tests are: negative (no formation of anti-Rh-positive antibodies) & infant is Rh positive, then Rh-negative mother can be given RhoGam (RhoD) human immune globulin) to prevent development of anti-RH-positive antibodies as a result of sensitization from present (just terminated) pregnancy. In each pregnancy, an Rh-negative mother who carries an Rh-positive fetus can receive RhoGam to protect future pregnancies if the mother has had negative indirect Coombs tests & the infant has had positive direct Coombs tests. - mother, + fetus = rhogam If the mother has been sensitized (produced anti-Rhpositive antibodies), RhoGam is not indicated. RhoGAM must be injected into an unsensitized mother’s system within the first 24 hours if possible, by 72 hours at the latest. ABO Incompatibility: 1. The maternal blood type is O & the fetal blood type is A 2. Occur when the fetus has type B or AB blood 3. A reaction in an infant with type B blood is often serious. 4. Hemolysis can become a problem with a first pregnancy in which there is ABO incompatibility. ● Reaction less severe than with Rh incompatibility. ● First born may be affected because Type O mother may have anti-B antibodies even before pregnancy. ● Fetal RBCs with A, B, or AB antigens evoke less severe reactions on part of the mother, thus fewer anti- A, anti-B, or anti-AB –antibodies are produced. ● 4. Clinical manifestations of ABO Incompatibility are milder & shorter duration than those of Rh incompatibility. ● Care must be taken to observe for hemolysis & jaundice. Assessment ● Rh incompatibility of the NB can be predicted by rising anti-Rh titer or a rising level of antiBodies (indirect Coombs test) in the mother during pregnancy. Confirmed by detecting antibodies on the fetal erythrocytes in cord blood (positive direct Coombs test) by umbilical cord sampling. The mother 21 have Rh-negative blood (dd), & the baby will be Rh positive) or Dd). cord blood confirms HYDROPS FETALIS - pathologic accumulation of at least 2 or more cavities w/ a collection of fluid in the fetus. ● Indirect bilirubin is fat-soluble & can’t be excreted from the body. The liver enzyme glucuronyl transferase converts indirect bilirubin to direct bilirubin. baby will also be jaundice ● Direct bilirubin is water-soluble & combines with bile for excretion from the body with feces. In preterm, the liver is unable to convert bilirubin thus jaundice is extreme. feces, sweating, urine ● Normally cord blood has an indirect bilirubin level of 0 to 3 mg/100ml. ● An increasing indirect bilirubin level is dangerous if the level rises above 20mg/dl in term infant or 12mg/dl in a preterm infant - brain damage from kernicterus (invasion of bilirubin in brain cells) occur. Therapeutic Management: ● Early feeding ● Phototherapy- 12- 30 in’ above NB’s bassinet ● Exchange blood transfusion- Monitor HR, RR, & BP o 5mg/ 100 ml at birth o 10mg/ 100ml at age 8 hours o 12 mg/100ml at age 16 hours o 15 mg/100ml at 24 hours depends on time of birth Assessment: 1. Jaundice BOTH ABO and rH causes pathologic jaundice ABO has less severity of jaundice 2. Anemia 3. Erythropoiesis- production of RBC 4. Enlarged placenta 5. Edema & ascites Nursing Interventiont: 1. Determine blood type & Rh early in pregnancy. 2. Determine results of indirect Coombs test early in pregnancy & again at 28-32 weeks. ordered by the doctor 3. Determine results of direct Coombs test on cord blood (type & Rh, hemoglobin & hematocrit). 4. Administer RhoGam IM to mother as ordered. 5. Monitor carefully infants of Rh-negative & type O mothers for jaundice. 6. Set up phototherapy as ordered & monitor infants during therapy. 7. Support parents with explanations & information. 22 Week 4: Upper Respiratory Tract Disorders I. OUTLINE UPPER RESPIRATORY TRACT A. Choanal Atresia B. Acute Nasopharyngitis C. Pharyngitis C.1.

Epiglottis Care of Client with Upper Respiratory Disorder Learning Objectives After lecture /discussion, the students will be able to: 1. Review the anatomy & physiology of the upper & lower respiratory disorders. 2. Identify the different disorders of the upper & lower respiratory disorders 3. Define related terms. 4. Discuss the signs & symptoms of each problem. 5. Explain the Nursing Implications of each disorder right lobe = 3, left lobe = 2 UPPER RESPIRATORY TRACT ● ● ● ● ● A. CHOANAL ATRESIA Choanal Atresia; Pink on crying, blue on breastf… Refers to an obstruction, either unilateral or bilateral, of the posterior nares. Prevents newborns (who up to age 3 months are natural nose breathers) from drawing air through the nose & down into the nasopharynx. The condition may be congenital or may be caused by an obstructing membrane or bony growth. Thre’s a leakage of air Treatment for bilateral atresia involves: ● Piercing of the obstructing membrane. ● Surgical removal of the bony growth. as the child grows, needs more air to breathe, may have another surgery as he/she grows older Assessment Findings: ● Respiratory distress at birth or immediately after the infant quiets & tries to breathe through the nose. 23 ● ● Air hunger when the mouth is closed. Air hunger & cyanosis at feeding. pink when crying, bluish when cyanotic = obligatory nasal breathers, leak of air in the mouth when crying causes pink color Nursing Implications: ● Assess for choanal atresia, by gently compressing first one nostril & then the second; if present, struggling secondary to air hunger occurs. assessment 1): occlude one nostril and observe inhalation, repeat on the next side to check if unilateral or bilateral. assessment 2): cover the mouth of the baby then observe for any presence of cyanotic ● Pass a soft no. (Fr)ench 8, 10 catheters through the posterior nares to the stomach in the delivery room. If such catheter does not pass bilaterally, diagnosis of choanal atresia is confirmed. Confirm: insert a nasal suction catheter or NGT tube and check if it will go down. There will be blockage. ● Ensure adequate hydration & glucose levels by administering intravenous fluids for infants with difficulty feeding. ● Help the parents to understand the anatomic problem & how surgical intervention may be required. ● Insert an oral airway, if necessary. to avoid Respiratory Distress ● Provide the parents with emotional support & information. ● Allow the parents to see their child as soon as the procedure is over. ● Prepare the parents & the infant for discharge & answer any questions the parents may have. ● Because of difficulty with feeding, they may receive IVF to maintain their glucose & fluid level until surgery can be performed. B. ACUTE NASOPHARYNGITIS Acute Nasopharyngitis referred to as - (Common Cold) ● The most frequent infectious disease in children, is caused by one of several viruses. ● The most common causative organism are: rhinovirus, coxsackie virus, respiratory syncytial virus adeno virus, parainfluenza viruses. ● ● ● ● Children are commonly exposed to colds at school from other children; toddlers average 10-12 colds a year; school –age children & adolescents have 8 to 10 colds a year. The incubation period for a cold is 2-3 days. Children who are in ill health from some other cause are more susceptible to the cold viruses than are well children. Stress factors appear to play a role in developing a cold. ● ● Other possible factors associated with increasing the susceptibility to colds include exposure to drafts, cold feet, & chilling. if bed is adjacent to window during cold seasons Immune system compromised Assessment/Symptoms: A. begin with nasal congestion, B. a watery rhinitis prevent rough handkerchief, it can irritate C. a low- grade fever- 102F to 104F (38.8- 40C) D. Dehydration- refuse feedings why? because baby cannot eat E. Reddened, swollen nasal mucous membrane F. Difficulty in breathing secondary to nasal edema & congestion G. Pharyngitis secondary to posterior rhinitis & local irritation H. Cough secondary to draining pharyngeal secretions post-nasal drip I. Swollen & palpable cervical lymph nodes last about a week & then symptoms fade. Is it bad to have palpable lymph nodes? No, it acts as a defense mechanism or “soldier” and part of the immune system. J. Thick, purulent nasal discharge secondary to bacteria such as streptococci causing secondary infection virus - clear bacteria - green / yellow K. May develop secondary symptoms, such as vomiting, & diarrhea. Nursing Implications: 1. There is no specific treatment because it is caused by a virus, unless secondary bacterial infection has occurred- antibiotics. 