Section Title
Prematurity & Low Birth Weight (LBW) Classification
Important Facts
- Preterm infants lack surfactant (matures around 34–35 weeks) → respiratory distress risk
- Minimal brown fat and subcutaneous tissue → rapid heat loss and cold stress
- Weak suck-swallow-gag reflex before ~34 weeks → gavage feeding required
- Fragile germinal-matrix vessels → intraventricular hemorrhage (IVH) risk
- Immature immune system → high infection/sepsis risk
- Immature retinal vessels + high oxygen = retinopathy of prematurity (ROP)
- Immature liver → hyperbilirubinemia and hypoglycemia
- Feeds: breast milk preferred; small, frequent volumes (10–20 mL/kg/day initially); advance slowly
Key Definitions
Term
Preterm (Premature) Infant
Example
Infant born at 35 weeks gestation = preterm, even if weight is 2,800 g
Definition
Born before 37 completed weeks of gestation, regardless of weight.
Term
Low Birth Weight (LBW)
Example
Term infant (40 weeks) weighing 2,200 g = LBW
Definition
Newborn weighing under 2,500 g at birth, independent of gestational age.
Term
Very Low Birth Weight (VLBW)
Example
Preterm infant at 28 weeks, 1,200 g = VLBW
Definition
Birth weight under 1,500 g.
Term
Extremely Low Birth Weight (ELBW)
Example
Periviable infant at 22–23 weeks, 600 g = ELBW
Definition
Birth weight under 1,000 g; highest morbidity/mortality risk.

Section Title
Respiratory Distress Syndrome (RDS)
Important Facts
- RDS occurs chiefly in preterm infants <34 weeks; maternal diabetes and cesarean without labor increase risk
- Manifestations BEGIN WITHIN HOURS of birth: tachypnea (>60/min), grunting, nasal flaring, intercostal/subcostal/sternal retractions, cyanosis, see-saw (paradoxical) breathing
- CXR findings: diffuse reticulogranular (ground-glass) pattern with air bronchograms
- EXOGENOUS SURFACTANT is THE mainstay treatment — beractant, poractant alfa, or calfactant instilled into ETT
- Surfactant rapidly improves lung compliance within minutes to hours
- Oxygen titrated to target SpO2 (typically 90–95% in preterm); hyperoxia → retinopathy of prematurity
- ANTENATAL prevention: maternal betamethasone (12 mg IM × 2, 24 hr apart) or dexamethasone accelerates fetal lung maturity if preterm birth likely between 24–34 weeks
- Supportive care: thermoregulation, IV fluids, minimal handling, continuous monitoring
Key Definitions
Term
Respiratory Distress Syndrome (RDS)
Example
28-week preterm infant with ground-glass CXR pattern, grunting, retractions within 2 hours of birth
Definition
Acute lung disease in preterm infants caused by surfactant deficiency; alveoli collapse (atelectasis), compliance ↓, work of breathing ↑.
Term
Surfactant
Example
Beractant (Survanta) is an exogenous surfactant given via endotracheal tube
Definition
Phospholipid mixture that reduces surface tension in alveoli, allowing them to remain open at end-expiration.
Term
Grunting
Example
Audible 'guh-guh-guh' sound with each breath in RDS
Definition
Partial closure of the glottis during expiration to maintain positive end-expiratory pressure and keep alveoli open; a sign of respiratory distress.

TTN resolution timeline
Section Title
Related Transitional Respiratory Disorders
Important Facts
- TTN: common after elective cesarean (no labor to squeeze out fetal lung fluid)
- TTN: CXR shows fluid in the fissures and hyperinflation; supportive care only
- MAS: risk factors are post-term gestation (>42 weeks), oligohydramnios, cord compression, and fetal distress
- MAS: meconium is a chemical irritant and can cause surfactant inactivation
- MAS: mechanical ventilation often needed; risk of air leak (pneumothorax, pneumomediastinum)
- MAS: surfactant may be beneficial; inhaled nitric oxide (iNO) for severe hypoxemia
Key Definitions
Term
Transient Tachypnea of the Newborn (TTN)
Example
Term infant after cesarean delivery with RR 80, mild retractions → TTN, improves by day 2
Definition
Retained fetal lung fluid causing mild respiratory distress; resolves within 24–72 hours without specific treatment.
Term
Meconium Aspiration Syndrome (MAS)
Example
Thick meconium-stained amniotic fluid + fetal distress → MAS with air trapping and pneumothorax risk
Definition
Meconium in the airways causing mechanical obstruction and chemical pneumonitis; seen in post-term and stressed infants.

