Learning Outcomes

  1. Describe the physiology and pathophysiology of selected neonatal complications.
  2. Identify critical assessment and nursing care for neonates with complications.
  3. Develop a discharge plan for these neonates.
  4. Describe the loss and grief process of parents whose infant has died.

Nursing diagnoses: impaired gas exchange (surfactant deficiency, immature lungs); ineffective airway clearance (meconium); ineffective thermoregulation; imbalanced nutrition; risk for infection; pain; risk for injury (hypoxia, oxygen toxicity, drugs, birth trauma, hypoglycemia, kernicterus); ineffective family coping; grieving; impaired attachment from separation.

I. Overview

II. Preterm Neonates

Classification by gestation:

Classification by birth weight (regardless of age):

Risk factors for preterm birth (Table 17-1): previous preterm birth, multiples, uterine or cervical anomalies, age under 17 or over 35, unplanned pregnancy, low socioeconomic status, race, short interpregnancy interval, PROM, IVF, second- or third-trimester bleeding, low or high prepregnancy weight, hypertension, diabetes, infections and STIs, substance use, smoking, long hours standing, late or no prenatal care, toxins.

Common complications: RDS, BPD, PDA, IVH, NEC, ROP.

Assessment findings:

Medical management:

Clinical Judgment, signs of respiratory distress (most NICU admissions are respiratory): audible expiratory grunting (air forced past a partly closed glottis), nasal flaring, retractions (sternal, subcostal, intercostal), duskiness or cyanosis, tachypnea over 60.

Critical Component, neutral thermal environment:

Nursing actions for preterm neonates:

III. Respiratory Distress Syndrome (RDS)

Fetal lung maturity tests:

Assessment:

Complications: PDA, pneumothorax, BPD, pulmonary edema, hypotension, anemia, oliguria, hypoglycemia, calcium and sodium changes, ROP, seizures, IVH.

Medical management:

Surfactant replacement therapy:

Nursing actions:

IV. Bronchopulmonary Dysplasia (BPD)

V. Patent Ductus Arteriosus (PDA)

VI. Intraventricular Hemorrhage (IVH)

VII. Necrotizing Enterocolitis (NEC)

VIII. Retinopathy of Prematurity (ROP)

IX. Postmature Neonates

X. Meconium Aspiration Syndrome (MAS)

XI. Persistent Pulmonary Hypertension of the Newborn (PPHN)

XII. SGA and IUGR

XIII. LGA and Infants of Diabetic Mothers (IDM)

LGA: weight over the 90th percentile; macrosomia = over 4,000 g. Maternal diabetes is the leading cause.

IDM:

XIV. Hyperbilirubinemia

Physiological jaundice (after 24 hours, first week) causes:

Pathological jaundice:

Risk factors: American Indian, East Asian or Mediterranean descent; ABO incompatibility (mother O, infant A or B); Rh incompatibility (mother negative, infant positive); breastfeeding; maternal diabetes; oxytocin or bupivacaine in labor; delayed cord clamping; hypoxia, acidosis, temperature instability; delayed or infrequent feeding; prematurity; excessive weight loss; bruising or cephalohematoma; G6PD deficiency; infection (TORCH); sibling with jaundice.

Table 17-2:

Breastfeeding-associated jaundice Breast milk jaundice
EARLY onset (first few days) LATE onset (after the first week), peaks at 2 weeks
Ineffective breastfeeding, dehydration, delayed meconium (more reabsorption) Breast milk composition increases enterohepatic circulation
Treatment: early effective breastfeeding 8 to 12 times a day; NO glucose water; supplement with pumped milk or formula if intake poor, weight loss excessive or dehydrated Usually continue breastfeeding; if very high, interrupt for a few days of formula then resume; if beyond 2 weeks, check direct bilirubin and TSB for cholestasis

XV. Central Nervous System Injuries

Table 17-3, intracranial hemorrhages:

Type Cause Signs Prognosis
Subdural Tear of the dura over the cerebellum or hemispheres (falx, tentorium, vein of Galen); breech, difficult forceps, excessive molding Symptoms may be delayed 24 hours, then seizures, decreased consciousness, asymmetric motor function, full fontanel, irritability, facial paralysis Hydrocephalus; mortality 45%
Subarachnoid MOST COMMON neonatal intracranial hemorrhage; venous bleeding; trauma (term) or hypoxia (preterm) Often none; seizures starting day 2; apnea in preterm 90% with seizures have normal follow-up
Intracerebellar Primary bleeding or extension; more in preterm LBW; hypoxic insult, vitamin K deficiency Within 2 days to 3 weeks: apnea, bradycardia, falling Hct, bloody CSF, respiratory problems Poorer in preterm; neuro deficits probable

