Chapter 25

• A high-risk neonate is defined as a newborn, regardless of gestational age or birth weight, who has a greater-than-average chance of morbidity or mortality.

• High-risk newborns are categorized according to five main criteria:

  • Birth weight and gestational age

  • Birth trauma

  • Maternal substance abuse

  • Infection

  • Congenital anomalies

The Neonatal Intensive Care Unit (NICU) Environment & Stabilization

• NICUs are classified into three levels of care:

  • Level I: Basic neonatal care for low-risk infants.

  • Level II: Specialty care for moderately ill or preterm infants.

  • Level III: Subspecialty intensive care for critically ill neonates.

• The NICU environment can be overwhelming and frightening for parents. Key nursing interventions to support parents include:

  • Arranging a NICU tour prior to delivery when a high-risk birth is anticipated.

  • Providing detailed information regarding unit visiting hours, monitoring equipment, and contact procedures.

  • Encouraging parents to provide Kangaroo Care (skin-to-skin holding) and participate in daily care activities as the baby stabilizes.

• Neonatal transport teams utilize the S.T.A.B.L.E. Program framework to stabilize high-risk newborns prior to and during transport to specialized facilities:

  • S - Sugar: Maintain target blood glucose levels.

  • T - Temperature: Prevent thermal instability and cold stress.

  • A - Airway: Establish and maintain adequate airway and ventilation.

  • B - Blood Pressure: Monitor and support cardiovascular stability.

  • L - Lab work: Evaluate complete blood count, blood gases, electrolytes, and cultures.

  • E - Emotional support: Assist parents and family coping with neonatal crisis.

Comprehensive Nursing Care of the High-Risk Newborn

• Respiratory Support:

  • Primary priority is to establish and maintain adequate respirations.

  • Interventions include supplemental oxygen, humidified oxygen hoods, continuous positive airway pressure (CPAP), mechanical ventilation, or extracorporeal membrane oxygenation (ECMO).

• Thermoregulation:

  • Maintain thermal stability within a neutral thermal environment (NTE) to minimize oxygen and glucose consumption.

  • Interventions include double-walled incubators, radiant warmers, warm packs (never placed directly against skin), and skin-to-skin Kangaroo Care.

• Infection Control & Skin Care:

  • Strict adherence to Standard Precautions, meticulous hand hygiene, and delicate skin care to preserve epidermal barrier integrity.

• Cardiovascular Monitoring & Blood Pressure:

  • Baseline neonatal blood pressure is typically around $60/40\,\text{mmHg}$.

  • Mean Arterial Pressure (MAP) must be monitored closely using an appropriately sized blood pressure cuff.

  • Preterm and low-birth-weight infants are highly prone to hypotension; normal systolic BP should be maintained above $50\,\text{mmHg}$.

  • Four-extremity blood pressures are required if a cardiac murmur is detected. A systolic pressure difference of $15\,\text{mmHg}$ or higher between the upper and lower extremities indicates coarctation of the aorta.

• Nutritional & Fluid Management:

  • Parenteral Fluid Therapy: Infused to preserve tissue perfusion and maintain a normal urine output of $1 - 3\,\text{mL/kg/hr}$ (monitored via indwelling catheter or precise diaper weights).

  • Fluid Requirements: Preterm fluid intake target is $160\,\text{mL/kg/day}$.

  • Total Parenteral Nutrition (TPN): A calculated blend of glucose, amino acids, and electrolytes initiated by day $3 - 4$ of life. Long-term use carries risk of liver dysfunction, metabolic complications, and central-line infections.

  • Enteral Feedings: Expressed breastmilk is the gold standard for neonatal nutrition due to its immunologic and digestive benefits. Given via nasogastric (NG) or orogastric (OG) tubes.

  • Gavage Feedings: Administered via continuous drip or intermittent bolus to conserve infant energy.

  • Nonnutritive Sucking: Pacifiers are provided during tube feedings to promote oral-motor development and calm the infant.

• Developmental Care Interventions:

  • Dim lighting to mimic the intra-uterine environment, paired with cyclic lighting schedules to facilitate circadian rhythm development.

