Pediatrics (System-Integrated)
Neonatal respiratory distress: differential and management
— Immediate (delivery room): Perinatal asphyxia, pneumothorax, congenital diaphragmatic hernia (CDH), choanal atresia, severe congenital heart disease
— First few hours: Respiratory distress syndrome (RDS/surfactant deficiency), transient tachypnea of the newborn (TTN), meconium aspiration syndrome (MAS), neonatal pneumonia/sepsis, persistent pulmonary hypertension of the newborn (PPHN)
— Delayed (>24h): Ductal-dependent CHD (closing PDA), late-onset sepsis, aspiration, milk/feeding-related events
— Prematurity <34 weeks → RDS
— Maternal diabetes → RDS even at term, hypertrophic cardiomyopathy
— Cesarean without labor → TTN
— Meconium-stained fluid + post-term → MAS
— Prolonged rupture of membranes >18h, maternal fever, GBS+ untreated → pneumonia/sepsis
— Oligohydramnios → pulmonary hypoplasia
Board pearl: Grunting is expiration against a partially closed glottis to maintain functional residual capacity—an early sign of alveolar collapse (think RDS, pneumonia, TTN). It is never benign and demands evaluation.
Step 3 management: Place on pulse oximetry (preductal—right hand), establish IV access, obtain blood glucose, temperature, CBC, blood culture, and CXR; start empiric ampicillin + gentamicin if sepsis cannot be excluded.
— Gestational age and birth weight: <34 wk biases toward RDS; post-term toward MAS
— Mode of delivery: Elective C-section without labor → TTN (lack of catecholamine surge and thoracic squeeze impairs fluid clearance)
— Rupture of membranes: Duration, fever, foul fluid → chorioamnionitis/pneumonia
— Group B Strep status and intrapartum antibiotic prophylaxis (IAP): Inadequate IAP in GBS+ mom is a major sepsis risk
— Meconium-stained amniotic fluid: Especially thick, particulate → MAS risk
— Maternal conditions: Diabetes (RDS, HCM, hypoglycemia), preeclampsia (IUGR, polycythemia), substance use, SSRIs (PPHN risk)
— Prenatal ultrasound: Polyhydramnios (esophageal atresia, CDH), oligohydramnios (renal anomalies, pulmonary hypoplasia), known cardiac/lung lesions
— APGAR scores and need for resuscitation
— TTN: Tachypnea predominates with minimal hypoxia; resolves within 24–72 hours
— RDS: Progressive worsening over 24–48 hours, then improves; surfactant deficiency
— MAS: Barrel chest, coarse crackles, cyanosis, often requires aggressive support; risk of PPHN
— Pneumonia/sepsis: Temperature instability, lethargy, poor feeding, may look like RDS radiographically
— CHD: Cyanosis poorly responsive to oxygen, differential cyanosis (pre/postductal SpO2 difference >10%)
— Diaphragmatic hernia: Scaphoid abdomen, bowel sounds in chest, immediate distress
Key distinction: TTN improves over hours; RDS worsens for 48–72 hours before improving. The trajectory in the first day often clarifies the diagnosis more than any single CXR.
Board pearl: A baby who pinks up with crying but desaturates at rest = choanal atresia (obligate nasal breathers); confirm by inability to pass NG catheter and place an oral airway.