2. Monitor vital signs 3. Control fever - oral temperature 38.4C or 101F antipyretics - Acetaminophen (Tylenol) be given. no antibiotic if viral cough - expectorant 4. Monitor fluids & electrolytes in infants & toddlers. hydration is needed action of fluid in the baby - liquifies the phlegm for easy expectoration 5. Keep in mind that symptoms persist for approximately 1 week & then subside. 6. Teach the parents how to monitor young children for dehydration. 7. Teach the parents that acetaminophen is for fever reduction & does not reduce cold symptoms. 8. Teach the parents to instill saline nose drops or spray for nasal congestion- to liquefy nasal secretions & help them drain. 9. Teach the parents correct use of bulb suction to clear nasal mucous by compressing the bulb before insertion into the child's nostril - allows them to breathe more efficiently. some mothers do this manual sucking 10. Guaifenesin - loosens secretions but does not suppress cough. some buys OTC, pharmacist should ask if cough is productive (with phlegm) or non-productive (no phlegm) suppressant = for sleep 11. Encourage the parents to use cool mist vaporizer to help loosen nasal secretions. 24 nebulizer 12. Administer phenylephrine nose drops to tree the airway by constricting the mucous membrane. To minimize congestion 13. Encourage fluids & maintain hydration. 14. Encourage good hand washing to prevent the spread of colds. 15. Explain to parents that antihistamine, antibiotics, & expectorants are not generally recommended. drink liberal amounts of water sucking difficulty for baby - IV 16. Teach the parent that it is not necessary to suppress the cough because this mobilizes secretions & prevents pooling & subsequent infection unless ordered. 17. Teach the parents about the safe use of vaporizers such as cleaning, & safe placement to prevent burn injury to the child from the steam. steam home remedy -> rolled cardboard then the baby inhales on the other side so the vapor will be inhaled. loosens congestion -> minimizes congested nares -> more comfortable breathing → 1 foot distance Home remedy: “Suob” ● ● cold first Peak incidence occurs between 5 & 15 years old, incubation period-2-5 days. Occur as a result of chronic allergy in which there is constant postnasal discharge that results in secondary irritation. post nasal discharge can be swallowed when lying down C.1. VIRAL PHARYNGITIS Causative agent is virus, symptoms are: Generally mild: ● Sore throat ● Fever ● General malaise ● Enlarged lymph nodes ● Erythema present at the back of the pharynx & the palatine arch 18. Teach the parents the signs of otitis media (middle ear infection), elevated temperature, & ear pain because this can be a complication of the common cold & requires treatment. holding the portion of the ear may indicate the child/baby is in pain secretion (luga) that is foul smelling treated using ear drop, cleanse secretion. Nursing Diagnosis: ● Parental health seeking behavior related to management of child’s cold. Outcome Identification ● Parents will demonstrate knowledge of what is & what is not helpful in the treatment of a cold by end of health visit. Outcome Evaluation ● Parents state intention to use cool mist vaporizer to loosen secretions, to encourage oral fluid, to administer an antipyretic to reduce fever, & to avoid cough medicine. ● Care of a child with cold is primarily supportive- loss of appetite – give liquid to solid foods. ● ● C. PHARYNGITIS It is an infection & inflammation of the throat, bacterial or viral in origin. Frequently accompanies the common cold. Treatment for viral pharyngitis is directed to comfort interventions, such as acetaminophen for pain & fever or gargling with warm water. acetaminophen is analgesic and antipyretic ● Group A beta-hemolytic streptococcus is the organism most frequently involved in bacterial pharyngitis, usually affecting children age 6 & older. ● Treatment for streptococcal pharyngitis is a full-day course of antibiotics, such as Clindamycin or amoxicillin. ● Children not fully treated can develop a hypersensitivity reaction resulting in rheumatic fever (rare). some have financial incapacity and stops treatment, it may cause reaction rheumatic fever affects the heart - Penicillin G (Pen G). Hard to inject, very viscous. ● Symptoms of acute glomerulonephritis may appear in 1 to 2 weeks after streptococcal pharyngitis regardless of a full course of antibiotics. ● If the bacterial strain was a nephrogenic one, the chances are as high as 50% that the kidney disease will develop. Laboratory studies: –increase WBC count. ● ● If inflammation is mild, children rarely need more than an oral analgesic such as acetaminophen or ibuprofen for comfort. Warm heat applied to external neck area using a warm towel or heating pad can be soothing. not to hot it may scald the head 25 ● ● Sore throat - give liquid to solid food. Observed closely infants until inflammation & tenderness diminish to be certain they take in sufficient fluid to prevent dehydration. C.2 STREPTOCOCCAL PHARYNGITIS Between ages- 5-15 years. Organism: Group A beta-hemolytic streptococcus- bacterial pharyngitis in children. Must be taken seriously because they can lead to cardiac & kidney damage from an auto immune process. Assessment Findings: ● Erythematous & enlarged palatine & tonsils (bright red) ● White exudate in the tonsillar crypts/pus ● Petechiae present on the palate. ● High fever ● An extremely sore throat ● Difficulty swallowing, ● Lethargy ● Temperature usually elevated to as high as 104F(40C) ● Headache ● Swollen abdominal lymph nodes may cause abdominal pain ● Throat cultures confirm the presence of Streptococcus bacteria - virulent causing necrosis of tissue & extensive damage. Nursing implications: ● Encourage parents always to have the child with pharyngitis seen at a health care facility. ● Tell parents that the child needs to have a throat culture because it is impossible to discriminate between pharyngitis, from a virus or streptococcal pharyngitis, which requires treatment to prevent life-threatening illness. ● Educate parents on the importance of administering a full 10-day course of an oral antibiotic - Penicillin G or single injection of benzathine penicillin G to ensure that streptococci are completely eradicated. ● Cephalosporins or broad-spectrum macrolides – Erythromycin- if resistant organisms are known in the community ● Hypersensitivity or autoimmune reaction to group A streptococci that results in rheumatic fever & glomerulonephritis. ● Symptoms of acute glomerulonephritis: o Blood & protein in urine appear