- TTN vs RDS vs MAS differentiation (CXR, timeline, treatment)
Formulas
Formula
Visible jaundice threshold ≈ Total serum bilirubin (TSB) of 5 mg/dL
Meaning
TSB = total serum bilirubin concentration; visible yellowing of skin/sclera appears at ~5 mg/dL
Watch Out
Phototherapy threshold is NOT 5 mg/dL — it depends on age (hours of life) and risk category. Use the Bhutani nomogram.
When To Use
Any newborn with visible jaundice → measure TSB immediately; do not guess
Formula
Kernicterus risk threshold (term infant) ≈ TSB >20–25 mg/dL
Meaning
Unconjugated bilirubin >20–25 mg/dL in a term infant approaches the danger zone for bilirubin encephalopathy; much lower thresholds in preterm/ill infants
Watch Out
Preterm, LBW, hemolytic disease, acidosis, sepsis, hypoglycemia = LOWER thresholds. A 30-week infant at 15 mg/dL is already at very high risk.
When To Use
Assessing risk of bilirubin neurotoxicity and need for exchange transfusion
Formula
Conjugated (direct) bilirubin >2 mg/dL OR >20% of total = PATHOLOGIC
Meaning
Conjugated bilirubin should be minimal; if >2 mg/dL or >20% of total, suspect hepatic/biliary disease
Watch Out
Conjugated hyperbilirubinemia always requires investigation (biliary atresia, neonatal hepatitis, cholestasis). Never dismiss as 'just jaundice.'
When To Use
Evaluating jaundice that persists beyond 2–3 weeks or rises slowly but steadily

Section Title
Hyperbilirubinemia & Jaundice — CRITICAL for NLE
Important Facts
- JAUNDICE WITHIN THE FIRST 24 HOURS IS PATHOLOGIC UNTIL PROVEN OTHERWISE — immediately investigate for hemolysis, infection, or other disease
- Physiologic jaundice appears AFTER 24 hours; peaks day 3–5; resolves by day 7 in term infants
- The Bhutani HOUR-SPECIFIC NOMOGRAM is the gold standard for determining phototherapy thresholds — TSB value depends on postnatal age in hours and risk category (low, medium, high)
- Phototherapy CONVERTS unconjugated bilirubin in the skin to water-soluble isomers the infant can excrete
- EXCHANGE TRANSFUSION is for severe, rapidly rising, or phototherapy-resistant hyperbilirubinemia (approaching ~20–25 mg/dL in term, lower in preterm/ill)
- Risk factors for severe jaundice: prematurity, hemolytic disease, sepsis, acidosis, hypoglycemia, asphyxia, isoimmunization
- Rh disease: give Rho(D) immune globulin (RhoGAM) to Rh-negative, unsensitized mothers within 72 hours of Rh-positive birth to prevent future sensitization
- Phototherapy nursing: COVER THE EYES with opaque patches (prevent retinal damage), UNDRESS for maximum skin exposure, KEEP THE GENITALS COVERED for modesty/warmth, maintain hydration/feeding (loose green stools expected), reposition every 2 hours, monitor temperature (overheating/cooling both harmful), keep serum bilirubin measurements in subdued light to avoid false ↓ readings
Key Definitions
Term
Physiologic Jaundice
Example
Healthy term infant, breast-feeding well, jaundice visible on day 3, TSB 12 mg/dL
Definition
Jaundice appearing AFTER the first 24 hours (typically day 2–3), peaking around day 3–5, resolving within ~7 days in term infants; benign, requires monitoring but no urgent treatment.
Term
Pathologic Jaundice
Example
Jaundice visible at 6 hours of life in Rh-negative mother/Rh-positive infant → suspect hemolytic disease
Definition
Jaundice appearing WITHIN the first 24 hours, rising rapidly, persisting, or associated with hemolysis/sepsis/disease; requires investigation and treatment.
Term
Breastfeeding (Early) Jaundice
Example
Infant fed every 4–5 hours, TSB rising, improves with 8–12 feeds per day
Definition
Jaundice in first week due to insufficient milk intake (inadequate feeding frequency or transfer); resolves with improved breastfeeding.
Term
Breast-Milk (Late) Jaundice
Example
Well-feeding infant with TSB 16 mg/dL at day 10 of life; resolves with continued breast-feeding
Definition
Jaundice appearing after the first week, related to a component of breast milk that increases bilirubin reabsorption; generally benign but may require phototherapy.
Term
Hemolytic Disease (Rh/ABO Incompatibility)
Example
Rh-negative unsensitized mother with Rh-positive infant → jaundice at 6–12 hours, TSB rising 0.2 mg/dL/hour
Definition
Maternal antibodies (IgG) cross the placenta and destroy fetal RBCs → rapid jaundice, anemia, hydrops in severe cases.
