NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at o o o o RISK FACTORS THAT COULD LEAD ILLNESSES TO A NEWBORN Age- younger or older than ave. Maternal age Concurrent disease- diabetes = infants is often larger than others, as a result this will make delivery harder and increase the risk of nerve injuries or other trauma. Cesarean most likely to happen. Pregnancy complication Placenta previa ( the placenta partially or totally covers the mother's cervix= severe bleeding during pregnancy or delivery) Olygohydramnous- below 300 ml of amniotic fluid= renal agenesis Polyhydramnous - excessive accumulation of amniotic fluid= esophageal atrasia (The esophagus of the baby does not developed properly) Long funis- cord colapse, can coil around the neck (nuchak cord) Vasa previa- some blood vessels that connects the umbilical cord to the placenta lie over near the entrance to the birth canal, when the membranes around the blood vessles rupture the blood vessel also ruptures cause the baby to lose a lot of blood. Small placenta= IUGR, utero placental insuf. Placental infarcts= thrombosis Lifestyle- drug abuse Dysmature- a newborns whose birthweight is innapropriately low for gestational age Whether preterm, term, posterm they are at risk for complications at birth or in the first few days of life. NURSING PROCESS FOR INFANTS Assessment Assess for obvious congenital anomaly Gestational age (the no. Of weeks the baby remained in the uterus) For assessing infants who is at high risk needs there is used of some equipment- cardiac, oxygen, apnea saturation, blood pressure monitoring. Nursing Diagnosis Ineffective airway clearance related to presence of mucus or amniotic fluid in the airway Ineffective tissue oxygenation related to difficulty in breathing Ineffective thermoregulation related to immature status Note: insulator doesn't allow heat to pass conductor allow heat to pass Risk for deficient fluid volume related to insensible water loss Note; Insensible fluid loss is the amount of fluid loss dai;y that is not easily measured (from respiratory system, skin, water in the excreted stool Risk for imbalanced Nutrition, less that body requirements related to lack of strength in effective sucking Risk for infection related to lowered immune response due to prematurity Risk for impaired parenting related to illness in newborn at birth Deficient diversional activity (lack of stimulation) related to illness at birth. NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at Readiness for developmental care to decrease overstimulation easily caused by necessary lifesaving procedures. Outcome Identification and Planning. A goal that implies total recovery from an ilness Individualized care consider newborn's developmental level, physiologic strength, weakness and needs. Implementation Focus on conserving the baby's energy and provide thermoneutral environment to prevent exhaustion and hypothermia. The caregiver must be consistent in caring. Outcome evaluation Infants maintains patent airway Infants demonstrate an ability to suck effectively Infant tolerates procedures without experiencing apnea, bradychardia, and oxygen desaturation. Infants demonstrate growth and development appropriately for gestational age, birth weight, and condition NEWBORNS PRIOTIES IN THE FIRST DAYS OF LIFE 1. Initiating and maintaining respiration. Infant who has difficulty in accomplishing effective breathing = residual neurologic morbidities = cerebral hypoxia Respiratory acidosis- when the lungs can't removed all the carbon dioxide the body produces= body fluids, blood becomes too acidic = hypoventilation Respiratory Alkalosis- decreased in carbon dioxide = hyperventilation. This can be acute or chronic. Establishing respiration must be started immediately after birth to prevent severe acidosis. Asphyxia- lack of oxygen or blood flow in the brain Asphyxia (does not received oxygen when born) in the utero could from cord compression, maternal anesthesia, placenta previa ,premature separation of placenta = respiratory acidosis at birth may have difficulty in the first 2 min of life. Struggling to breath and ciculate blood the infant is forced to used serum glucosed quickly so may become hypoglycemic. Resuscutation is important to infants who fail to take the first breath and for those who have difficulty in maintaning adequate respirations. Factors predisposing infants to respiratory Difficulty in first days of life Low birth weight Maternal History of diabetes Cord prolapse ( unborn baby's umbilical cord slips through the cervix and into the vagina after a mother's water breaks ) Lowered apgar score (<7) at 1 or 5 min. Breech birth Chest, heart or respiratory anomalies NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at RESUSCITATION Establish airway Expand lungs Initiate and maintain effective ventilation Chest compression - id respiratory depression becomes severe that newborn's heart begin to fail. Airway Warming Drying and stimulating the baby (rubbing the back = these