  • Quiet environment to minimize alarm fatigue and sensory overload.

  • Slow, gentle handling, clustering nursing interventions, and structured rest periods.

• Discharge Criteria & Safety:

  • Prior to discharge, all high-risk infants must pass a Car Seat Challenge test, remaining in a car seat for $90 - 120\,\text{minutes}$ without experiencing desaturation, bradycardia, or apnea.

Gestational Age and Weight Classifications

• Newborns are categorized by birth weight relative to gestational age:

  • Small-for-Gestational-Age (SGA): Birth weight below the $10^{\text{th}}$ percentile.

  • Appropriate-for-Gestational-Age (AGA): Birth weight between the $10^{\text{th}}$ and $90^{\text{th}}$ percentiles.

  • Large-for-Gestational-Age (LGA): Birth weight above the $90^{\text{th}}$ percentile (exceeding $8.5\,\text{lbs}$ or $3855\,\text{g}$).

Small-for-Gestational-Age (SGA) Newborns & Complications

• SGA infants are frequently affected by Intrauterine Growth Restriction (IUGR).

• Physical Characteristics:

  • Infant appears small and thin with a disproportionately large head relative to the body.

  • Skin is bright pink, smooth, and shiny, with thin epidermis making underlying blood vessels visible.

  • Sparse, fine, fuzzy lanugo hair on scalp.

  • Ear cartilage is soft and pliable; soles and palms show minimal creasing, appearing smooth.

  • Skull bones and ribs feel soft; eyes may remain closed.

• Complication: Cold Stress:

  • SGA infants possess reduced subcutaneous fat and brown adipose tissue reserves.

  • Defined as a core body temperature falling below $96.8^\circ\text{F}$ ($36.0^\circ\text{C}$).

  • Clinical Manifestations: Pale, cold, bluish or mottled skin, lethargy, respiratory distress, and metabolic acidosis.

  • Nursing Care: Place neonate under a radiant warmer; apply warm packs (never directly against skin); maintain head cover with a knit hat; ensure continuous temperature monitoring and adhere to strict feeding schedules.

• Complication: Hypoglycemia:

  • Caused by depleted glycogen stores and impaired gluconeogenesis.

  • Normal blood glucose range is $40 - 60\,\text{mg/dL}$.

  • Clinical Manifestations: Jitteriness, tremors, lethargy, hypotonia, hunger cues, temperature instability, respiratory distress, and seizures.

  • Diagnostic Testing: Obtain blood via heel lance stick.

Large-for-Gestational-Age (LGA) Newborns & Birth Injuries

• Defined as birth weight above the $90^{\text{th}}$ percentile ($> 8.5\,\text{lbs}$).

• Most common underlying maternal etiology is gestational diabetes mellitus.

• Infants present with proportional body enlargement.

• Key complications include Transient Tachypnea of the Newborn (TTN), hypoglycemia, and mechanical birth trauma.

• Transient Tachypnea of the Newborn (TTN):

  • Pathophysiology: Delayed clearance and absorption of fetal lung fluid in alveoli.

  • Risk Factors: LGA infants, infants of diabetic mothers, late preterm births, and delivery via elective Cesarean section without labor.

  • Clinical Manifestations: Progressive respiratory distress, tachypnea (respiratory rate $> 60\,\text{breaths/min}$), expiratory grunting, nasal flaring, intercostal retractions, and cyanosis.

  • Diagnostics: Arterial Blood Gases (ABGs) demonstrate respiratory acidosis. Chest X-ray reveals bilateral interstitial streakiness caused by alveolar fluid retention, presenting in a "sunburst" pattern.

  • Management: Supportive care lasting $2 - 3\,\text{days}$; CPAP for elevated oxygen requirements; infant must remain NPO with IV fluid support while tachypneic to prevent aspiration.

• Skeletal Injury: Clavicle Fracture:

  • Most common birth injury, frequently associated with shoulder dystocia and macrosomia.

  • Clinical Manifestations: Limited or absent movement of the affected arm, crepitus felt over the clavicle, local swelling, and an asymmetrical Moro reflex.