Term
Kernicterus (Bilirubin Encephalopathy)
Example
Untreated severe jaundice in preterm infant → seizures at day 4, permanent choreoathetoid cerebral palsy
Definition
Permanent neurologic damage from unconjugated bilirubin deposition in the basal ganglia; manifests as lethargy, poor feeding, high-pitched cry, hypertonia, opisthotonus, and lasting motor/cognitive deficits.
Term
Unconjugated (Indirect) Bilirubin
Example
TSB 18 mg/dL in a term infant is almost entirely unconjugated (direct <0.5 mg/dL)
Definition
Fat-soluble form produced from RBC hemoglobin breakdown; can cross the blood-brain barrier and cause kernicterus.
Term
Conjugated (Direct) Bilirubin
Example
Infant with cholestasis: total bilirubin 8 mg/dL, direct 4 mg/dL (conjugated hyperbilirubinemia)
Definition
Water-soluble form produced by hepatic conjugation; excreted into bile; does NOT cross blood-brain barrier.
Diagrams To Know

Section Title
Phototherapy Management (Nursing Focus)
Important Facts
- Eye protection MANDATORY: cover eyes with opaque patches to prevent retinal photodamage (patches must be secure but not compress the globes)
- Maximum skin exposure: remove all clothing except diaper; place infant under lights (overhead phototherapy unit or fiber-optic blanket underneath)
- Genitals: small covering to preserve modesty and retain heat
- Temperature monitoring: phototherapy lights generate heat → risk of overheating; maintain thermoneutral environment (36.5–37.5°C); also prevent hypothermia from undressing
- Feeding & hydration: maintain or increase frequency (phototherapy + fluid loss = dehydration risk); loose, greenish stools are EXPECTED (increased bile pigment excretion)
- Positioning: rotate infant every 2 hours to ensure all skin surfaces are exposed and irradiated
- Serum bilirubin sampling: perform in subdued light to prevent falsely LOW readings (bilirubin photodegraded by excessive room light); check TSB 4–6 hours after starting phototherapy, then every 4–8 hours depending on trend and risk
- Phototherapy efficacy: depends on irradiance (light intensity), spectrum, surface area exposed, and bilirubin level
- Home phototherapy: fiber-optic blankets may be used for mild hyperbilirubinemia; requires close follow-up and parental education
Key Definitions
Term
Phototherapy
Example
Infant under phototherapy lights with eyes covered and maximum skin exposure; serum bilirubin drops 0.1–0.3 mg/dL/hour with effective treatment
Definition
Use of blue/blue-green light (460–490 nm wavelength) to convert unconjugated bilirubin in the skin to water-soluble isomers (lumirubin, configurational isomers) that can be excreted without hepatic conjugation.

Section Title
Neonatal Sepsis
Important Facts
- Early-onset sepsis: causative organisms are GROUP B STREPTOCOCCUS (GBS/Strep B) and E. COLI (gram-negative); account for ~70% of EOS cases
- EOS risk factors: maternal GBS colonization, prolonged rupture of membranes (PROM >18 hours), maternal fever/chorioamnionitis, low birth weight, prematurity, intrapartum fever
- LOS: common organisms include Staphylococcus epidermidis (central lines), Candida, Serratia, Pseudomonas, other nosocomial pathogens
- SIGNS ARE SUBTLE AND NONSPECIFIC — think 'the baby just isn't doing well': temperature instability (OFTEN HYPOTHERMIA, not fever), poor feeding, lethargy or irritability, tachypnea/apnea/respiratory distress, tachycardia or bradycardia, hypotonia, tremors, seizures, jaundice (especially conjugated), hepatosplenomegaly, poor perfusion (mottling, delayed capillary refill >3 seconds), metabolic acidosis
- Hypoglycemia and hyperglycemia both can occur; watch glucose closely
- MANAGEMENT: obtain cultures (blood, urine, CSF if meningitis suspected) BEFORE starting antibiotics if infant is stable; do NOT delay antibiotics while awaiting cultures
- Empiric therapy for EOS: IV AMPICILLIN (50 mg/kg/dose Q6–12h) PLUS GENTAMICIN (7.5 mg/kg/dose Q18–24h or Q12h depending on age and renal function); continue until culture results and sensitivities available, then de-escalate
- Empiric therapy for LOS: vancomycin + gentamicin ± fluconazole, depending on NICU flora and risk
- Full sepsis workup: CBC (WBC may be elevated, normal, or low; left shift; thrombocytopenia is ominous), blood glucose, blood gas, LFTs, CRP/procalcitonin (elevated in infection)
- PREVENTION: intrapartum antibiotic prophylaxis (IV penicillin G or ampicillin) for GBS-positive mothers reduces EOS risk by ~90%; give during labor, not at delivery
- Hand hygiene is the SINGLE MOST IMPORTANT prevention measure; strict adherence reduces nosocomial infections
Key Definitions
Term
Neonatal Sepsis
Example
28-day-old infant with lethargy, poor feeding, and hypothermia → blood cultures positive for Group B Streptococcus
Definition
Systemic bacterial infection in a newborn during the first 28 days of life; manifests with nonspecific signs and is life-threatening without prompt treatment.
