OB Unit 4 Care of the Newborn Neonate Term used for a child in the first 4 weeks of life Initial Care & Assessment of the Newborn Immediately After Birth Apgar scoring and vital signs are the first things that the nurse will do following delivery First 24 hours are critical for the newborn. Initial care focuses largely on monitoring and assessing the newborn’s vital signs A. Respiration Secretions are removed w/ bulb syringe immed. Stimulate respirations as needed w/ tactile stimulation The lungs must expand and fill with air on the 1st inspiration. Excess secretions in the airway can cause aspiration pneumonia or death Brief periods of apnea are common for up to 20 seconds at a time. If longer than 20 seconds, the baby needs to be evaluated for apnea Breathing is diaphragmatic and should be effortless. Rate and rhythm will vary with activity Normal respirations are synchronized Chest should expand as a whole Nose breathers Rate is 30-60 breaths/min How does the doctor score my baby? It's easy to remember what's being tested by thinking of the letters in the name "Apgar": Activity, Pulse, Grimace, Appearance, and Respiration. Here's how they're used to rate your baby: Activity (muscle tone) 0 — Limp; no movement 1 — Some flexion of arms and legs 2 — Active motion Pulse (heart rate) 0 — No heart rate 1 — Fewer than 100 beats per minute 2 — At least 100 beats per minute Grimace (reflex response) 0 — No response to airways being suctioned 1 — Grimace during suctioning 2 — Grimace and pull away, cough, or sneeze during suctioning Appearance (color) 1 0 — The baby's whole body is completely bluish-gray or pale 1 — Good color in body with bluish hands or feet 2 — Good color all over 2 Respiration (breathing) 0 — Not breathing 1 — Weak cry; may sound like whimpering, slow or irregular breathing 2 — Good, strong cry; normal rate and effort of breathing B. Apgar Score Assess’ neonates physical condition @ 1 & 5 minutes Evaluates respiratory & cardiac status Refer to pg. 687 Table 25-3 C. Heart Rate Normal is 120-160 beats/min.. Taken apically.. 1 full minute Pulse rate averages with higher and lower variations depending on activity Should have a regular rate and rhythm. Auscultate between the fourth and fifth intercostal spaces. Best done when infant is sleeping. Mumurs are common, MD to determine whether they are significant. Take for one full minute BP averages 60-80 over 40-50 and should be approximately the same in all four extremities.. A drop in systolic BP (about 15 mm hg) in the first hour after birth is common.. D. Provide Warmth (one of nursing’s first concerns) Very susceptible to “cold stress” Maintaining body temp is essential.. Wrap in warmed blanket.. Place cap on head More heat is lost through head than any other body part Newborn has limited amount of protective adipose tissue Neonate’s temperature control center is not fully developed The brown fat is extremely important at this time Place preemies in isolette to keep warm and ensure thermal regulation.. Place on mother’s abdomen Newborn warmer Delay 1st bath until temp is stable (97.6 – 98.6) Protect from drafts Cover work tables and scales so that they are not cold Organize your work so infant is not left uncovered for long periods of time. E. Temperature Normal axillary is 97.6-98.6 .. Temp monitored with skin sensor Rectal temp x 1 following birth Anus MUST be patent • • • • 3 Axillary is most common Be sure temp is 98.6 before bathing F. Identification Done in delivery room 2 ID bands (ankle & wrist) on newborn 1 ID band on mother Foot printing & fingerprinting Double check ID bands before bringing baby to mother At discharge, remove one ID from infant, place in chart, compare it’s numbers with mother’s ID band. Have another nurse sign chart G. Protection of Disease Eye prophylaxis w/ Erythromycin For opthalmia neonatorum Vitamin K injection.. To help with coag factors and prevent hemorrhage Vitamin K Neonates have low prothrombin levels at birth and are at risk for hemorrhage. They are not able to synthesize vitamin K in the colon until they have adequate intestinal flora Best site used for vit K is the Vastus lateralis muscle or thigh.. H. Spine & Extremities Straight without curves Until baby begins to stand Dimples, tufts of hair and masses Single crease in palm of hand AKA Simian line, may indicate Down’s syndrome Simian Crease Equal length of legs Uneven could mean hip dysplasia I. Bonding Promotion of attachment between neonate & family Should begin immediately Bonding The infant is a socially responsive human being Will state intently at parents faces Prefers to look at mother’s eye Can recognize approaching objects Will imitate other’s facial expressions Will reach for objects Recognizes mother’s voice Visual range