  • Diagnostics: Diagnostic plain X-ray.

  • Management: Gentle handling; position infant off the affected side; immobilize arm with a sling or bandage pinned to clothing. Fractures typically heal completely without surgical intervention within a few weeks.

• Nervous System Injury: Brachial Plexus Injury:

  • Occurs when nerve roots $C5 - T11$ forming the brachial plexus are stretched, compressed, or avulsed during labor (associated with shoulder dystocia, vertex or breech delivery trauma, and macrosomia).

  • Signs: Limp arm hanging flaccid, partial or complete arm paralysis, restricted movement of shoulder, elbow, wrist, or hand, and complete absence of Moro reflex on the affected side.

  • Duchenne-Erb’s Paralysis (Upper Trunk Injury): Involves damage to $C5 - C7$ nerve roots.

  • Klumpke’s Paralysis (Lower Trunk Injury): Involves damage to $C8 - T1$ nerve roots (rarer form).

  • Diagnostics: Neurological evaluation, X-rays, ultrasound, CT, MRI, and electromyography (EMG).

  • Treatment: Passive physical therapy exercises to restore function and prevent flexion contractures. Stretched nerve injuries typically resolve in $3 - 6\,\text{months}$. Avulsed or completely torn nerve roots cannot be restored surgically, resulting in permanent muscular deficits.

• Neurologic Injuries & Hypoxic-Ischemic Brain Injury:

  • Low-birth-weight preterm neonates are at highest risk due to structural fragility of cerebral capillary beds.

  • Ischemia resulting from reduced cerebral blood flow leads to intraventricular hemorrhage (IVH) and intracranial hemorrhage (ICH).

  • Birth asphyxia in term neonates causes hypoxic-ischemic encephalopathy (HIE); therapeutic systemic hypothermia initiated within the first hours reduces cerebral damage.

• Acute Intracranial Hemorrhage (ICH):

  • Bleeding localized into the epidural, subdural, or subarachnoid cranial spaces; most bleeds manifest within the first $72\,\text{hours}$ of life.

  • Severe bleeds cause long-term complications including seizures, intellectual deficits, and cerebral palsy.

  • Clinical Manifestations: Generalized seizures, bulging anterior fontanel, apnea, and sudden altered level of consciousness.

  • Diagnostics: Cranial ultrasound, CT scan, or MRI.

  • Nursing Care: Administration of antiseizure medications (phenobarbital, diazepam); surgical placement of a Ventriculoperitoneal (VP) shunt if obstructive hydrocephalus develops. Primary surgical evacuation of hematomas is rare.

Neonatal Infections & Sepsis

• Neonatal infections are classified by timing and source:

  • Early-Onset / Congenital Sepsis: Pathogens acquired in utero or during transvaginal delivery; manifests within the first $3 - 7\,\text{days}$ of life.

  • Late-Onset Sepsis: Pathogens acquired postnatally from the healthcare environment (Healthcare-Associated Infections - HAIs) or community; manifests after $7 - 30\,\text{days}$.

• Group B Streptococcus (GBS):

  • Major bacterial cause of neonatal pneumonia, meningitis, and overwhelming sepsis.

  • Maternal screening recommended universally at $36 - 37\,\text{weeks}$ gestation via rectovaginal culture to guide intrapartum antibiotic prophylaxis.

• Diagnostic Workup for Sepsis:

  • Blood cultures, urine culture, lumbar puncture (Cerebrospinal fluid - CSF analysis for meningitis).

  • Complete Blood Count (CBC) with differential, evaluating immature-to-total (I/T) neutrophil ratio, platelet count, C-Reactive Protein (CRP), procalcitonin, and serum lactic acid.

• Management:

  • Prompt IV antibiotic or antiviral therapy based on pathogen sensitivities.

  • Continuous monitoring for septic shock and temperature instability.

  • Strict hand hygiene, standard precautions, and skin integrity maintenance.

• TORCH Congenital Infections Complex:

  • T - Toxoplasma gondii: Transmitted via raw meat or cat feces.