in 1 to 2 weeks after pharyngitis. not normal in urine o 2 weeks after treatment - check urine specimen for protein to check for developing glomerulonephritis. urinalysis ● Instruct parents about measures for rest, ● Relief of throat pain ● Maintain hydration ● Examined by a health care personnel ● Instruct the parents on appropriate comfort measures for the child. ● Inform the parents that the child with streptococcal pharyngitis is infectious until the 24 hours after antibiotics have begun. after 24 hours of antibiotic, free from infecting others ● Ensure that the child returns to the health care facility 2 weeks after treatment to obtain a urine specimen (urinalysis) & evaluate for poststreptococcal glomerulonephritis D. TONSILLITIS Refer to infection & inflammation of the adenoid(pharyngeal) tonsils. Adenitis – infection & inflammation of the adenoid (pharyngeal) tonsils. Tonsillar tissue is lymphoid tissue that filters pathogenic organisms from the head & neck area. palatine tonsil meets at midline, with exudates, almost touching the uvula Tonsil grading 1. The palatine tonsils are located on both sides of the pharynx 2. The adenoids are in the nasopharynx 3. Tubal tonsils are located at the entrance to the eustachian tubes 4. Lingual tonsils are located at the base of the tongue. All of these tonsils are referred as Waldeyer’s ring, are easily infected because of the bacteria that pass through or through them with lymph. Treatment of Choice: Currently, tonsillectomy, removal of the palatine tonsils, is not recommended unless all other measures prove ineffective. 26 to avoid rheumatic fever: tonsil engulfs the microorganisms before it enters the tract. If there are frequent attacks (6 times a year) it is removed. ● ● Adenoidectomy- removal of the pharyngeal tonsils. ● ● ● ● ● ● ● ● ● Assessment Findings: ● Drooling because their throat is too sore for them to swallow saliva. Swallowing is so painful that it feels as if they are swallowing bits of metal or glass. ● High fever ● Lethargic ● Sore throat ● Tonsillar tissue appears bright red & enlarged that 2 areas of palatine tonsillar tissue meet in the midline. ● Pus on or expelled from the crypts of the tonsils ● Group A beta-hemolytic streptococcus common on throat culture ● Pharyngeal pain & edema Symptoms of Adenoidal tissue infection: 1. Nasal quality of speech 2. Mouth breathing 3. Difficulty hearing 4. Halitosis 5. Sleep apnea Nursing Implications: ● Instruct the parents about prescribed antipyretics and analgesics. ● Explain the need to complete the full 10-day course of antibiotic therapy, despite improved symptoms. ● ● If tonsillectomy is planned, provide necessary teaching, including the reason why surgery cannot be performed while tonsils are infected. Before surgery, check to be certain that bleeding & clotting times, complete blood count, & urinalysis have been done & that the child does not have loose teeth. check for clotting time - prothrombin time CBC and Urinalysis - to check for infection Following tonsillectomy, position the child on the abdomen with a pillow under the chest to promote drainage from the child’s mouth. prevent aspiration Monitor vital signs frequently to check for signs of hemorrhage, & observe for other subtle signs, such as frequent swallowing, throat clearing, & a feeling of anxiety. given ice cream after anesthesia wears off vasoconstrictor If bleeding does occur, elevate the child’s head & turn him or her on side, & notify the physician. Anticipate a return to surgery if hemorrhage is extreme. If inspiratory stridor, increased respiratory rate, & cyanosis occur, suspect pharyngeal obstruction caused by local bleeding & clot formation, & notify the surgeon immediately. If appropriate, extend the child’s head & neck over the edge of the bed & strike the back sharply to help dislodge the obstruction. same approach with pregnant women (heimlich maneuver) Have suctioning equipment available to clear an obstruction but keep in mind that this procedure may initiate fresh bleeding. suction not on the tonsil removed, sa bungad lang Offer frequent sips of clear liquid or ice chips as soon as the child has completely awakened from the anesthesia. Do not offer dairy products, carbonated beverages, or acid juices. acid is contraindicated Tell the parents to progress to a soft diet in 24 to 48 hours & a selective diet by the second week. depends on the doctor’s order Provide teaching to the parents, including danger signs to watch for, need for activity restriction until after the 7 postoperative danger signs: check subtle signs of hemorrhage above Telephone number to use if they have a question & need to keep a follow-up appointment in approximately 2 weeks. th ● Nursing Diagnosis: ● Risk for deficit fluid volume related to blood loss from surgery. Outcome Evaluation ● Child will maintain adequate fluid volume balance postoperatively. ● Child’s pulse & blood pressure are normal for age group; there is absence of extensive bleeding; intake & output are within acceptable parameters. ● Pain related to surgical procedure. specify pain scale Outcome identification ● Child’s discomfort will be limited to a tolerable level. 27 Outcome evaluation ● Child states that level of pain is tolerable. E. EPISTAXIS Description ● Epistaxis (nosebleed) is extremely common in children. balingoyngoy in tagalog ● It can occur from trauma; lack of humidification; respiratory infection; after strenuous exercise; & in association with a number of systemic diseases; such as rheumatic fever & measles. ● Epistaxis can occur with nasal polyps, sinusitis, & allergic rhinitis. ● There is a familial predisposition to epistaxis. other members of the family experiences it too Assessment Findings: ● Visible bleeding ● Blood in nasopharynx ● Slight choking sensation Nursing Implications: ● POSITION: Keep the child with nosebleed in an upright position w/ their head slightly tilted forward to minimize the amount of blood pressure in nasal vessels & to keep blood moving forward not back into the nasopharynx. ● Apply pressure to the sides of the upper nose with your fingers for about 10 minutes. Ice on Forehead 15 minutes pinch the bony area at the bridge of the nose apply ice cap in forehead as vasoconstrictor ● Calm the child because crying increases pressure in the blood vessels of the head & prolongs bleeding. ● If bleeding continuous: apply epinephrine 1: 1000 to constrict blood vessels & control bleeding as prescribed. ● Assess the need for a nasal pack. ● ● Investigate potential cause in the child who has chronic nosebleeds. Teach parents the importance of keeping the child in an upright position & to apply firm manual pressure for future nosebleeds. F. LARYNGITIS Description ● Laryngitis is inflammation of the larynx, which results in brassy, hoarse voice sounds or inability to make audible voice sounds. Fluimucil can be effective in loss of voice, it may open the airway -> loosens secretion ● It may occur as a spread of pharyngitis or from excessive use of the voice. At risk: singers/teacher signs of Bacterial Laryngitis Assessment Findings: ● Brassy, hoarse voice sounds ● Complaints of annoying tickling sensation ● History of recent pharyngitis Nursing Implications: ● Instruct the parents to offer the child sips of fluid (either cold or warm) to offer relief ● From annoying tickling sensation is often present. ● Tell the parents that the most effective measure is to instruct the child not to talk for at least 24 hours until the inflammation subsides. ● Advise the parents to try & meet the infant’s needs before they have to cry for things; older children simply need to be cautioned not to speak. ● Tell the parents that it is not necessary to have the child on bed rest, & the child will probably use the voice to ask for things if restricted to bed. G. CROUP (LARYNGO-TRACHEOBRONCHITIS) Description ● Croup is an inflammation of the larynx, trachea, & major bronchi, commonly occurring between 6 months & 3 years of age. tuspirina ● Croup is usually caused by a viral infection, such as parainfluenza virus or Haemophilus influenzae. ● Is one of the most frightening disease in early childhood because symptoms of respiratory distress appear so suddenly. ● The danger of croup is the potential for glottal obstruction from the laryngeal inflammation. occludes epiglottis 28 ● Severe symptoms typically may last several hours & subside in the morning, possible recurring the next night. may cause death to a 6-month-old baby ● Assessment Findings: ● Upper respiratory infection at bedtime ● Barking (distinctive harsh brassy) cough during the night ● Inspiratory stridor ● Marked respiratory retractions ● Extreme respiratory distress ● Cyanosis (maybe present) ● ● Nursing Implications: ● Instruct the parents in the home management of symptoms, including filling a room with steam, such as with running a hot shower & bringing the child into the bathroom. heater in bathroom = hot shower, right temperature to prevent scalding new technology: ● ● ● ● ● ● ● ● ● ● ● Inform the parents to transport the child to the emergency department if at –home measure (hot shower) do not abate the child’s symptoms. Apply cool, moist air via an air tent once the child arrives in the emergency room. ● ● ● relieve from stress ● if a bigger child = only until shoulders are covered to assess breathing pattern. (right picture) old mist air tent: plastic canopy ● back: receptacle where ice cubes are [art ● cold mist, and oxygen, while it is melting it will go inside. ● putting a barrier at the back to make sure the mist does not go out. ● there is oxygen at the back (left picture) new mist tent: there is also oxygen at the back Advise the parents to remain constantly with the child for observation & to reduce anxiety. Administer dexamethasone (steroid) to reduce airway edema. Administer racemic epinephrine via Nebulizer for bronchodilation. frequent attack - advised to stock Begin IVT to maintain the child’s hydration status. Offer sips of liquid, if able to take, to maintain hydration & moist secretions. Measure I & O & urine specific gravity to evaluate hydration. Keep the child calm, & do not elicit gag reflex because this can cause laryngospasm with total occlusion of the airway. if inserting tongue depressor don’t go deeper eliciting may block the airway, may cause death Monitor for restlessness, tachycardia, tachypnea, stridor & cyanosis because they indicate increased respiratory distress. Maintain a continuous record of vital signs & activity to assess for increasing respiratory rate & restlessness. Continuously monitor pulse oximetry & transcutaneous PO2 to document if hypoxia is occurring. Obtain arterial blood gases to determine adequate oxygenation if pulse oximetry is not available. Prepare for & assist with tracheotomy or ET intubation if necessary. A tracheotomy is an opening surgically created through the neck into the trachea (windpipe) to allow direct access to the breathing tube. Monitor for associated complications of a tracheotomy such as infection, atelectasis, tracheal tube occlusion, tracheal bleeding, Granulation or stenosis, & delayed stoma healing. otomy - opening ectomy - removal complication of tracheostomy - stenosis (narrows again) -> ET tube is inserted. “earring analogy” Explain the condition of croup to the parents & discuss appropriate care after Discharge, which may include continued use of humidity & assurance of adequate hydration. Inform parents that the croup runs its course in 3-7 days; allow them to verbalize any concerns they may have on returning home. Nursing Diagnosis: ● Ineffective airway clearance related to edema & constriction of airway. Outcome Identification ● Child will demonstrate adequate airway clearance by 1 hour. Outcome Evaluation ● Respiratory rate is below 22 breaths / min; No cyanosis; PO2 is 80-100 mm hg; SaO2 is over 95% ● ● ● H. EPIGLOTTITIS Epiglottitis is an inflammation of the epiglottis most commonly seen in the child age 2 to 8 years. Although rare, epiglottitis creates an emergency situation because the swollen epiglottis prevents the airway from opening. The cause of epiglottitis is either bacterial or viral; Haemophilus influenzae type B is the most common bacterial cause. 29 ● ● ● ● Echovirus & respiratory syncytial virus also cause epiglottitis. The child usually has a history of a mild upper respiratory infection. Inflammation spreads to the epiglottis & severe symptoms develop. Inspection of the edematous epiglottis with a tongue blade can initiate the gag reflex, which can cause complete obstruction. REMEMBER: do not elicit gag reflex when assessing using tongue depressor Assessment Findings: ● Inspiratory stridor ● High fever ● Hoarseness ● Sore throat ● Difficulty swallowing with excessive drooling ● Cherry red, swollen epiglottis ● Leukocytosis Nursing Implications: ● Evaluate all toddlers with epiglottitis symptoms ● Obtain blood cultures for evaluation of septicemia. ● Maintain a patent airway & prepare for insertion of artificial airway if obstruction occurs. ● Prepare the parents & child if a tracheostomy or endotracheal intubation is necessary. ● Never initiate the gag reflex with children with symptoms of epiglottitis unless a means of providing an artificial airway is present. ● Keep the child as calm as possible to avoid precipitation of obstruction. ● Obtain lateral neck-X Ray films to reveal enlarged epiglottitis. ● Explain to the parents & child what epiglottitis is & how serious its manifestations can be. ● Accompany the child on all tests in case obstruction occurs. ● Administer moist air to reduce the epiglottal inflammation. ● Administer oxygen as prescribed if the child is cyanotic. ● Prepare the parents & child for all procedures & orient them to the hospital routine. ● Administer antibiotics intravenously as prescribed, such as cefuroxime or chloramphenicol. ● Administer intravenous fluids for hydration, & monitor intake and output. ● Support families throughout the hospital experience. ● Encourage the parents to stay with the child. ● Prepare the child & the parents for discharge & educate them regarding any restrictions or medications. ● Recommend that parents revive counseling for the child that was not brought to the hospital soon enough & died from complete obstruction. 30 Week 5: Lower Respiratory Tract Disorders OUTLINE LOWER RESPIRATORY TRACT DISORDERS A. Bronchitis B. Bronchiolitis C. Cystic fibrosis D. Asthma E. Complication of Acute Respiratory Infection F. Otitis Media Acute G. Otitis Media Chronic II. Learning Objectives: After lecture / discussion, the students will be able to: 1. Review the anatomy & physiology of the lower respiratory disorders. 2. Identify the different disorders of the upper & lower respiratory disorders 3. Define related terms. 4. Discuss the signs & symptoms of each problem. 