Term
Early-Onset Sepsis (EOS)
Example
GBS-positive mother, infant with tachypnea and temperature instability at 8 hours of life
Definition
Sepsis appearing within the first 72 hours of life; usually acquired from the maternal genital flora during delivery.
Term
Late-Onset Sepsis (LOS)
Example
Preterm infant in NICU for 2 weeks develops fever and feeding intolerance; blood culture grows Staphylococcus epidermidis
Definition
Sepsis appearing after 72 hours of life; often nosocomial or acquired from the environment/caregivers.

Section Title
Common Congenital Anomalies — Nursing Priorities
Important Facts
- CLEFT LIP/PALATE: feeding challenge due to inability to create intraoral negative pressure; use special wide-based, squeezable bottles or spoon-feeding; position upright; burp frequently to prevent aspiration; surgical repair staged (lip at 3 months, palate at 9–12 months); post-op protect the suture line (elbow restraints, no prone, soft diet) for 7–10 days
- CLEFT LIP/PALATE: psychosocial support critical — parents may feel guilt; emphasize normal development with treatment; coordinate with cleft team (surgeon, speech pathology, genetics, prosthodontics)
- EA/TEF: the '3 Cs' — COUGHING, CHOKING, CYANOSIS with the first feed or excessive DROOLING and frothy secretions; keep NPO, suction (gentle, to prevent trauma), elevate head of bed 30–45 degrees, insert a Replogle (double-lumen) tube in the proximal esophagus for continuous suction to prevent aspiration; prepare for immediate surgical repair
- EA/TEF: chest or abdominal X-ray shows the tube coiled in the upper esophagus; abdomen may be distended if TEF present (air enters the stomach via the fistula)
- DIAPHRAGMATIC HERNIA: respiratory distress at birth with scaphoid (concave) abdomen (because bowel is in chest, not belly); DO NOT use bag-mask ventilation (inflates the bowel in the chest, worsening compression) — intubate promptly; place an orogastric (not nasogastric) tube for continuous low suction to decompress the stomach; position with head elevated and TOWARD THE AFFECTED SIDE (allows lungs on unaffected side to expand); oxygen, IV access, avoid aggressive hand-bagging; prepare for surgical repair within hours to days
- MYELOMENINGOCELE: COVER WITH STERILE, SALINE-MOISTENED DRESSING (NOT DRY) to prevent drying and bacterial invasion; keep PRONE or in a side-lying position (avoid pressure on the sac); prevent contamination with stool/urine; measure head circumference every 4–6 hours to detect hydrocephalus (rapid growth, bulging fontanel, increasing OFC); monitor for signs of infection (fever, lethargy, feeding difficulty); neurosurgical consultation for sac repair (usually within 24–48 hours); assess lower limb motor/sensory function and bowel/bladder involvement
- IMPERFORATE ANUS: failure of anal opening to form; recognized by absence of meconium stool by 24 hours and visible absence of anal opening; may have fistulous connection to the urethra or perineum; probe cautiously; abdominal/pelvic imaging (ultrasound/MRI) to determine the level of the malformation; surgical repair (may be staged); post-repair, careful perineal care and assessment of continence
- GASTROSCHISIS: abdominal wall defect with exposed bowel loops covered only by peritoneum/fascia (NOT a true hernia sac); high risk of infection, evaporative heat loss, and hypothermia; cover with sterile saline-moistened gauze and plastic wrap; keep NPO; IV fluids; NG tube; gradual closure (primary or staged with silo); high mortality if infected or delayed
- OMPHALOCELE: abdominal wall defect with true hernia sac containing abdominal contents; covered by peritoneum; similar care to gastroschisis but lower infection risk initially; surgical closure
- CONGENITAL HEART DEFECTS (PDA, ASD, VSD, TGA, TOF): recognize signs (cyanosis, murmur, poor feeding, failure to thrive); prostaglandin E1 (PGE1) keeps the ductus arteriosus open in duct-dependent lesions; oxygen therapy may worsen some lesions (e.g., TGA with intact septum — allows mixing; if SpO2 low, increase inspired oxygen and avoid hyperventilation); coordinate with pediatric cardiology
- DOWN SYNDROME (Trisomy 21): recognize phenotype (upslanting palpebral fissures, low-set ears, single palmar crease, hypotonia); obtain karyotype or FISH for confirmation; screen for congenital heart defect (AV canal defect common), GI anomalies (duodenal atresia), and atlantoaxial instability; provide supportive care, feeding assistance (hypotonia), and family education
Key Definitions
Term
Cleft Lip/Palate
Example
Bilateral cleft lip and palate; infant has difficulty creating intraoral pressure for sucking
Definition
Failure of fusion of the lip and/or palate during embryonic development; affects feeding, speech, and psychosocial development.