  • O - Other Agents: Syphilis, Parvovirus B19, Varicella Zoster Virus, Listeria monocytogenes, Hepatitis B, HIV.

  • R - Rubella: Causes congenital rubella syndrome.

  • C - Cytomegalovirus (CMV): Most common congenital viral infection.

  • H - Herpes Simplex Virus 2 (HSV-2): Transmitted during passage through infected birth canal.

Maternal Substance Exposure & Neonatal Abstinence Syndrome (NAS)

• Maternal Substance Effects:

  • Tobacco: Causes intrauterine growth restriction resulting in SGA infants.

  • Alcohol: Results in Fetal Alcohol Spectrum Disorder (FASD).

  • Opioids: High risk of withdrawal; onset usually $24 - 72\,\text{hours}$, but may be delayed up to $7 - 10\,\text{days}$.

  • Cocaine & Methamphetamines: Immediate toxicity; causes maternal vasoconstriction leading to placental abruption, premature rupture of membranes (PROM), preterm delivery, and fetal death.

• Neonatal Abstinence Syndrome (NAS) / Neonatal Opioid Withdrawal Syndrome (NOWS):

  • Clinical constellation of withdrawal symptoms in infants exposed to addictive substances in utero.

  • Diagnostic confirmation via neonatal urine and meconium drug screening assays.

  • Clinical Manifestations:

  • Central Nervous System: High-pitched inconsolable cry, excessive irritability, tremors, exaggerated/hyperactive Moro reflex, hypertonia, seizures, disrupted sleep patterns.

  • Gastrointestinal: Poor feeding, excessive uncoordinated sucking, loose stools, diarrhea, vomiting, regurgitation.

  • Metabolic / Vasomotor / Respiratory: Fever ($\ge 37.2^\circ\text{F}$ / $99^\circ\text{F}$), diaphoresis, sweating, nasal stuffiness, sneezing ($\ge 4$ per scoring interval), frequent yawning ($\ge 4$ per interval), tachypnea ($> 60\,\text{breaths/min}$), skin excoriation from constant rubbing.

• Assessment & Scoring Tools:

  • Finnegan Neonatal Abstinence Scoring System (FNASS): Quantitative assessment evaluating 21 clinical signs every $3 - 4\,\text{hours}$.

  • Eat, Sleep, Console (ESC) Care Tool: Function-based assessment focusing on whether the infant can eat adequately, sleep for at least $1\,\text{hour}$, and be consoled within $10\,\text{minutes}$.

• Non-Pharmacological Care Interventions:

  • Swaddling, rooming-in with parent, low-light and quiet environment, minimal handling, skin-to-skin contact, non-nutritive sucking with pacifiers, holding by dedicated cuddlers, and clustering nursing care.

• Pharmacological Management:

  • Initiated when non-pharmacological methods fail to control withdrawal symptoms.

  • First-line oral medications: Morphine oral solution, Phenobarbital, Clonidine.

Hemolytic Disorders & Infants of Diabetic Mothers

• Rh Incompatibility (Isoimmunization):

  • Occurs when an Rh-negative mother carries an Rh-positive fetus.

  • Fetal red blood cells enter maternal circulation, stimulating production of anti-Rh antibodies.

  • Maternal antibodies cross the placenta in subsequent pregnancies, destroying fetal red blood cells.

  • Causes Erythroblastosis Fetalis, leading to severe fetal anemia, heart failure, and generalized hydrops (Hydrops Fetalis).

  • Prevention: Administration of Rho(D) Immune Globulin (RhIG / RhoGAM) to Rh-negative mothers at $28\,\text{weeks}$ gestation and within $72\,\text{hours}$ post-delivery.

• ABO Incompatibility:

  • Occurs most commonly when mother has Type O blood and fetus has Type A or B blood.

  • Maternal anti-A or anti-B antibodies cross placenta, causing mild to moderate neonatal hemolysis.

  • Manifests as early-onset jaundice within $24\,\text{hours}$ of birth and a positive Direct Coombs test.

  • Treatment: Phototherapy; severe cases require exchange blood transfusion or intrauterine transfusion.