is 8 – 10 inches Breast feeding should begin ASAP Characteristics of the Normal Newborn A. Weight & Length Weight ranges from 5.5-10 lbs. Length ranges from 18-22 inches Weight Loss Intracellular fluid moves outside the cell (extracellular) adding to babies blood volume, thus increases urine output and baby loses the extra water and drops 5 – 10% of body weight due to H2O loss.. B. Head & Body Lg. Head (13-14”) circumference Short neck Chest smaller than head (12-13”) Large protruding abdomen Head irregularly shaped “molded”.. Caput succedaneum.. Cephalhematoma.. Both resolve on their own Reassure parents C. Fontanels Soft spots Anteriorabove forehead, diamond shaped,closes bet. 18 mos. Posterior@ crown of head, Triangular, closes at 2nd mo. D. Eyes • Blue or gray @ birth.. • Appear cross-eyed, unable to focus • Eyelids red/edematous • No tears • Lacrimal glands are not functioning until 4 months • Eye color established between 6 – 12 months.. Eyes Strabismus (crossed eyes) and nystagmus (abnormal eye motion), are common due to immature nervous system Vision is more acute than previously believed. Newborns can see best at 8-10 inches Prefer simple pictures in black and white and human faces E. Ears Positioned with outer canthus of the eye Low set ears may indicate a chromosomal disorder.. High pitched sounds and mothers voice generate the greatest attention.. F. Skin • Rashes are common • By 3rd day, more natural tone • Acrocyanosis.. • Bluish coloration of hands and feet from poor circulation. Can persist for 7-10 days. • Common when infant is cold Harlequin sign 4 Half of the newborns body appears deep red and the other side of body appears pale as a result of vasomotor disturbance with some vessels constricting while others dilate.. G. Jaundice • Yellow discoloration caused by deposits of bile pigments and also know as icterus neonatorum • First seen on face and mucous membranes • Abnormal during first 24 hours • After 24 hours, it is common • Gradually disappearing by the seventh to tenth day, and caused by the normal reduction in the number of RBCs that are no longer needed for O2 transport • Phototherapy and make sure eyes are covered • Pathological occurs w/i 24 hrs Abnormal • Physiologic May occur in 2-3 days Normal • Immature liver • Elevated bilirubin Treatment Freq. Feeding q 2-3 hrs Sunlight Phototherapy Monitor temp Allow for bonding Influences of Maternal Hormones on Neonate gynecomastia Edematous labia in females Pseudomenstruation.. Bloody vaginal discharge Large scrotum Common Skin Observations IN THE NEWBORN….. Milia 5 Small white spots on nose and chin from clogged sebaceous glands. Disappear within few weeks.. Erythema toxicum Newborn rash, Hive like (Urticarial) Elevated small white vesicles Not contagious Disappears without treatment Stork bites Flat, pink or red marks often seen on eyelids, nose or nape of neck Caused by dilated capillaries that become more vivid when infant cries. Not significant to health of infant Disappears in 1 -2 years Mongolian spots 6 Areas of increased pigmentation. Lumbar dorsal is most common sight May appear bluish black Most often seen in darker skinned persons Port wine stain Reddish purple discoloration often seen on the face Caused by capillary angioma below the epidermis. Will not disappear Petechiae Small, pinpoint hemorrhagic areas under the dermal layer Will disappear unless a coagulopathy is present Vernix caseosa.. Yellowish, white cream cheese like substance Protects infant’s skin from amniotic fluid Lanugo Soft hair Most notable on shoulders, forehead and cheeks Can be found anywhere except soles of hands and feet Various birthmarks Strawberry which are hemangiomas They shrink spontaneously and usually disappear early in childhood Epsteins pearls Small white nodules on the hard palate Caused by epithelial cells and will disappear spontaneously within a few weeks Normal Activities and Reflexes Of the Neonate…. Movement & Activities Sleeps ~ 17 hrs/day Awakens easily Cries when hungry or uncomfortable Arms & legs move freely & symmetrically May startle and make sucking motions during sleep. Breathing may be regular and even or irregular, depending on the sleep state. The time awake is spent crying, eating, or in quiet alertness. Most infants do not exceed 5 continuous hours of sleep for some months Crying is the only means of communication. Can indicate hunger, pain, or simply the need for attention. Cry should be strong, vigorous, and of medium pitch. A high pitched cry may indicate neurological problems and should be observed by M.D. Able to flex extremities Unable to support weight of head Reflexes Rooting Reflex.. Head turns toward direction of stimulus Sucking Reflex Dance or Step Grasp Moro or Startle.. Extension and