Term
Esophageal Atresia / Tracheoesophageal Fistula (EA/TEF)
Example
Excessive drooling, coughing with feeding attempts, respiratory distress (the '3 Cs')
Definition
Abnormal connection between the esophagus and trachea; the upper esophagus is a blind pouch; gastric contents can reflux into the lungs.
Term
Diaphragmatic Hernia
Example
Bowel loops in the chest cavity on CXR; scaphoid abdomen; respiratory distress at birth
Definition
Defect in the diaphragm allowing abdominal contents (bowel, liver) to herniate into the thoracic cavity, compressing the lungs.
Term
Myelomeningocele (Open Spina Bifida)
Example
Exposed neural sac on the lower back; risk of infection and ascending neurologic deterioration; hydrocephalus common
Definition
Incomplete closure of the vertebral column and meninges; neural tissue protrudes through the defect as a fluid-filled sac.

Section Title
Infant of a Diabetic Mother (IDM)
Important Facts
- IDM: MACROSOMIA → birth injury risk: shoulder dystocia, brachial plexus injury, clavicular fracture, Erb's palsy; careful delivery; monitor upper extremity movement post-delivery
- IDM: HYPOGLYCEMIA is the major metabolic complication — insulin persists even after glucose supply is cut; blood glucose can plummet to <30 mg/dL within the first 1–2 hours of life
- IDM: screen for hypoglycemia frequently (at 1 hour, 2 hours, 4 hours, then Q4h for 24–48 hours); target glucose >45 mg/dL (some sources cite >40 mg/dL); if <45 mg/dL, feed immediately or give IV dextrose (10% dextrose, ~0.5–1 g/kg)
- IDM: EARLY FEEDING is the mainstay of prevention — breast milk or formula every 1–2 hours in first 24 hours; combined with glucose monitoring
- IDM: hypocalcemia (rare but possible) — monitor ionized calcium if infant shows jitteriness, tremors, or seizures (within first 24–72 hours)
- IDM: polycythemia (elevated hematocrit) — caused by chronic intrauterine hypoxia stimulating erythropoiesis; manifests as plethora, poor perfusion, and increased risk of thrombosis; monitor Hct; may need partial exchange transfusion if Hct >70% with symptoms
- IDM: hyperbilirubinemia — from polycythemia and immature liver; more common and severe; monitor TSB closely
- IDM: respiratory distress — insulin delays surfactant maturation; RDS or transient tachypnea more common; prepare for respiratory support
- IDM: congenital anomalies — maternal diabetes in 1st trimester (especially Type 1) increases risk of cardiac (transposition, VSD), spinal, and renal anomalies; careful examination and imaging
Key Definitions
Term
Infant of a Diabetic Mother (IDM)
Example
Mother with Type 1 diabetes, infant birth weight 4,500 g (macrosomic), blood glucose 35 mg/dL at 2 hours of life (hypoglycemia)
Definition
Newborn of a mother with pre-gestational or gestational diabetes; fetal hyperinsulinemia leads to macrosomia, hypoglycemia, and other complications.
Term
Macrosomia
Example
Large infant with abdominal/shoulder girth disproportionate to head circumference; shoulder dystocia risk
Definition
Birth weight >4,000 g (or >90th percentile for gestational age); results from increased glycogen and fat deposition in response to chronic intrauterine hyperglycemia.
Term
Fetal Hyperinsulinemia
Example
Maternal glucose spikes → fetal hyperglycemia → fetal pancreas secretes insulin → fetal growth; cord clamping → glucose supply stops, but fetal insulin persists → neonatal hypoglycemia
Definition
Elevated fetal insulin levels in response to maternal hyperglycemia; drives anabolic growth and, after birth (when maternal glucose is removed), causes severe hypoglycemia.