• Infants of Diabetic Mothers (IDM):

  • Maternal hyperglycemia leads to fetal hyperinsulinemia, acting as a growth hormone.

  • Clinical Features: LGA appearance, excessive fat deposition, large size.

  • Complications: High risk of shoulder dystocia, clavicle fractures, birth asphyxia, and congenital cardiac malformations.

  • Postnatal Risk: Rapid development of severe hypoglycemia following umbilical cord clamping due to persistent hyperinsulinemia.

  • Management: Maintain thermal stability; initiate early enteral carbohydrate feedings (oral preferred). If serum glucose remains low, infuse $10\%$ Dextrose in Water ($\text{D10W}$) intravenously.

Congenital Anomalies & Surgical Management

• Congenital anomalies represent the leading cause of infant mortality under $1\,\text{year}$ of age (cardiac defects being most common).

• Congenital Hydrocephalus:

  • Excessive fluid accumulation of Cerebrospinal Fluid (CSF) within the cerebral ventricles, leading to progressive ventricular dilation and increased intracranial pressure.

  • Diagnosed at birth or in utero; increases risk for intracranial hemorrhage.

  • Treatment: Surgical placement of a Ventriculoperitoneal (VP) Shunt, which channels excess CSF from brain ventricles down into the peritoneal cavity for reabsorption.

• Cleft Lip and Cleft Palate:

  • Fourth most common congenital defect; multifactorial origin.

  • Cleft Lip: Unilateral or bilateral visible fissure of the upper lip. Causes feeding difficulties. Surgical repair performed at approximately $3\,\text{months}$ of age.

  • Cleft Palate: Fissure extending through the hard or soft palate, creating direct communication between oral and nasal cavities. Causes sucking failure and speech defects. Surgical repair performed before $6\,\text{months}$ of age (completed by $18\,\text{months}$) to prevent long-term speech delays.

• Congenital Diaphragmatic Hernia (CDH):

  • Herniation of abdominal contents (stomach, intestines, liver) through an unclosed diaphragmatic defect into the thoracic cavity.

  • Prevents normal fetal lung development, causing severe pulmonary hypoplasia.

  • Clinical Manifestations: Scaphoid abdomen paired with a barrel-shaped chest, severe respiratory distress, tachypnea, cyanosis, and absent/diminished breath sounds on the affected side.

  • Diagnostics: Diagnostic Chest X-ray.

  • Management: SURGICAL EMERGENCY. Immediate endotracheal intubation. NEVER use bag-valve-mask ventilation (mask ventilation forces air into herniated bowel within the chest, compressing lungs and risking bowel rupture). Insert NG tube for continuous gastric decompression. Emergency surgical repair required.

• Gastroschisis:

  • Full-thickness anterior abdominal wall defect, typically located to the right of the umbilicus, with eviscerated stomach and bowel herniating without a protective membrane or sac.

  • Management: Keep eviscerated bowel sterile by wrapping in warm, saline-moistened dressings covered with plastic; place neonate's lower body in a sterile transparent silo for gradual gravity-assisted reduction; maintain supine positioning; insert NG/OG decompression tube; infuse IV fluids at $1.5\times$ maintenance volume to compensate for massive evaporative fluid loss; administer IV prophylactic antibiotics; use latex-free equipment; surgical closure performed within $24\,\text{hours}$.

• Omphalocele:

  • Central abdominal wall defect at the base of the umbilical cord ring where abdominal organs protrude enclosed within a thin protective peritoneal sac.

  • High association with coexisting genetic and chromosomal syndromes.

  • Management: Protect sac with warm, sterile, saline-moistened gauze; maintain supine positioning; insert NG tube; preserve hydration and body heat. Small omphaloceles undergo single operative repair; giant omphaloceles require staged compression closure.

Prematurity & Respiratory Complications

• Preterm birth is defined as delivery occurring before $37\,\text{weeks}$ completed gestation.

• Characterized by overall organ system immaturity, small/scrawny appearance, disproportionately large head, translucent skin, and abundant lanugo.