abduction of extremities followed by embracing motion.. Tonic neck reflex Fencing position Babinski reflex Big toe fans out to side when sole is scraped from heel to toe Newborn movements are jerky due to immature nervous system.. Senses • Smell & Taste • Not a lot is known • There is an increase in sucking with glucose water • They can smell mother’s breast milk Sight Can see shades of light and darkness. Can see best at 8-10 inches Blinks with bright lights Unable to focus Common conditions due to immature CNS Nystagmus Abnormal motion of eyes Strabismus Crossed eyes Hearing Well developed Sensitive to loud noises Encourage parents to talk in soothing voices Can recognize mother’s voice Touch Well developed Responds to discomfort by crying and moving Protection of the Newborn Each neonate is isolated from other babies Specific hand washing & scrub techniques for all persons working in nursery Scrub suits & gowns For all healthcare workers May be used for family members Nurseries are very hazardous places if infections are present People w/ infectious diseases not allowed access Each neonate has own equipment/supplies (never shared) Nursery NEVER left unattended Cribs have clear sides so infant is visible at all times Daily Newborn Care Nursing Assessment 7 1. Vital Signs Respirations Always taken first Chart if baby is awake, crying or sleeping when taken Count for 60 seconds while taking VS, note and make assessment of newborns appearance, behavior, and reflexes Observe abdomen rise & fall Resp. should be quiet , may be irregular Rate ranges from 30-60 breaths/min Pulse Apically for 60 seconds Rapid, may be irregular Normal range is 120-160 beats/min Warm stethoscope first Temperature Use the tympanic method Axillary method as alternative Rectalinsert .5 inch Hold probe at all times What do you need to be aware of at this time? Cover with dry diaper Hold probe at ALL times Temp range97.6-98.6 Hold probe until it beeps Blood pressure Usually low Use smallest cuff Usually placed on leg Range 60-80/40-50 2. Daily Weights Normal to lose 5-10% of birth weight.. Usually regain w/I 10-14 days Weigh daily 3. Eyes, Nose & Ears Report any redness, swelling or discharge 4. Elimination Urination Usually 4-8 hrs fol. delivery Be sure baby voids & document Should have 6-8 wet diapers/day After the 1st 2 or 3 days, the baby voids 5-12 times daily Stools Meconium1st stool Should occur within 24 hours of delivery Dark green, sticky, tarry 8 9 Made up of vernix, strands of lanugo, and other substances from amniotic fluid Transitional stoolgreenish yellow Breast fed stool pale green to golden yellow, smooth, pasty or “seedy” w/ less odor Sometimes passed with each feeding Formula fed stoolbrighter yellow, more formed Should pass two stools per day, then increase to 3 per day after first few weeks If no stool in 24 hours Consider Imperforate anus Inspissated meconium Hardened stool causing bowel obstruction These conditions need surgical intervention 5. Cord Care.. Observe for redness, drainage & sx of infection Cleanse w/ alcohol w/ each diaper change Leave open to dry outside of diaper Avoid getting cord wet (except during first bath) with subsequent bathing Tub bathing is delayed until the fully dried cord drops off at about 10 days Drying process of cord is called mummification Mortification, producing a dry hard mass The cord is an excellent portal of entry for infection until it heals Alcohol reduces the chances of infection 6. Maintaining Warmth Caps Clothing Blankets Warmer Incubator Isolette.. (especially for preemies) 7. Cleansing the Newborn 1st bath after Temp = 98.6 Assess skin color; assess for blemishes, rash, abnormal jerking, twitching, bleeding, or congenital abnormalities during bathing.. Temp of room should be 75 degrees or more Bath quickly and pad all cold surfaces Reassess temp 30 minutes after completion of bath Newborn skin is usually bright red, especially when crying, due to > of RBCs present in blood.. Wipe eyes from inner to outer corner Fol. By face & ears Rinse & dry hair Work from head down Use a non medicated mild soap for initial bath Washing with warm water is sufficient for first week Use mild soap and warm water after each diaper change Vernix is attached to the upper layer of skin Do not vigorously rub You could remove protective skin layer It could be left on for 48 hours Baby’s skin has a pH of 5 soon after birth This slightly acidic skin surface has bacteriostatic effects Therefore, only warm water with a mild soap should be used Alkaline soaps such as Ivory, oils, powder and lotions are not used due to pH altering effect which provides a better environment for bacteria Talcum has added risk of aspiration if applied too close to face Use mild soap sparingly.. Special