Section Title
Thermoregulation & Cold Stress
Important Facts
- Preterm infants have MINIMAL BROWN FAT and thin subcutaneous tissue → rapid heat loss and inability to rewarm
- Heat loss mechanisms: RADIATION (to cool environment), EVAPORATION (wet skin), CONDUCTION (direct contact with cold surfaces), CONVECTION (cold air flow)
- Prevent heat loss: dry infant immediately after delivery, place under radiant warmer, avoid drafts, use incubator with humidity for preterm <32 weeks, provide hat and booties, perform skin-to-skin (kangaroo) care, minimize exposure during procedures
- KANGAROO CARE (skin-to-skin contact): mother's breast becomes a biological incubator; infant maintains temperature, stabilizes heart rate/RR, improves oxygen saturation, enhances bonding, and improves breastfeeding success; strongly recommended by WHO and Philippine DOH for preterm and LBW infants
- Monitor temperature: axillary preferred in infants (core approximated); avoid rectal (perforation risk in preterm); some units use skin temperature probes
- Overheating is also dangerous: avoid excessive blankets/radiant heat → hyperthermia → vasodilatation, dehydration, seizures; maintain core at 36.5–37.5°C
- Cold stress cascade: ↓ temperature → ↑ metabolic rate → ↑ O2 consumption → hypoxemia → ↑ anaerobic metabolism → metabolic acidosis → pulmonary vasoconstriction → worsening hypoxemia; a vicious cycle
- Glucose depletes rapidly during cold stress (burned in brown fat thermogenesis) → hypoglycemia → seizures; monitor glucose and feed early/frequently
Key Definitions
Term
Neutral Thermal Environment
Example
Preterm infant in an incubator maintained at 35°C environmental temperature to maintain core of 37°C without active shivering or sweating
Definition
The ambient temperature at which the newborn expends minimal metabolic energy to maintain core body temperature (36.5–37.5°C); achieved through incubators, radiant warmers, or skin-to-skin care.
Term
Cold Stress
Example
Preterm infant left exposed in delivery room → core temperature drops to 35°C → increased O2 demand, shunting to brown fat → hypoglycemia and poor feeding
Definition
Sustained hypothermia or non-shivering thermogenesis response to cold; increases metabolic rate, oxygen consumption, and glucose demand; can lead to metabolic acidosis, hypoglycemia, and apnea.
Term
Brown Fat (Brown Adipose Tissue)
Example
Newborn's brown fat deposits around the neck, axillae, and between scapulae burn to generate heat; depleted rapidly if cold stress occurs
Definition
Specialized fat tissue that generates heat through non-shivering thermogenesis (uncoupling protein UCP-1); abundant in term infants, minimal in preterm; primary heat source in newborns.

Section Title
Intraventricular Hemorrhage (IVH) & Other Preterm Complications
Important Facts
- IVH: most common in infants <32 weeks; germinal-matrix vessels rupture with hypoxia, hypertension, or sudden hypotension; occurs in first 72 hours of life usually
- IVH Grades (Papile): Grade I (subependymal only), Grade II (into lateral ventricles), Grade III (ventricular dilation), Grade IV (periventricular hemorrhagic infarction)
- IVH signs: subtle initially (lethargy, poor feeding); progressive: bulging fontanel, full anterior fontanel, seizures, apnea, bradycardia, pupil changes, coma; many infants asymptomatic until neuroimaging
- IVH prevention: avoid hypoxia/hypercapnia, maintain stable blood pressure, gentle handling, avoid rapid fluid boluses, head midline (not rotated), elevate head 20–30 degrees
- NEC: risk factors are prematurity, LBW, feeding advancement too rapidly, patent ductus arteriosus (PDA), sepsis, and intrauterine growth restriction
- NEC prevention: slow advancement of feeds (20–25 mL/kg/day initially), maintain minimal enteral nutrition if feeds held, use breast milk (protective), strict hand hygiene, avoid unnecessary antibiotics (disrupts gut flora)
- NEC staging (modified Bell): Stage I (suspected NEC — symptoms only), Stage II (definite NEC — pneumatosis on X-ray), Stage III (advanced NEC — perforation, pneumoperitoneum)
- NEC management: keep NPO, insert NG tube, IV fluids, broad-spectrum antibiotics (ampicillin + gentamicin + clindamycin or metronidazole for anaerobes), abdominal imaging (serial films for pneumoperitoneum), close monitoring; surgery if perforation/deterioration
- ROP: risk from high oxygen exposure and rapid SpO2 fluctuations; target SpO2 85–95% in preterm (avoid >95% and <85%); pulse oximetry SATURATION targets, not PaO2
- ROP: screening required for all infants <30 weeks GA or <1,500 g (and selected infants 30–32 weeks/1,500–2,000 g if unstable); screening starts at 4 weeks postnatal age or 31 weeks postmenstrual age (whichever is later)
- ROP treatment: anti-VEGF agents (bevacizumab, ranibizumab, aflibercept) or ablative therapy (laser) for high-risk disease; ophthalmology follow-up essential
Key Definitions
Term
Intraventricular Hemorrhage (IVH)
Example
Grade III IVH: bleeding extends into the lateral ventricles; infant shows decreased consciousness, bulging fontanel, seizures at day 2–3 of life
Definition
Bleeding into the ventricular system of the brain; occurs in preterm infants due to fragile germinal-matrix capillaries and fluctuating cerebral blood flow.
