Nursing Care of the Newborn Newborns undergo many profound physiologic and psychological changes. They are released from a warm, close, dark, liquid filled environment that met all needs, into a chilly, unbound, brightly lit, gravity based, outside world. Within minutes respirations are initiated and circulatory accommodation are made. Within 24 hours neurologic, renal, endocrine, GI, and metabolic functions must operate.

Nursing Care of the Newborn Newborn or neonatal period is the first 28 days of life. 2/3 of deaths occur in the 1st year ½ occur in the 1st 24 hours Assessment Mother’s pregnancy history Physical exam of the newborn Lab reports Bonding

Profile of the Newborn All newborns are different. Vital Statistics Weight: Plot on neonatal graph (Appendix E) Average weight R/T gestational age White female 7.5 lbs.– 3.4 kg. White male 7.7 lbs.-3.5 kg. Other races-0.5 lbs less Limits-5.5 lbs to10 lbs (17 lbs largest) Newborn loses 5 to 10 % of birth weight ( 6 to 10 oz. during first few days.

Profile of the Newborn Loss due to salt and fluid retaining maternal hormones. Voiding and stool, and diuresis. After wt. loss then 1 day of stable wt. then recaptures birth weight within: Breastfed 10 days Formula fed 7 days Will gain 2 lb/month (6 to 8 oz/week) for first 6 months. Length: Female-53 cm.- 20.9 in. Male-54 cm. –21.3 in.

Profile of the Newborn Limits 18 in. to 23 in. Head Circumference: 34 to 35 cm. (13.5 to 14 in.) Limits-less than 33 cm. or greater than 37 cm. Measure with tape drawn across center of forehead and around the most prominent portion of the posterior head.

Profile of the Newborn Chest Circumference: About 2 cm. less than head circumference (0.75 to 1 in.). Measure at level of the nipples. Viral Signs: Temp 99 F at birth Newborns lose heat by: Convection Conduction Radiation Evaporation

Profile of the Newborn They have little subcutaneous fat for insulation. Shivering is rare. They have brown fat – helps to conserve or produce body heat by increasing metabolism. Quickly dry and wrap newborns and place under radiant heat source or place directly against mothers skin. Newborn with a bacterial infection will have a subnormal temperature.

Profile of the Newborn Pulse: Immediately after birth 180 bpm. Within 1 hour- 120 to 140 bpm. Irregular and transient murmurs due to immaturity of the cardiac regulatory center in the medulla and closure of the shunts. Sleeping – 90 to110 bpm. Always check apical for 1 full minute Check femoral pulse for coarctation.

Profile of the Newborn Respiration: 30 to 60 breaths / min. Rate, depth, and rhythm may be irregular with short periods of apnea (without cyanosis) called periodic respirations. Observe movement of the abdomen. Coughing and sneezing clear the airway. Newborns are nose breathers Short periods of crying are beneficial.

Profile of the Newborn Blood Pressure: 80/46 mm Hg at birth 10th day 100/50 mm Hg Cuff 2/3 the length of upper arm or thigh. Physiologic Function Cardiovascular System: Figure 23.3 p. 634 Peripheral circulation is sluggish for 1st 24 hours. Common to see cyanosis of the feet and hands (acrocyanosis) cold to touch.

Profile of the Newborn Blood values: Blood volume-300 mL Increased erythrocyte count-will decrease after 3 days. Breakdown of these cells cause an increase bilirubin >4 mg/100mL At 7 mg/ml tissue is jaundice. Physiological jaundice R/T brusing, cephalhematoma, dehydration, or intestinal obstruction. Treat at 10-12 phototherapy, fluids, >20 neuro kernicterus (permanent cell damage) Hgb 17-18

Profile of the Newborn Hct 45-50% (use warm cloth on heel to increase sluggish circulation to get a more accurate value). WBC increased due to stress of birth. Blood Coagulation: Prolonged coagulation or prothrombin time for 24 hours because of low vitamin K level. Infant intestine is sterile at birth. Administer Vitamin K (AquaMephyton) 1 hour after birth in lateral anterior thigh.

Profile of the Newborn Respiratory: First breath initiated by Cold receptors Lowered PO2 (15 mm Hg) Increased PCO2 (70 mm Hg) Surfactant allows the alveoli to inflate more easily. 1/3 of fluid is forced out of the lungs with the pressure of delivery. Within 10 min. a good residual volume is established.

Profile of the Newborn Gastrointestinal System: Sterile tract for 1st 24 hours Stomach holds 60 to 90 mL Decreased ability to digest fat and starch Regurgitation due to immature cardiac sphincter between stomach and esophagus. Lower glucose and protein serum levels due to immature liver. Stools – meconium 1st 24 hours. Sticky, tarlike, blackish green, odorless.

Profile of the Newborn If no meconium in 24-48 hours possibility of ileus, imperforate anus, or bowel obstruction. Transitional stool- day 2-3 becomes green and loose. Day 4 breastfed will pass 3-4 light yellow stools per day. Bright green is due to increased bilirubin. Watery and loose or mucus may be a milk allergy. Gray clay stool – bile duct obstruction.

Profile of the Newborn Urinary System Voids within 24 hours Light color and odorless; kidneys do not concentrate urine well and no reabsorption. 6 voids /day 15 to 50 mL By 1st week total daily volume is 300 mL Immune System: Unable to form antibodies the 1st 2 months. Has passive immunity from the mother Hepatitis B vaccine during 1st 12 hours.

Appearance of the Newborn Skin Color: Ruddy due to increased concentration of RBC in blood vessels and decreased fat. Fades slightly over the 1st month. Cyanosis-lips, hands, feet Central cyanosis is a great concern Suction mouth before the nose because suctioning the nose may trigger a reflex gasp, possibly leading to aspiration.

Appearance of the Newborn Hyperbilirubinemia leads to jaundice or yellowing of the skin. Occurs on day 2 or 3 in 50% of all newborns due to breakdown of fetal RBC. Indirect bilirubin > 7mg/100 mL Early feeding promotes intestinal movement and helps prevent bilirubin build up. Pallor due to anemia. Excessive blood loss when cord was cut. Inadequate flow of blood from cord into infant at birth.