Critical Component, HYPOXIC-ISCHEMIC ENCEPHALOPATHY (HIE):

XVI. Neonatal Infection and Sepsis

Table 17-4 risk factors: maternal (poor nutrition, low SES, substance use, STI history, no prenatal care, PROM over 12 to 18 hours, GBS colonization, chorioamnionitis, intrapartum fever, preterm labor, UTI, invasive procedures, fetal scalp electrode, maternal or fetal tachycardia); neonatal (prematurity, under 2,500 g, difficult delivery, asphyxia, meconium, resuscitation, anomalies, Black, male, multiples); environmental (long stay, invasive procedures, humidified incubators or ventilators, routine broad-spectrum antibiotics).

Critical Component, congenital Zika: mosquito or sexual transmission, crosses the placenta; 5% to 10% of infected pregnancies have birth defects. Congenital Zika syndrome: severe MICROCEPHALY with partly collapsed skull, decreased brain tissue with calcifications, macular scarring, contractures (clubfoot), hypertonia. Test symptomatic pregnant women with travel exposure; routine testing of asymptomatic women not recommended.

Group B Streptococcus (GBS):

COVID-19 (SARS-CoV-2):

Signs of neonatal infection (Table 17-5):

Labs suggesting infection: WBC over 20,000 or under 1,750; neutrophilia; NEUTROPENIA under 1,800 (strongly predictive); I/T ratio over 0.20 (“left shift”); platelets under 100,000. Definitive diagnosis only by positive BLOOD culture; also urine and CSF cultures; serial CRP (8 to 24 hours after birth and 24 hours later); PCR; procalcitonin.

Treatment: ampicillin plus an aminoglycoside (gentamicin) after cultures; stop after 36 to 48 hours if cultures negative; 10 to 14 days for confirmed sepsis, 21 days for meningitis; antivirals or antifungals as needed; dosing by weight, gestational and postnatal age, and liver and kidney function.

Nursing: review maternal history (GBS); VS, I&O, weight; watch for signs and notify the provider early; respiratory support; glucose and electrolytes; assist with LP (hold flexed and still); antibiotics on time; hand hygiene and isolation precautions; inform parents.

XVII. Neonatal Abstinence Syndrome (NAS) and Prenatal Substance Exposure

Opioids (heroin, methadone, morphine, oxycodone, fentanyl):

Cocaine: decreased placental flow, fetal hypoxemia, maternal hypertension; miscarriage, stillbirth, ABRUPTION, preterm labor, growth restriction; neonatal irritability, tremors, high-pitched cry, hyperreflexia, frantic fist sucking, feeding problems, sneezing, tachypnea, poor sleep; long-term growth, attention, language, motor and reasoning problems.

Alcohol: teratogen; miscarriage, preterm birth, SGA, stillbirth. FETAL ALCOHOL SPECTRUM DISORDER with heavy use (about 15 per 10,000 exposed births): irritability, tone changes, tremors, seizures; later low IQ, learning disability, speech delay, attention problems, hyperactivity, poor coordination; facial features: MICROCEPHALY, small eyes, SHORT PALPEBRAL FISSURES, poorly developed PHILTRUM, THIN UPPER LIP, hypoplastic maxilla.

Nicotine: previa, abruption, PROM, preterm birth, LBW, oral clefts, SIDS (all household members should quit), lung function, obesity. SSRIs: possible anxiety, autism, language and executive function effects.

Critical Component, signs of neonatal withdrawal: apnea, diarrhea or loose stools, excessive and HIGH-PITCHED crying, excoriated skin, fever, hyperreflexia, hypertonia, increased rooting and FRANTIC sucking, irritability, tearing, nasal stuffiness, SNEEZING, poor uncoordinated feeding, seizures, mottling, poor sleep, sweating, tachypnea, TREMORS, vomiting, poor weight gain, YAWNING, hiccups.

XIX. Regional Transport and Discharge Planning

Transport: stabilize first; skilled team; maintain temperature, respiratory support and IV therapy; monitor VS, SpO2, glucose, pain; developmental care (eye and ear protection, gel mattress, positioning).

Discharge:

XX. Psychosocial Needs and Grief

Parents of NICU infants: grieve the ideal baby; going home without the baby is devastating; delayed attachment (risk of abuse and neglect), maternal guilt, emotional distancing for fear of death, anger, disappointment, disrupted family life.

Nursing: orient to the NICU and equipment; build trust and ask how they are coping; clear updates; invite questions and calls; involve in care; encourage touch and holding; pumping and milk storage; private space to breastfeed; photos; praise; support groups.