— Asymmetric breath sounds: Pneumothorax, CDH, mainstem intubation, congenital lung lesion
— Bowel sounds in chest + scaphoid abdomen: CDH (usually left-sided)
— Crackles: Pneumonia, RDS, pulmonary edema from CHD
— Stridor: Laryngomalacia, vocal cord paralysis, subglottic stenosis (not RDS pattern)
— Murmur: May be absent in critical CHD; pansystolic murmur with VSD, continuous murmur with PDA
— Single S2: Pulmonary atresia, truncus arteriosus, severe PPHN
— Hepatomegaly: Right-sided heart failure
— Pre- and postductal SpO2: Right hand vs. either lower extremity; difference >10% or postductal lower → right-to-left shunting at PDA (PPHN, coarctation, interrupted aortic arch)
— Four-extremity blood pressures: Upper > lower by >20 mmHg → coarctation
— Capillary refill: >3 seconds suggests poor perfusion/shock
— Pulses: Weak femorals → coarctation; bounding → PDA with runoff
— Scaphoid abdomen → CDH
— Petechiae, mottling → sepsis or DIC
— Meconium staining of cord/nails → in utero distress
Step 3 management: Always document simultaneous pre- and postductal saturations before labeling distress as "lung disease." A 15% gradient with persistent hypoxia mandates urgent echocardiogram to evaluate for ductal-dependent CHD or PPHN.
Board pearl: Hyperoxia test—100% FiO2 for 10 minutes. PaO2 >150 essentially rules out cyanotic CHD; <100 suggests CHD or severe PPHN.
— CBC with differential: Neutropenia or left shift suggests sepsis; polycythemia (Hct >65%) causes hyperviscosity-induced distress
— Blood culture prior to antibiotics
— CRP and procalcitonin: Trended; not diagnostic alone but support sepsis workup
— Blood glucose: Hypoglycemia mimics distress and worsens it
— Arterial or capillary blood gas: Defines respiratory vs. metabolic acidosis, hypercarbia, oxygenation
— Electrolytes, BUN/Cr: Baseline before fluids and nephrotoxic antibiotics
— Lactate: Marker of tissue perfusion; elevated in sepsis, PPHN, shock
— RDS: Diffuse ground-glass ("reticulogranular") opacities, low lung volumes, air bronchograms
— TTN: Hyperinflation, prominent perihilar streaking, fluid in fissures, mild cardiomegaly
— MAS: Patchy asymmetric infiltrates, hyperinflation, areas of atelectasis, possible pneumothorax
— Pneumonia: Focal or diffuse infiltrates; GBS pneumonia can mimic RDS exactly
— CDH: Bowel loops in hemithorax, mediastinal shift, NG tube curling into chest
— Pneumothorax: Hyperlucent hemithorax, deep sulcus sign, mediastinal shift away
— CHD: Cardiomegaly, abnormal pulmonary vascularity (increased in L→R shunts, decreased in tetralogy/pulmonary atresia), "egg on string" (TGA), "snowman" (TAPVR), "boot-shaped" (TOF)
Key distinction: Group B Strep pneumonia and RDS are often indistinguishable on CXR—both show diffuse granular opacities. Always cover empirically with ampicillin + gentamicin until 48h cultures are negative.
Board pearl: Lung ultrasound is increasingly used in NICUs to differentiate TTN (double lung point) from RDS (diffuse B-lines, consolidation) without radiation exposure.
— Indicated when hypoxia is disproportionate to lung disease, differential cyanosis exists, murmur, abnormal pulses, or no improvement with conventional support
— Identifies structural CHD, quantifies PDA, estimates pulmonary artery pressure (PPHN), assesses ventricular function
— PPHN: Tricuspid regurgitation jet, right-to-left shunting across PDA/PFO, flattened interventricular septum
— Trisomy 21 (AV canal defect), 22q11 deletion (truncus, interrupted arch), CHARGE (choanal atresia), Pierre Robin (airway obstruction)
— Newborn screen results (CF can present as meconium ileus + respiratory issues)
Step 3 management: A term infant with severe hypoxia and a CXR that looks better than the saturations should trigger immediate echo for PPHN or ductal-dependent CHD—do not assume worsening lung disease.
Board pearl: Surfactant protein B deficiency is autosomal recessive, lethal without lung transplant; suspect in term infant with refractory "RDS" and a sibling history.