attention to skin folds Observe for bleeding at circumcision site first 12 hrs.. DO NOT use lotion, petroleum jelly or powder DO NOT wet unhealed cord Treat cord as ordered Dress and wrap in blanket 8. Care of the Penis Only retract foreskin if ordered Very small opening phimosis Smegma secretions that accum. Under foreskin Circumcision Part or all of foreskin is removed Ritual for all Jewish babies Must be kept clean Assess for bleeding, swelling, & voiding Gomco Clamp Sterile petroleum gauze is usually applied after Gomco circumcision and left in place for 24 hours Reapply fresh petroleum gauze after each cleansing with soiled diapers Plastibell Hollister Plastibell Technique No need for petroleum gauze The plastic bell that covers the glans will not stick to diaper Never place on stomach fol. Circumcision Assess q 15 min for 4 hours 9. Sleep Newborns sleep most of the time Except when hungry or uncomfortable Place on side or back No pillows Most do not exceed 5 continuous hours of sleep for some months 10. Holding the Newborn 10 11 Wrap in blanket Support head, neck & buttocks Football hold gives you a free hand 11. Baby’s Responses Cries & tightens muscles in response to sudden, loud noise Crying is only way to ask for help Lusty cry is a strong healthy cry.. Hunger cries are healthy, demanding cries May put fingers in mouth as sign of hunger 12. Infant Feeding Suck & swallow reflexes are present at birth Feed on “demand”.. Every 3-4 hrs Breast fed babies do best on “on demand” schedule (1-3 hour intervals) Bottle fed babies tend to eat less (2-4 hours) because formula is digested more slowly Breastfeeding Colostrum decreases allergies Superior nutrition Economical Readily available Promotes transfer of maternal antibodies 3 Stages of Breast Milk Colostrum.. first substance produced Creamy and yellow white in appearance Contains more protein, minerals, and fat soluble vitamins than mature breast milk Contains high levels of immunoglobulins which transfer some immunity to newborn Transitional Milk.. Milk supply comes in at 3-4 days Transitional milk is produced for about 1 week.. Is thinner and more watery High in fats, lactose, and water soluble vitamins Contains more calories than colostrum Mature Milk Generally established by 2 weeks PP Appears very thin and watery Provides 20 kcal/oz and contains lactose, proteins, minerals, and vitamins Enhances bonding Speeds involution 1st feeding is immed. p birth Best NOT to supplement with bottle Tickle mouth to trigger rooting reflex Entire areola in mouth not just nipple 12 Place finger in mouth to break suction Offer both breast at each feeding Start with breast used last at previous feeding Treat engorgement w/ frequent feeding Diet when breastfeeding Inc. calories by 500/day.. Inc. Milk (1qt./day) Inc. fluids ETOH inhibits let-down reflex & found in breast milk Caffeine is transferred Consult MD re: medications Bottle feeding 1-3 oz per feeding1st wk Total of 15 oz in 24 hrs Intake increases rapidly after 3 wk Always hold infant when feeding.. The first feeding is usually 15 – 30 ml of sterile water to insure infant can swallow normally Do NOT prop bottle Wash hands before & after Right side-lying to prevent regurgitation.. 13. Burping During and after each feeding Done whether breast or bottle feeding Hold upright on knee or against shoulder Important to burp at intervals to remove air from stomach Will increase feeding DISORDERS OF THE NEONATE Group B Strep ( GBS) Life threatening infection Caused by bacterium Common cause of sepsis and meningitis and pneumonia in newborns GBS Before preventative measures were widely used, approximately 8000 babies were stricken each year 1 in 20 babies dies Babies that survived, especially those with meningitis, may have long term problems such as hearing or vision loss or learning disabilities Diagnosis & Treatment Vaginal swab at 35-37 wks Women with +GBS are given antibiotics at time of labor PCN is safe and effective for Mom Erythromycin if allergic to PCN PCN or Ampicillin newborns Most M.D.s do not treat because it may not prevent GBS in newborns unless the GBS is identified in the urine • • • • • • • • 13 GBS in urine should be treated at time of discovery Gestational Age Preterm.. 