5. Explain the Nursing Implications of each disorder. Lower Respiratory Tract: 1. Trachea 2. Primary bronchi a. split into 2 3. right and left lung 4. alveoli left lobe= 2 ● ● ● ● right lobe= 3 A. BRONCHITIS Bronchitis is an inflammation of the major bronchi & the trachea. (occurs during wet season) This inflammation is usually secondary to an upper respiratory tract viral infection, which spreads to the bronchi. It is seen in children under age 2 & more often in the winter. Infants with acute bronchitis can develop acute respiratory distress. ● ● The associated cough is pronounced at night & can wake a child from sleep. The cough may persist for up to 10 days. The child’s sign & symptoms persist for about a week & then fade. Assessment Findings: ● ● ● ● ● ● ● ● ● ● ● Gradual development of a hoarse, hacking, productive cough “Noisy rattling breathing” Wheezing Rhonchi Fine or coarse rales Increased percussion sounds secondary to hyper-inflated alveoli Signs of respiratory distress Fever Leukocytosis Increased erythrocytes sedimentation rate Chest film with diffuse alveolar hyperinflation & hilus markings Nursing Implications: ● Explain to the concerned parents what bronchitis is & that normally the child does not require hospitalization. ● Teach the parents appropriate interventions to relieve the child’s symptoms. ● Have the parents maintain the child on bed rest & provide plenty of fluids. ● Instruct the parents to keep air warm & moist & that a bronchodilator may be prescribed to dilate the bronchi. ● Teach the parents how to use a bronchodilator & also about any antibiotics prescribed if the infecting organism is a bacterium. ● Advise the parents to administer an expectorant if the child’s mucous is viscous. dilute the phlegm ● Recommend against cough syrups because the child’s cough should not be suppressed but encouraged to expectorate accumulating secretions. expectorant not suppressant, only if child can’t sleep ● Keep in mind that cough suppressants may be used at night if the child has trouble sleeping. ● Teach the parents to administer antipyretics, such as acetaminophen, to reduce fever. ● Educate the parents on worsening signs of respiratory dysfunction, & advise them to seek medical attention for their child if they occur or if the child does not improve. can be advised for confinement B. BRONCHIOLITIS Description ● Bronchiolitis refers to an inflammation of the fine bronchioles secondary to an acute respiratory viral infection in children under age 2. ● The peak incidence of bronchiolitis is 6 months. ● Bronchiolitis most commonly occurs during Winter & spring months & occurs in boys more than girls. ● agent: The respiratory syncitial virus (RSV) is the most common underlying cause of bronchiolitis. 31 ● ● ● ● ● ● ● Respiratory syncytial virus, or RSV, is a common respiratory virus that usually causes mild, cold-like symptoms. Transmission: RSV can be spread by respiratory droplet for up to 9 days. less contact, protect other children The inflamed bronchioles become edematous, & respiratory secretions accumulate, occluding the bronchiolar lumen (narrowed) May impair the breathing of the infant The narrowed airways comprise expiration & cause air to be trapped in the alveoli. Hyperinflation occurs followed by atelectasis. Atelectasis, the collapse of part or all of a lung, is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the lung. The inadequate ventilation leads to hypoxemia & hypercapnia. The acute phase of bronchiolitis lasts 2 to 3 days, after which the child’s condition improves rapidly. Many children with numerous instances of bronchiolitis in early life go on to develop asthma. ● ● ● ● Assessment Findings: ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Nasal drainage Sneezing Coughing Poor appetite or inability to suck Risk for confinement due to poor nutrition and dehydration Low-grade infection Tachypnea Nasal flaring Intercostal & subcostal retractions on inspiration Inspiratory crackles Expiratory wheezing Dyspnea Tachycardia Productive or congested cough Cyanosis & hypoxia Low oxygen saturation levels Laboratory analysis of nasal washings positive for RSV Nursing Implications: ● Maintain the child with adequate oxygenation, & institute humidified oxygen therapy if necessary to counteract cyanosis & preserve hydration. ● Prevent spread of the infection with respiratory isolation & good handwashing. before COVID, mask is usually worn for upper respiratory tract infections ● Administer prescribed antibiotic if causative organism is unknown. ● Administer ribavirin by aerosol if the causative organism is RSV. ● Caution the parents about the dangers & teratogenic side effects of this drug. Must know the drug study of each drug to be administered. ● Explain to parents about their child’s condition & about bronchiolitis. To alleviate their anxiety ● Help the parents to understand that this child did not have a simple cold & that they should not feel guilty. ● ● ● ● ● ● ● ● Help the parents to understand that although this can be a life-threatening disorder without treatment, with appropriate treatment, the child will be much better in a few days. if baby does not suck or sustain hydration -> needs confinement for IV therapy Institute fluid therapy to maintain hydration & liquefy secretions. Maintain the child in a semi-fowler’s position to facilitate breathing. rationale: to avoid pressure on the baby’s diaphragm Promote airway clearance via chest physiotherapy because bronchodilators are often ineffective in infants because they have inadequate bronchiole muscles to respond to the drug. CHEST PHYSIOTHERAPY: How to perform to a baby: if bottle feeding, get the tsupon, put in between index and middle finger. Tap the chest/back using the tsupon (bottle nipple). Suction is also done after the phlegm is dislodged. Know where the secretions are located based on x-ray/auscultation (adventitious breath sounds) so that you know where to perform it and dislodge the secretions na nakakapit. When is it done: After the administration of nebulization. It helps loosen secretions and pinapaluwag ang narrowed airway first. Before or after feeding? give prior the feeding if after, suspend for 2 hours first to prevent aspiration. For Bigger babies - cupped hands, cupping technique. Not flat to prevent marks and redness. Institute full respiratory assistance, & assist with extracorporeal membrane Oxygenation if necessary to maintain adequate oxygenation. Maintain adequate nutrition because feeding often increases the work of breathing. Tachypneic - NGT, TPN, IV fluid Administer parenteral or enteral fluids if the child is unable to take oral feedings. Provide sufficient rest periods to help conserve the child’s energy for breathing. especially if after feeding at hapong hapo ang bata (nanghihina) Encourage the parents to verbalize their fears over the illness of their small child. Recommend that parents assist with the care of their child as much as possible. For them to know what to do incase it happen at their own house. (eg: how to perform chest physiotherapy) Explain all procedures & equipment to the parents & support them throughout the hospitalization. Nursing Diagnosis: ● Parental anxiety related to respiratory distress in children. Outcome Identification ● Parents will demonstrate reduced anxiety regarding a child's illness by 24 hours. Outcome Evaluation ● Parents state that their anxiety level is tolerable as S & S of disease decrease. 