two is enough to initiate breathing for a term baby o If newborn does not initiate spontaneous breathing after gentle stimulation: Placed infant under radiant heat warmer in sniffing position and rub the back Assess precordial pulse (heart), pulse oximetry (oxygen saturation) o If newborn is not breathing or the heart rate is less that 100 beats/min: Positive pressure ventilation (respiratory therapy involves delivery of air or mixture of oxygen combined with other gases) = respiration, strong heart beat,color, muscle tone and reflexes will improve. o If there is obstruction in the newborn's airway: Mechanical Suctioning o Still no effort at spontaneous respirations after initial steps: Endotracheal tube o PRIMARY APNEA Infant will respond to stimulation by re-initation breathing o SECONDARY APNEA Asphyxia continues, regular gasping, respiratory efforts slowly decrease and then cease. o Used of LARYNGOSCOPE and ENDOTRACHEAL TUBE Lung Expansion o Well newborns expand their lungs independently with a first breath o The sound of the baby crying is a sign that there is good lung expansion because vocal sound are produced by free flow of air over the vocal cords o Use of bag and mask if infants needs air or oxygen o Air (or oxygen if needed ) = administered at rate of 40 -60 ventilations/min. o Oxygen must be warmed (89.6 f- 93.2f or 32 -34 C) o Oxygen must be humidified (60 - 80%) o Pressure needed to open lung alveoli for the first time = 40 cm H20 -------> 15- 20 cm H20 (adequate to continue inflating the alveoli. o Be certain to listen to both lungs to verify that both lungs are being aerated. o Make sure the correct placement of the endotracheal tube in the trachea not in the esophagus NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at Drug Therapy o Naloxone o Epinephrine (IV) 1:10,000 action: stimulate the heart action o Surfactant- preterm infants might received surfactant to replace the natural surfactant that has not yet formed in their lungs Ventilation Maintenance o Placed infant in radiant warmer (removed clothes except the diaphers) in supine position (15 degrees) because it allows the abdominal contents to fall away from the diaphram. 2. Establishing extrauterine circulation Lack of cardiac function may developed if respiratory function can not be quickly initiated. Audible heartbeat and heartbeat below 60 chest compression should be started (at the lower third of the sternum, 1-2 cm depth, 100 times/min) Heart rate of greater that 60 but less than 100 beats/min no need for compression but continue the ventilation process to facilitate breathing Pulse oximetry evaluate the cardiac efficiency of the newborn (pulse rate) and respiration function (oxygen saturation) Administer epinephrine to stimulate heart action) if the newborn's heart rate is not greater than 60 beats min. After atleast 30 sec. Of performing positive pressure ventilation. 3. Maintaining Fluid and Electrolyte balance After initial resuscitation = will result in hypoglycemia because of the effort of newborn expended to begin breathing. Dehydration = increased insensible water loss cause by rapid respirations. Infant with hypoglycemia- treatment: 10 % dextrose in water to restore blood glucose level. Fluid such as: dillute mixute of dextrose and saline in water (used to maintain glucose, fluid levels and electrolytes) o Soduim, additional glucose, potasium may be added Monitor rate of fluid administration conscientioisly in high risk newborm: fluid overload might happen = patent ductus arteriousus or heart failure. How to monitor fluid status? Measure the: o Urine output- Normal level- 1.5-2 ml/kg /hr o Urine specific gravity- Normal level= 1.005- 1.030 Meaning: it is the concetration of all chemicals i the urine. *pag masyadong mataas ang USG (>1.030) ibig sabihin dehaydrated yung patient or it suggest inaadequate fluid intake. Hypovolemia o Low levels of blood or fluids in the body. o present immediately after birth o Cause is fetal blood loss from condition placenta previa or twin to twin tranfusion o Signs and symptoms NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at Tachypnea Pallor Tachycardia Decreased arterial blood pressure Decreased central venous pressure Decreased tissue perfusion of peripheral tissue Metabolic acidosis Normal hematocrit o ISOTONIC SOLUTION (normal saline)- use to increase blood volume. o Vasopressor (ex. Dopamine) - used to increased blood pressure and improve cell perfusion. 