Term
Germinal Matrix
Example
Preterm infant at 26 weeks with severe respiratory distress and fluctuating blood pressures → germinal-matrix vessels rupture → IVH
Definition
Highly vascular region of the developing brain (subventricular zone) present primarily before 32 weeks; vessels are fragile and prone to rupture with hypoxia, hypertension, or rapid volume shifts.
Term
Necrotizing Enterocolitis (NEC)
Example
Preterm infant 5 days post-birth on gavage feeds; sudden onset of abdominal distension, green gastric residuals, bloody stools, lethargy → NEC stage II
Definition
Inflammation and necrosis of the intestinal mucosa; occurs primarily in preterm/LBW infants; manifests as abdominal distension, bloody stools, feeding intolerance, and sepsis.
Term
Retinopathy of Prematurity (ROP)
Example
Preterm infant 28 weeks, SpO2 kept at 98–100% for weeks → ROP stage III with plus disease; requires anti-VEGF therapy
Definition
Abnormal retinal vascularization in preterm infants exposed to high oxygen and rapid oxygen fluctuations; can progress to retinal detachment and blindness.

Section Title
Family Support, Parental Education & Discharge Planning
Important Facts
- HIGH-RISK NEWBORN PARENTS face fear, guilt, sleep deprivation, financial stress, and disrupted bonding; emotional support is CORE NURSING CARE
- ENCOURAGE PARENTAL INVOLVEMENT: teach parents feeding, bathing, diaper changes, and infant cues (crying, rooting, sleepiness); involve them in care conferences and discharge planning
- KANGAROO CARE: strongly recommended by WHO, UNICEF, and Philippine DOH for preterm and LBW infants; start as soon as infant is stable (often within first few days); benefits: thermoregulation, improved oxygenation, reduced stress (lower cortisol), faster weight gain, shorter hospitalization, improved breastfeeding
- COMMUNICATION: use plain language (avoid medical jargon), assess parental understanding, provide written materials in Filipino/local language, repeat information frequently (parents are stressed and may not retain information on first telling), normalize parental questions and concerns
- BREASTFEEDING SUPPORT: lactation consultant involvement, skin-to-skin, breast pump education if direct breastfeeding not yet possible, express colostrum early to establish supply, frequent positioning attempts
- DISCHARGE READINESS: infant must be stable on feeds (ad lib or scheduled without gavage), temperature-stable in open crib, no active medical issues, parents confident in care and feeding
- DANGER SIGNS TO TEACH (NLE classic): poor feeding, lethargy, fever (>38°C) or hypothermia (<36.5°C), fast or labored breathing (>60/min at rest), worsening jaundice, fewer wet diapers (<6/day), difficult consolability, seizures, bulging fontanel
- SCREENING FOLLOW-UP: newborn screening (metabolic/hemoglobinopathy) results reviewed before discharge; if screen is positive, repeat at 1–2 weeks; provide parents with written results and follow-up appointment
- IMMUNIZATION CATCH-UP: preterm infants vaccinated per chronologic age, not corrected age (with rare exceptions); give hepatitis B in delivery room, BCG per DOH schedule (currently given at birth or 6 weeks depending on facility policy); other vaccines per 6-week schedule
- FOLLOW-UP APPOINTMENTS: pediatric (2 weeks, 1 month, then per schedule), ophthalmology (ROP screening if preterm), audiology (newborn hearing screening if failed or preterm), neurodevelopmental (high-risk preterm), hepatology (if jaundice >3 weeks), and any specialist consultations from hospital
- HOME SAFETY: safe sleep (supine, firm crib, no bumpers/blankets), car seat installation, prevention of smoke/drug exposure, infection control (hand hygiene, limiting sick visitors), CPR training for parents if high-risk infant
Key Definitions
Term
Kangaroo Care (Skin-to-Skin Contact)
Example
Mother holds preterm infant bare-chested under her clothing for 1–2 hours daily; infant's temperature stabilizes at 37°C, heart rate regularizes, and breastfeeding improves by week 3
Definition
Direct chest-to-chest contact between parent and infant; thermoregulates, stabilizes vital signs, enhances bonding, and improves breastfeeding outcomes.