32 C. CYSTIC FIBROSIS Description ● Organ affected: Lungs and Pancreas ● Cystic fibrosis is a hereditary disorder causing widespread dysfunction of the exocrine glands; it is caused by an autosomal recessive trait that occurs predominantly in whites & affects both sexes equally. ● Mucous secretions of the body, especially the pancreas & lungs, are abnormally thick & have difficulty flowing through gland ducts. ● There is a marked electrolyte change in the secretions of the sweat glands. affected: sodium chloride ● The pathophysiology of cystic fibrosis is the inability to transport small molecules across cell membranes, leading to dehydration of epithelial cells in the airway & pancreas. blocked across cell membrane ● Cystic fibrosis shortens life expectancy; however, with the available option of lung transplantation, life expectancy is increasing. ● This disorder can be found by chorionic villi sampling or amniocentesis early in pregnancy. Chorionic villus sampling (CVS), or chorionic villus biopsy, is a prenatal test that involves taking a sample of tissue from the placenta to test for chromosomal abnormalities and certain other genetic problems. also can be detected in newborn screening within/after 24 hours, should be Breast fed ● Boys with cystic fibrosis may not be able to reproduce because they may have tenacious plugging of the vas deferens. ● Girls may have thick cervical secretions making it difficult for sperm to penetrate. tenacious secretions of the woman blocks the sperm, the sperm cannot meet the egg cell. ● The pancreas of children with cystic fibrosis eventually atrophies from plugged ducts, which causes an increase in back pressure; the pancreatic enzymes are not produced. back pressure can cause pain ● Children are unable to digest fat, protein, & some sugars. ● Initial misdiagnosis in infants of a milk allergy occurs often. ● Infants with cystic fibrosis are not breast-fed because there is not sufficient protein in breast milk for them. The child is given milk formula: probana (formula fed) ● The lungs of children with this disorder plug with thick mucous in the bronchioles causing obstruction, ventilatory problems, & bacterial infection. ● The most frequent lung infections are caused by a. Staphylococcus aureus b. Pseudomonas aeruginosa c. Haemophilus influenzae. ● Cystic fibrosis eventually leads to secondary emphysema with overinflated alveoli accompanied by chronic hypoxia & hypercapnia. overinflation -> emphysema -> hypoxia and hypercapnia ● Atelectasis, bronchiectasis, & pneumonia occur. Assessment Findings: ● Chloride: sodium concentration of sweat 2 to 5 times above normal ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● Feces: o Steatorrhea increase in fat excretion in the stools. o Foul-smelling stool Protuberant abdomen Malnutrition with emaciated extremities Loose flabby folds of skin on the buttocks Fat-soluble vitamin deficiencies Meconium ileus (first obvious sign in infants) Nausea Colicky abdominal pain Decreased breath sounds Hypoxia Hypercapnia build up of carbon dioxide in the bloodstream Fever Productive cough Tachypnea Wheezing Rhonchi Barrel chest Clubbed fingers angle - 180 degrees, normal: 160 degrees Failure to gain back initial weight lost as a newborn by 4 to 6 weeks. factors of weight loss in the first 2 weeks: passing out stool, urine, sweat. poor sucking and hormones. regain weight after 2 weeks Nursing Implications: ● Carefully evaluate for passage of stool & meconium in a newborn. ● Monitor the infant’s weight & note if the child regains initial loss of weight by 4 to 6 weeks. ● Note any child seen at a health visit with complaints from the mother that the child has a feeding problem because the child always appears hungry. (these children absorb only about 50% of their intake & then eat so ravenously that they swallow air, which is then manifested as colic. swallowed too much air -> colic ● Assess type & frequency of stool & whether there is a foul odor with it. ● Note any child seen frequently in the health care setting between 4 & 6 months because of frequent respiratory infections, a chronic cough, & failure to gain weight. ● Support the parents & child through initial tests for o duodenal analysis of pancreatic enzymes o sweat testing to determine sodium chloride values o chest film (xray) to check lungs o pulmonary function tests. To check lung capacity, PFR ● Explain all procedures & answer any questions that the parents may have. ● After confirmation of cystic fibrosis occurs, spend time with the parents to help them understand this multifaceted disease. ● Promote airway clearance, & control respiratory infections & teach the parents the importance of maintaining adequate hydration in this population. ● Provide supplemental high humidity oxygen if prescribed. To moisten the mucous membrane ● Encourage a child on bed rest to make a frequent position every 2 to 4 hours so that all lobes of the lungs drain by being in a superior position. 33 ● ● ● ● ● ● ● mobilizes secretion and prevents stagnation Observe the hospitalized child frequently to assess for rapid deterioration in pulmonary status. oxygen saturation Provide respiratory hygiene & mouth care to aid with the disagreeable taste & odor of secretions. Maintain adequate rest & comfort to avoid exhaustion & ensure that the child is adequately rested before eating. Educate the parents on the use of bronchodilators if prescribed to combat airway narrowing & to help the child expel mucus. Teach the parents how to perform chest physiotherapy & breathing exercises & support them as they begin to realize the lifelong commitment to maintenance of a clear airway. Prepare the parents for the expectation of acute pulmonary infections, which will need to be treated with intravenous & inhaled antibiotic therapy. Instruct the parents on how to promote digestive function in their child. foul odor stool Nutrition-related: ● Place the infant on Probana, a high- protein formula. milk formula prescribed by the doctor Instructions should be based if the child is a breast-fed, milk formula-fed, or solid food-fed baby. ● Place the child on a high-calorie, high-protein, moderate –fat diet. ● Supplement the diet with water-miscible forms of vitamins A, D, & E. ● Inform the parents of the need to add extra salt to food, especially in hot months, because of the excess salt lost in perspiration. ● Instruct parents that medium-chain triglycerides are used with the diet because they are more readily digested than other oils. ● Educate the parents & child that before each meal & snack they need to take a synthetic pancreatic enzyme to replace the enzyme they cannot produce. ● Instruct the parents on the different methods of administering these large capsules. ● ● ● ● ● ● ● ● ● Educate the parents on how to assess for delivery absorption by monitoring their child’s stool & weight. Monitor skin integrity in this population as related to acid stools & frequent periods of prolonged bedrest from pulmonary complications. Provide skin care Assess for rectal prolapse after stools. Observe family dynamics & assess for ineffective or compromised coping. Provide assistance & support to the parents regarding home of these children. Promote a normal childhood & have the child attend regular school if possible. Allow the child to participate in physical fitness activities as tolerated. Ensure that the child has routine health assessments & maintains adequate immunizations Encourage parents to verbalize their frustrations & put them in contact with support agencies such as the Cystic Fibrosis Foundation. Nursing Diagnosis: ● Imbalanced nutrition, less than body requirement, related to inability to digest fat. Outcome Identification ● Child will absorb an adequate nutritional amount daily. Outcome Evaluation ● Child’s height & weight follow percentile growth curves; quantity of stool