• Respiratory Distress Syndrome (RDS):

  • Etiology: Deficient pulmonary surfactant production by immature type II alveolar cells.

  • Clinical Manifestations: Tachypnea, dyspnea, nasal flaring, intercostal and xiphoid retractions, expiratory grunting, cyanosis, pallor, fine crackles, and apnea.

  • Evaluation: Evaluated using the Silverman-Anderson Respiratory Distress Score (evaluating upper chest movement, lower chest retractions, xiphoid retractions, nares dilation, and expiratory grunt on a scale of 0 to 2).

  • Diagnostics: ABGs show severe hypoxemia and hypercapnia. Chest X-ray reveals diffuse ground-glass reticulogranular opacities ("light lung appearance").

  • Treatment: Endotracheal administration of exogenous surfactant; warmed, humidified oxygen via hood, CPAP, or mechanical ventilation; ECMO for refractory cases.

• Apnea of Prematurity:

  • Spontaneous cessation of breathing lasting greater than $20\,\text{seconds}$, or shorter pauses accompanied by abrupt pallor, hypotonia, cyanosis, bradycardia, and oxygen desaturation.

  • Pharmacological Treatment: Theophylline acts as a respiratory stimulant; Caffeine citrate is the primary drug of choice for long-term management.

• Bronchopulmonary Dysplasia (BPD):

  • Chronic pulmonary lung disease resulting from prolonged mechanical ventilation, high peak inspiratory pressures, toxic oxygen levels, and structural alveolar immaturity.

  • Clinical Manifestations: Chronic dyspnea, barrel chest, wheezing, tachypnea, and inability to wean from oxygen therapy ("little COPD infants").

  • Management: Utilize lowest effective oxygen concentration; administer bronchodilators (albuterol, theophylline), steroids (to reduce airway inflammation), and diuretics (furosemide to clear pulmonary edema). Must pass Car Seat Challenge before discharge.

• Necrotizing Enterocolitis (NEC):

  • MEDICAL AND SURGICAL EMERGENCY. Acute ischemic necrosis of the intestinal mucosa, heavily associated with prematurity and enteral feeding introduction.

  • Clinical Manifestations: Abdominal distension, shiny/discolored abdominal wall, gastric retention/residuals, bilious (green) vomiting, bloody stools, lethargy, poor feeding, hypotension, apnea, oliguria, and thermal instability.

  • Diagnostics: Abdominal X-ray showing sausage-shaped intestinal dilation and pneumatosis intestinalis (gas in bowel wall). Labs reveal leukocytosis, anemia, electrolyte disturbances, and metabolic acidosis.

  • Nursing Care: Immediate NPO status for $3 - 14\,\text{days}$; continuous gastric decompression via NG suction; IV fluid resuscitation; TPN administration; broad-spectrum IV antibiotics; urgent surgical consult for bowel resection or temporary ostomy.

• Retinopathy of Prematurity (ROP):

  • Abnormal retinal vasoproliferation in response to retinal vessel immaturity and hyperoxia/hypoxia swings.

  • Risk Factors: Gestational age $< 32\,\text{weeks}$, birth weight $< 1500\,\text{g}$, RDS, prolonged high oxygen exposure, bright light exposure, sepsis, and meningitis.

  • Management: Maintain target oxygen saturations above $93\%$; reduce ambient room lighting; apply incubator covers; serial retinal exams by an ophthalmologist.

Post-Term Infants & Meconium Aspiration Syndrome (MAS)

• Delivered at or after $42\,\text{weeks}$ gestation.

• Clinical Features: Absence of lanugo, minimal/absent vernix caseosa, abundant scalp hair, long fingernails, dry/cracked/parchment-like skin, meconium skin staining, barrel chest, and respiratory distress.

• Meconium Aspiration Syndrome (MAS):

  • Pathophysiology: Fetal intrauterine hypoxia causes anal sphincter relaxation and deep gasping, leading to aspiration of meconium-stained amniotic fluid into airways. Meconium causes chemical pneumonitis, mechanical airway obstruction, and inactivates endogenous surfactant.