Term
Family-Centered Care
Example
Mother participates in her preterm infant's baths, diaper changes, and feeding decisions; receives written education on danger signs; has 24-hour phone access to NICU staff
Definition
Care model that recognizes parents as primary caregivers; involves them in all decisions, respects their values, and provides emotional support throughout hospitalization.

Must Remember
- PRETERM = <37 weeks gestation; LBW <2,500g, VLBW <1,500g, ELBW <1,000g. Every system immature: surfactant deficiency → RDS, minimal brown fat → heat loss, weak suck → gavage feeding, fragile germinal-matrix vessels → IVH, immature immune → sepsis risk.
- RDS = SURFACTANT DEFICIENCY. Signs: tachypnea >60/min, grunting, nasal flaring, retractions, cyanosis within hours of birth. TREATMENT: exogenous surfactant (beractant/poractant) + respiratory support. PREVENTION: antenatal betamethasone 12mg IM x2 (24h apart) for preterm birth between 24–34 weeks.
- JAUNDICE WITHIN THE FIRST 24 HOURS IS PATHOLOGIC until proven otherwise — suspect Rh/ABO incompatibility, sepsis, or other disease. Physiologic jaundice appears AFTER 24 hours (day 2–3), peaks day 3–5, resolves by day 7 in term infants.
- Use the BHUTANI HOUR-SPECIFIC NOMOGRAM to determine phototherapy thresholds — TSB value depends on postnatal age in hours AND risk category (low, medium, high). Do NOT use a single fixed number.
- KERNICTERUS RISK: unconjugated bilirubin approaching ~20–25 mg/dL in term infant (much LOWER in preterm/ill infants). Conjugated bilirubin >2 mg/dL or >20% of total is ALWAYS PATHOLOGIC.
- PHOTOTHERAPY NURSING: cover the EYES with opaque patches, UNDRESS for maximum skin exposure (protect genitals), maintain hydration/feeding (loose green stools expected), monitor temperature, reposition every 2 hours, check TSB in subdued light (avoid room light falsely lowering readings).
- NEONATAL SEPSIS: signs are SUBTLE and NONSPECIFIC — think 'the baby just isn't doing well.' Often HYPOTHERMIA (not fever), poor feeding, lethargy, tachypnea/apnea, bradycardia, hypotonia, mottled skin. Early-onset: GBS + E. coli; empiric ampicillin + gentamicin after cultures. Prevention: intrapartum antibiotics for GBS-positive mothers.
- TRACHEOESOPHAGEAL FISTULA (EA/TEF): the '3 Cs' — COUGHING, CHOKING, CYANOSIS with feeding; excessive drooling. Keep NPO, gentle suction, elevate HOB, insert Replogle tube for continuous suction. Do NOT feed.
- DIAPHRAGMATIC HERNIA: scaphoid abdomen, bowel sounds in chest. Do NOT bag-mask ventilate (inflates gut in chest, worsens compression) — INTUBATE immediately and insert OG tube for decompression.
- IDM (INFANT OF DIABETIC MOTHER): MACROSOMIA >4,000g → birth injury risk; HYPOGLYCEMIA within first 1–2 hours (insulin persists after maternal glucose cut off). Monitor glucose frequently, feed early/often. Also watch for hypocalcemia, polycythemia, hyperbilirubinemia, RDS.
Last Minute Tips
- ALWAYS READ THE BHUTANI NOMOGRAM carefully for phototherapy thresholds — it has three risk lines (low, medium, high). Never guess a TSB cutoff; the age in HOURS and the risk category matter. If a question doesn't mention age or risk, calculate from the narrative.
- Distinguish PHYSIOLOGIC from PATHOLOGIC jaundice by the FIRST 24 HOURS rule: if visible within 24 hours → pathologic (investigate immediately). If after 24 hours → likely physiologic (but still monitor). This is an absolute NLE favorite.
- For preterm infants, TACHYPNEA >60/min is RDS until proven otherwise. For term infants, TTN is more likely after elective cesarean. For meconium-stained and post-term, think MAS. Know the CXR pattern: RDS = ground-glass; TTN = fluid in fissures; MAS = patchy infiltrates with hyperinflation.
- OXYGEN TARGETS in preterm: aim for SpO2 85–95% to prevent both hypoxemia (IVH, NEC risk) and hyperoxia (ROP risk). This is NOT a fixed PaO2 goal — watch the saturation monitor, not the blood gas number.
- KANGAROO CARE is testable and DOH-recommended for preterm/LBW infants — know the benefits (thermoregulation, improved oxygenation, bonding, faster feeds, shorter hospital stay) and how to teach parents. It's evidence-based and high-yield for the NLE.