decreases; S & S of vitamin deficiency are absent. Hyperinflation of the lungs & bronchiectasis in cystic fibrosis D. ASTHMA Description ● Asthma is a chronic disorder characterized by hypersensitivity of the trachea & bronchi. ● It is a leading cause of chronic illness in children, affecting children first between ages 2 & 8 & affecting more boys than girls. ● Incidence: occur initially before age 5 years of age although in the early years it may be diagnosed as frequent occurrences of bronchiolitis rather than asthma. ● A chronic inflammatory disorder of the airways in which many mast cells, eosinophils and T lymphocytes may play a role. ● An allergic manifestation characterized by spasms of the smooth muscles of the bronchi due to edema & overabundance of mucus. spasm - tightening of muscles, constriction ● Tends to occur in children with atrophy or those with a tendency to react with hypersensitivity to allergen. ● Mast cells release histamine & leukotrienes that result in diffuse obstructive & restrictive airway disease because of inflammation, bronchoconstriction, & increased mucus production. ● Asthma results in diffuse pulmonary obstructive disease. ● Associated pathophysiologic responses or mechanisms of the disease include bronchospasm, mucosal edema, & increased accumulated thick bronchial secretions. ● These responses reduce the size of the lumen of the airway leading to distress. ● Factors that may trigger severe bronchoconstriction include inhaled irritants, such as cold air, fumes, smoke, inhalation of known allergen, viral upper respiratory infections, & exercise. swimming is the best exercise ● Bronchoconstriction is the result of stimulation of the parasympathetic nervous system, which initiates smooth muscle constriction. 34 ● ● ● Inflammation occurs because of mast cell activation to release leukotrienes, histamine, & prostaglandins. These cause broncho-constriction & mucus production. Drugs used for asthma aim to control or dilate the bronchiole. antihistamine, corticosteroids, nebulizer Goals for managing asthma include o maintaining airway patency o hydration lots of fluid to dilute/liquefy secretion to expectorate o ventilation open windows, use electric fan ● ● ● ● Assessment Findings: ● Chest tightness ● Dyspnea - difficult to force air into the narrowed lumen of the inflamed bronchioles filled with mucus. ● Decreased breath sounds ● Wheezing on inspiration due to obstruction of airflow in the bronchioles & smaller bronchi. Expiration is prolonged because not all the inspired air can be expired. When severe, it is heard during inspiration. ● Paroxysmal cough ● Thick, copious, mucoid sputum / secretions ● Tachypnea ● Tachycardia ● Cyanosis ● Frightened - due to acute feeling of suffocation ● Sputum analysis with white casts ● Respiratory acidosis - hypercarbia - due to impaired respiration & increased formation of carbonic acidPaCO2 due to bronchospasm. ● Hyper-resonant lungs on percussion - (louder, hollower noise) due to pockets of trapped air behind clogged bronchi. As constriction becomes acute, the wheezing sound may decrease because so little air is leaving the alveoli. ● Expiratory time increased ● Decreased PaO2 - hypoxia- inability to fully aerate the lungs. due to tenacious secretions ● Difficulty speaking ● Respiratory failure - when hypoxemia & cyanosis becomes severe & when blood gases show increased PCO2 level & sound of wheezing stops. due to too much secretions, should be suctioned ● During the attack position in sitting or standing position to open the airway and prevent diaphragm pressure ● Stunted growth - if given long periods of steroids especially if started young in children, epiphyseal bones are just starting to grow. ● Shield-like or barrel shaped chest from constant over inflation of air in the alveoli ● Clubbing of fingers from the growth of excess capillaries initiated when polycythemia is sensed because of poor tissue O2 in distal parts. ● Anxiety & restlessness ● Elevated eosinophil count - suppress the inflammatory response by neutralizing histamine. ● Reduced pulmonary function test ● Excessive perspiration, dilated neck veins Nursing implication: ● Obtain a thorough family history of atopic disease. ● Teach parents about pathology of the disease, normal management, emergency management, medications ● ● ● ● tests: ● ● ● ● ● & their uses & side effects, administration, & how to avoid exposure to allergies. know the allergen to prevent exposure Explain all procedures to the child & encourage parents to stay with the child to allay his fears Suggests skin testing & hypo-sensitization to identified allergens. Radioallergosorbent test (RAST) hypo-sensitization -> eating food you are allergic to in small amounts to desensitize. Use bronchodilators & corticosteroids to maintain a patent airway. Educate parent & child on the dangers of overusing inhalant medication. to prevent overdose, follow interval prescribed by doctor in using nebulizer (eg: every 4 or 6 hours) Teach parents & child use of a spacer tube between the inhaler & the mouthpiece for children under 12 years to ensure proper dose administration from metered inhalants. Monitor for dehydration & teach signs to parents. Administer fluids as necessary to hydrate because an asthmatic child can become dehydrated quickly from insensible losses, decreased oral intake, & diuretic effects of some bronchodilators. Help parents understand the importance of hydration to help thin bronchiolar secretions. Support parents & child to help them understand how to prevent attacks & manage them. Pulmonary function studies - provide an objective & reproducible method of evaluating the presence & degree of lung disease as well as the response to therapy. Peak expiratory flow rate (PEFR) - measures the maximum flow of air that can be forcefully exhaled in 1 second. Measured in liters / minute using a peak expiratory flow meter (PEFM) Skin testing is useful in identifying specific allergens. inhaled: Provocative testing direct exposure of the mucous membrane to a suspected antigen in increasing concentrations, helps to identify inhaled allergens. food: Radioallergosorbent test (RAST) helps identify antigens against various foods & is often useful in determining appropriate therapy. multiple puncturing of the skin to determine food allergies Therapeutic Management: 1. Overall goal is to prevent disability & minimize physical & psychological morbidity- to help the child live a normal & happy life. 2. Allergen control-prevention & reduction of the child’s exposure to airborne allergens & irritants; or eliminate offending allergens; desensitize especially if it is still a young child 3. Maintenance of a physical exercise regimen: a. Teach breathing exercises (deep inhaling and exhaling) b. Blowing pingpong balls helps lengthen expiratory period of respiration c. Reduction of anxiety prevent stress d. At first sign of wheezing, encourage or force fluids to keep mucus thin. liquefy secretions 35 e. Give Cromolyn Sodium before a wheezing attack - for severely asthmatic children to prevent the release of histamines; inhaled through the mouth. ● Management of Acute Attacks- Drug therapy- goal to prevent & control asthma symptoms, reduce the frequency & severity of asthma exacerbations & reverse airflow obstruction. ● Classifications: 1. Long term control medications (preventionmedicines) to achieve & maintain control of inflammation. 2. Quick-relief medications (rescue medications / emergency ) to treat symptoms & exacerbations 3. ● ● Metered`-dose- inhaler (MDI)- nebulizer: ● 6. 