0 - 37 weeks Problems with hypothermia Keep in isolette Term 38 – 42 weeks Post term 42 or more weeks If the exact gestational age of neonate is unknown, most facilities have assessment procedures to determine age For the first hour the infant is recovering from the stress of birth and this is reflected in muscle movement After 48 hours, some responses change significantly Highest death rate is within first 28 days Gestational Size A.G.A. (Appropriate for Gestational Age) Weight between 10th and 90th percentile S.G.A. (Small for Gestational Age) Below 10th percentile L.G.A. (Large for Gestational Age) Above 90th percentile (DM moms) L.B.W. (Low Birth Weight) Less than 2500 gms Normal is 5.8 to 8.5 pounds The SGA infant may be a result of problems occurring during the first trimester, such as infections or chromosomal abnormalities or a later reduction in the fetal O2 supply or nutrition as a result of smoking ,hypertension or malnutrition Problems could be asphyxia, meconium aspiration syndrome, hypoglycemia, and hypothermia LGA infants have hypoglycemia, resp distress, birth injuries and asphyxia Nursing Considerations With Preterm Neonates Conserve Energy Handle as little as possible.. Delay bathing Special care to keep warm Heat Conservation Lack of subcutaneous fat, large surface area relative to body weight, and poor reserves of glucose and brown fat (source of heat unique to neonates that is capable of greater thermogenic (heat producing) activity than ordinary fat), all contribute to problems with heat conservation Feeding No food for 36 hrs 14 Very small amounts on a 2-3 hr Reflexes may be weak or absent.. Gavage (NG) or expressed milk using a nipple.. The digestive system is formed, but problems with absorption of nutrients are common. Could cause distention Gag, suck, and swallow reflexes may be absent or atypical Elimination Kidneys not fully developed Weigh diaper before & after they urinate The renal system is immature and ineffective Fluid and acid/base imbalance is frequently observed Color and Skin Ruddy Cyanotic Very thin, translucent skin Obvious blood vessels and little sub-q fat Respiratory Status Nasal flaring Retractions of sternum and intercostal muscles Grunting Air hunger All common due to insufficient amounts of surfactant Infection Prevention Good handwashing Contacts with people other than parents is limited Special Care Nursery Respiratory Distress Syndrome (RDS) Leading cause of death Inadequate oxygenation Cause of RDS is unknown Deficiency in pulmonary surfactant Atelectasis is common RDS Major cause of M/M in the neonate period. Occurs almost exclusively in the preterm and LBW infant More often in males and C/S babies Other factors DM moms, asphyxia, maternal hemorrhage and shock Surfactant Deficiency Surfactant reduces surface tension of fluids that line the alveoli, thereby permitting expansion of the lungs and alveolar inflation Without surfactant the lungs are unable to stay inflated and the alveoli collapse at the end of expiration resulting in Hypoxia Atelectasis Respiratory acidosis 15 Symptoms Dyspnea Cyanosis tachypnea Flaring nares Chest retractions Tachycardia Expiratory grunt Low body temperature In severe cases, infants may die within hours of onset of symptoms. Those who survive, show improvement by the 4th day Dx based on X-rays, ABGs, clinical assessment Treatment Oxygen & humidity Antibiotics Exogenous pulmonary surfactant.. Corticosteroids Minimal handling.. RDS Tx directed at correcting imbalances O2 therapy continually monitored Exogenous surfactant administered via ETT shortly after birth Betamethasone to the mother pre-delivery may increase surfactant levels in preemie Survival beyond 96 hours indicates good survival potential Newborns fed via gavage or central line to prevent aspiration Retrolental Fibroplasia.. Often led to blindness in preterm newborns Occurs when oxygen concentration is > 40 % for long periods of time Monitor Oxygen bld levels.. Excessive O2 levels must be avoided Potential Complications of High Risk Newborns Meconium/Amniotic Fluid Aspiration In hypoxic fetus, anal sphincter relaxes meconium passes into amniotic fluid Can occur in utero or @birth If first breath is taken prior to suctioning aspiration Aspirated fluid Can lead to : Atelectasis Pneumonia Pulmonary problems Treatment Oxygen Encourage fluids 16 Regulate temperature antibiotics Cyanosis Blue or dusky color At least 5 Gms of hemoglobin are not combined with O2 Happens very quickly Caused by: Prolapsed cord during delivery Congenital heart defect Medications (analgesics) Treatment is Crucial and must be Prompt Suction Oxygen Postural drainage Rub back GI Disturbances Vomiting, Diarrhea Dehydration Vomiting Congenital defects Birth injury Intracranial hemorrhage Infection Distinct difference between Vomiting & spitting up Diarrhea Most commonly caused by bacteria May be formula or an allergy Stool is formless, greenish-yellow & foul smelling Isolate baby Obtain stool cultures Dehydration can occur quickly Leads to electrolyte imbalance Treat quickly w/ IV, and oxygen Treatment must be immediate or infant will die Necrotizing Enterocolitis Bowel wall necrose & die Common in preterm babies especially if early ROM of if infant suffered from anoxia SX: lethargy, abd.