4. Regulating Temperature Important to keep newborn in a neutral- temperature environment = to maintain a minimal metabolic rate essential to effective body functioning. Too HOT environment = Forced to decreased metabolism to their body. Too COLD environment = they must increase their metabolism to warm body cells = INCREASED IN METABOLISM = it calls for increased oxygen. = without oxygen because of respiratory difficulty = body cells become HYPOXIC. HYPOXIC BODY CELLS = When the infants body become hypoxic - vasocontriction of peripheral blood vessles so blood can be pushed into the central torso. If this process continues for a long time = pulmonary vessles constrict and pulmonary perfusion decreases = Infant's PO2 Level will fall and PCO2 level will increase. Note: lowered PO2 level causes fetal shunts such as Ductus arteriosus to remain open = Surfactant production can halt as well = The infant's body will undergo ANAEROBIC GLYCOLYSIS when the environment is too cold = increased metabolism = this process pours acid into the bloodstream = Infant's will be more acidic = risk of acute bilirubin encephalophaty or kernicterus . = Kernicterus : accumulation of unconjugated bilirubin into the brain cells. In short, COLD ENVIRONMENT will result in compromasing: = heart action = breathing = electrolyte balnce = brain function (possibly) Intervention to regulate temp. o Covering cap o Wiping the body and head with dried towel NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at o Using Radiant warmer or prewarmed incubator o Skin to skin contact. Normal Infant Temp. = 36. 5 degree C - 37. 5 degree C ( 97.8 - 99.5 degree F) NOTE! over weight people sweat more profusely than normal-weight individuals because fat acts as an insulator that raises core temperature. Sweating is a natural process to maintain your body temperature, due to the excess layer of fat, your body temperature is higher than that of a thin individual. Hence, to maintain the temperature, your body produce more sweat. RADIANT HEAT WARMER o o o Open beds that have an attached overhead source of radiant heat. There's a probe that register the baby's temperature. The probe is place in the abdomen bet. Infant umbilicus and xyphoid process. Note: do not place on the underside, not over the liver , not overt the rib cage = false readings INCUBATORS o o o Provide warmth and visual observation of the baby. The temp. Of the incubators varies with the amount of time the partholes remain open. The acrylic shield inside the incubator helps to prevent radiation or convection heat loss NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at o o Has probe also. Portholes must remain closed to keep the servo control operating efficiently. If infants become medically stabile and old enough to maintain steady body temp. o Infant can be weaned from the incubator o Dress the infant o Then set the incubator about 1.2 degree C (2 degree F) below the infant temperature. o After half an hour infant still able to maintain steady temp. Lower again the incubator temp. Another 1.2 degree C (2 degree F) continue until the room temp is reach. Skin to skin contact Kangaroo care To maintain body heat 5. Establishing adequate Nutritional Intake. Infants who experienced ASPHYXIA at birth received INTRAVENOUS FLUID o To prevent exhaustion due to sucking o To prevent NECROTIZING ENTEROCOLITS (temporary reduction of oxygen to the bowel) Gavage Feeding (nose to stomach- nasogastirc): o This is introduce to infant's who's respiratory rate remains so rapid and result in ineffective sucking. o Can be use to deliver breast milk from the mother to her baby. Gastrostomy: use for long term nutrition. Benefits of Breast milk: o Immune Protection Use of Pacifier - helps to developed sucking reflex. Infants who can't use pacifier because they must no swallow air, such as those with TRACHEOESOPHAGEAL FISTULA awaiting surgery Gastronomy and gavage feeding needs oral stimulation 6. Establishing waste elimination Immature infant void later than term infants because of the result in all procedures for resuscitation Document any voidings that occur during resuscitation because this is a proof that hypotension is improving and kidneys are being perfused. Immature infants may pass stool later than the term infant because the meconium does not yet reached the end of the intestine at birth. 7. Preventing Infections Contracting an infection = drastically complicate high risk newborn's ability to adjust in extrauterine life increasing metabolic oxygen demand = stressing immature immune system = lowering defense mechanism protection CYTOMEGALOVIRUS - common virus that affects infants during intrauterine life. Infection = NCM 109- Care of the Mother, Child at Risk or with Problems (Acute or Chronic) NCM 109- Care of the Mother, Child at - CMV can cause mononucleosis or hepatitis (liver problem) - Babies born with CMV can have brain, liver, spleen, lung, and growth problems. TOXOPLASMOSIS VIRUS - common virus that affects infants during intrauterine life. - Most babies born with toxoplasmosis have no symptoms. Symptoms can include eye infections, swollen glands, liver or spleen, or jaundice. Staphylococcus Aureus, Enterobacteria, Candiad - hospital acquired infections PREVENTIONS: Hand washing technique and standard precautions 8. Establishing Parent infant Bonding Informed the parents about what is happening during resuscitation at birth Urge the parents to spend as much as time with infants Be certain parent have continuing access to healthcare personnel after discharge.