7. 8. Cromolyn sodium - is an NSAID for asthma. It stabilizes mast cell membranes, inhibits activation & release of mediator from eosinophil & epithelial cells, & inhibits the acute airway narrowing after exposure to exercise, cold dry air, & sulfur dioxide. B-Adrenergic agonists (albuterol, metaproterenol & terbutaline) for treatment of acute exacerbations & for prevention of exercise- induced bronchospasm. Salmeterol (serevent) long-acting bronchodilator, used 2x a day, anti -inflammatory therapy, used for long term prevention of symptoms at night Methylxanthines –theophylline- relieve symptoms & prevent asthma attacks- central respiratory stimulant & increases respiratory muscle contractility. Leukotriene- mediators of inflammation that cause increases in airway hyper-responsiveness Exercise Chest physiotherapy Hypo-sensitization- seasonal allergies Prognosis is good if they adhere to their treatment regimen. Nursing diagnosis: ● Fear related to sudden onset of asthma attack. Outcome identification ● Parents & child will demonstrate ability to manage sudden attacks within 1 month. long term Outcome Evaluation: ● parents & child express confidence in their ability to prevent attacks & handle any that occur. 4. Nebulization – medication is mixed w/ saline & then nebulized w/ compressed air , breathe normally w/ the mouth open to provide a direct route to the trachea now: no more mixing with saline, at is what is in the nebule Spirometer to measure forcefully she can inhale open the medicine cap put 2 cc of medication in the medication cap mist will get in -> bubbles it is consumed when ubos na ang nilagay na 2 cc 5. Corticosteroids – are inflammatory drugs used to treat reversible airflow obstruction & control symptoms & reduce bronchial hyperactivity. side effects: stunned growth, increased in weight Pulse oximeter - to measure O2 saturation 36 remove manicure and pedicure to determine if nail beds are pinkish or cyanotic ● E. OTITIS MEDIA ACUTE Description ● Acute otitis media is an inflammation of the middle ear. luga in tagalog ● It is the most prevalent disorder of childhood after respiratory tract infections. ● It occurs most often in the child 6 to 36 months of age & again at 4 to 6 years. ● It occurs more frequently in males. ● There is a higher incidence in formula-fed infants because of the more slanted position that formula-fed infants are held while feeding, allowing milk to enter the eustachian tube. propping bottles - bottle propping is when you lean a baby's bottle on a pillow or other support to feed your baby hands-free rather than holding both them and the bottle. danger: spilling of milk, the milk will enter the ear (inside) ● ● ● ● ● ● ● ● If acute otitis media is not treated & cured, permanent damage can occur to middle ear structures, leading to hearing impairment. Assessment Findings ● History of recent respiratory infection ● Red, bulging tympanic membrane ● Fever ● Sharp, constant pain in one or both ears ● Pulling on the ear ● Irritability ● Purulent drainage in external ear canal ● Loss of appetite ● Nasal congestion ● Positive culture & sensitivity for organism Nursing implications: ● Administer antipyretics as prescribed to reduce fever. ● Administer analgesics as prescribed to relieve pain. ● Help the child limit chewing to reduce pain by offering liquids or soft foods. limit giving chewing gum, baka mas sumakit sa eardrum ● Apply local heat or cool compress over the affected ear to minimize pain; encourage the child to prevent pressure on the affected ear by lying on the opposite side. lying on opposite ear to reduce pressure and pain ● If the tympanic membrane has ruptured, place the child on the side of the affected ear in a dependent position to facilitate drainage. ● Keep the external ear clean & dry to prevent skin breakdown. moist area causes bacterial growth ● Assess for hearing impairment & refer for audiometric testing if indicated. to know how much decibels is heard Administer antibiotics, such as ampicillin, erythromycin, gentamycin, amoxicillin, or sulfonamides as prescribed. read the label ● otic - ear drops ● ophthalmic - eyes interval of 10 minutes giving another drug manual of nursing procedures: ● maintain the position for 2-3 minutes. ● position: side-lying position with the ear facing up. If ambulatory, sit with head well tilted to the side. Administer decongestant nose drops as Prescribed to relieve nasal congestion & open up the eustachian tube allowing air to enter the middle ear; caution the parents to administer the nose drops for no more than 3 days because a rebound effect may occur, causing edema & increasing the mucus membrane size. Instruct the parents in the medication regimen, importance or completing entire Prescription of antibiotics, signs of hearing loss, & need for follow-up. Instruct the parents in preventing measures, such as holding the child upright during feeding, gentle nose blowing games, & chewing sugarless gum. do not blow too hard Educate the parents to recognize the signs & symptoms for early diagnosis & treatment. Anticipate the possibility of surgical intervention if chronic otitis media occurs. F. OTITIS MEDIA CHRONIC Description ● Otitis media is inflammation or infection of the middle ear. ● Chronic otitis media is usually caused by gram-negative bacteria, such as Proteus, Klebsiella, & Pseudomonas. ● Chronic otitis media causes serous otitis media. ● The source of air to the middle ear is cut off, & the epithelial cells become secretory cells. ● The middle ear fills with secretions, which are a good medium for infection. ● The fluid becomes thick & tenacious. ● There may be a drop of 20 to 40 decibels in hearing secondary to the fluid. ● Children aged 3 to 10 years of age are most commonly seen with this disorder. Assessment Findings: ● History of chronic ear infections following recent upper respiratory infection. ● Red, bulging tympanic membrane ● Sharp, constant pain in one or both ears ● Purulent drainage in external ear canal ● Fever ● Gradual loss of hearing Nursing implications: ● Maintain careful records & evaluate a child’s history for recent ear infections & treatment. ask recent history of cough and cold, Upper respiratory tract problems or complications 37 ● ● ● ● ● ● ● ● ● ● Educate the parents to recognize the symptoms of acute otitis media & to seek medical attention early for this serious disorder. Refer the child to an ear specialist for further evaluation. Administer antibiotics as prescribed & educate the parents on administering a full dose for pain & fever. Administer analgesics/ antipyretics as prescribed for pain & fever. Encourage the child to lie on the opposite side of the infected ear to decrease pressure. Assess hearing & evaluate for any hearing Impairment. Instruct the parents on the potential need for a myringotomy to allow purulent drainage & to prevent rupture from bulging eardrum. Myringotomy is a procedure to create a hole in the eardrum to allow fluid that is trapped in the middle ear to drain out. Prepare the parents & child for the surgical procedure, usually done in day surgery & requiring general anesthesia. Educate the parents on postoperative care, continued antibiotics or ear drops (or both), & the need to keep water out of the ear during swimming & bathing. depends on doctor’s order if one or both no swimming and bathing because there is dressing and to let it heal Ensure the child & parents have a follow-up appointment. Purulent effusion behind the bulging tympanic membraneotitis media 38