  • Clinical Manifestations: Meconium staining of skin, nails, and umbilical cord; acute respiratory distress at birth; barrel chest from air trapping; coarse rales and rhonchi on auscultation.

  • Diagnostics: Chest X-ray reveals bilateral patchy irregular opacities, atelectasis, and hyperinflation.

  • Complications: Pneumothorax (requires emergency chest tube drainage).

  • Treatment: Respiratory and circulatory support, oxygen via hood/CPAP, mechanical ventilation, exogenous surfactant, inhaled nitric oxide, and Extracorporeal Membrane Oxygenation (ECMO).

Metabolic Conditions & Inborn Errors of Metabolism

• Universal Newborn Screening is performed via heel stick blood collection (Guthrie card) after $24\,\text{hours}$ of age to screen for over 65 inborn errors of metabolism.

• Phenylketonuria (PKU):

  • Autosomal recessive amino acid disorder caused by deficiency of phenylalanine hydroxylase, blocking conversion of phenylalanine to tyrosine.

  • Toxic levels accumulate in blood and brain. Asymptomatic at birth; untreated cases lead to severe intellectual disability, microcephaly, seizures, behavioral disturbances, skin rashes, and a characteristic musty body odor.

  • Diagnostics: Guthrie Blood Test performed at a minimum of $24\,\text{hours}$ after starting milk feeds; retest in $7 - 10\,\text{days}$ to catch false negatives.

  • Management: Strict lifelong low-phenylalanine diet. Eliminate high-protein foods (meat, dairy products, dry beans, nuts, eggs). Consume specialized phenylalanine-free formula. Cereals, fruits, and vegetables permitted in strict moderation.

• Galactosemia:

  • Autosomal recessive disorder preventing enzyme conversion of galactose into glucose.

  • Accumulation of unmetabolized milk sugars causes brain damage, nuclear cataracts, jaundice, hepatomegaly/liver failure, and kidney injury.

  • Clinical Manifestations: Vomiting, failure to thrive, poor feeding, jaundice, hepatomegaly.

  • Treatment: Absolute, lifelong elimination of galactose and lactose from diet (use lactose-free, soy-based formulas).

• Congenital Hypothyroidism:

  • Results from thyroid gland dysgenesis, inborn errors of thyroid synthesis, or iodine deficiency. High incidence in preterm infants (demonstrating elevated TSH and low $T_4$ levels).

  • Clinical Manifestations: Prolonged neonatal jaundice, hoarse cry, generalized hypotonia, macroglossia (large protruding tongue), somnolence, and feeding difficulty.

  • Treatment: Lifelong thyroid hormone replacement with levothyroxine.

• Maple Syrup Urine Disease (MSUD):

  • Autosomal recessive defect in branched-chain amino acid metabolism, causing toxic buildup of ketoacids. High incidence in Mennonite populations.

  • Clinical Manifestations: Urine and sweat smell distinctly of sweet maple syrup; poor feeding, vomiting, hyperreflexia, opisthotonos, and seizures. Often fatal if untreated.

  • Treatment: Protein-restricted diet low in branched-chain amino acids, thiamine supplements, and special formula.

Care of the Family Experiencing Neonatal Loss

• Nurse’s Role:

  • Prepare parents for inevitable death, deliver end-of-life palliative care, and facilitate the family's grieving process.

  • Provide private opportunities for parents to see, touch, hold, caress, and talk to their infant before and during death.

• Tangible Memory Artifacts:

  • Create memory boxes containing lock of hair, footprints, handprints, identification bands, tape measure, clothing, blankets, and photographs.

• National Observance: Infant & Pregnancy Loss Remembrance Day is observed annually on October 15.

NCLEX & Clinical Case Review

• NCLEX Question 1:

  • Question: The nurse is caring for an SGA infant. Which complication is the highest priority concern?

  • Options: A. Bronchopulmonary dysplasia | B. Clavicle fracture | C. Hypothermia | D. Low stimulus environment

  • Answer: C. Hypothermia (SGA infants lack subcutaneous fat and brown fat reserves, placing them at severe risk for cold stress).