— Step 1: Warm, dry, position, clear airway only if obstructed, stimulate
— Step 2: If apneic or HR <100 → PPV with 21% O2 (term) or 21–30% (preterm), titrate by SpO2 targets
— Step 3: HR <60 despite 30 sec effective PPV → chest compressions, intubate, escalate O2 to 100%
— Step 4: HR <60 after 60 sec coordinated compressions/ventilation → epinephrine 0.02 mg/kg IV (UVC preferred)
— Mild distress, RR <80, no hypoxia → observation, monitor, consider blow-by O2
— Moderate distress + hypoxia → CPAP 5–6 cmH2O via nasal prongs (especially preterm RDS—reduces intubation)
— Failure of CPAP (FiO2 >0.4, persistent retractions, apnea, hypercarbia) → intubate, mechanical ventilation
— Refractory hypoxia despite ventilation → consider iNO, HFOV, or ECMO
— Preterm RDS requiring intubation, especially <30 weeks, FiO2 >0.3 → early surfactant via INSURE (Intubate-Surfactant-Extubate) or LISA (Less Invasive Surfactant Administration)
Step 3 management: The decision tree—Is there hypoxia disproportionate to work of breathing? Get echo. Is there sepsis risk? Start antibiotics. Is the infant preterm with progressive distress? CPAP early, surfactant if intubated.
CCS pearl: Order pulse oximetry, blood gas, CBC, blood culture, glucose, CXR, IV access, and empiric antibiotics in the same action block when starting a sepsis workup.
— Agents: Poractant alfa (Curosurf, porcine, 200 mg/kg initial), beractant (Survanta, bovine), calfactant
— Indication: Intubated preterm with RDS, FiO2 ≥0.3, or as rescue
— Method: Endotracheal instillation; INSURE or LISA techniques reduce ventilator-induced lung injury
— Adverse effects: Transient hypoxia, bradycardia, pulmonary hemorrhage, endotracheal tube blockage
— Early-onset (<7 days): Ampicillin 50 mg/kg IV q8–12h + gentamicin 4 mg/kg q24h (covers GBS, E. coli, Listeria)
— Late-onset (>7 days, hospital-acquired): Vancomycin + gentamicin or cefepime depending on local resistance
— HSV concern (vesicles, hepatitis, seizures, ill-appearing): Add IV acyclovir 20 mg/kg q8h
— Duration: 48h if cultures negative and infant well; 7–10 days for confirmed pneumonia; 14–21 days for meningitis
— Indication: Term/near-term ≥34 weeks with PPHN, OI >25, despite optimal ventilation
— Start 20 ppm, wean as tolerated; methemoglobinemia monitoring
Board pearl: Any cyanotic neonate with hypoxia unresponsive to oxygen + worsening with PDA closure → start PGE1 immediately, even before echo confirmation. The cost of treating empirically is low; missing ductal-dependent CHD is fatal.
Step 3 management: Always anticipate apnea after PGE1 initiation—have intubation supplies at bedside.
— Indications: Failed CPAP, severe apnea, persistent hypoxia/hypercarbia, need for surfactant, hemodynamic instability
— Tube sizing: 2.5 mm <1 kg, 3.0 mm 1–2 kg, 3.5 mm 2–3 kg, 3.5–4.0 mm >3 kg
— Depth (cm at lip): Weight in kg + 6
— Premedication: Atropine + fentanyl + muscle relaxant (non-emergent)
— UAC: For continuous BP monitoring, frequent ABGs; tip at T6–T9 (high) or L3–L4 (low)
— UVC: Emergent access, medication administration, exchange transfusion; tip at IVC/RA junction
— Complications: Thrombosis, infection, vessel perforation, hepatic necrosis if UVC malpositioned
— Tension pneumothorax (sudden decompensation, asymmetric breath sounds, tracheal deviation, transillumination of chest wall): Needle decompression at 2nd intercostal space midclavicular line, then chest tube
— Conventional: PIP, PEEP 5, rate 30–60, target PaCO2 45–55 (permissive hypercapnia in preterm)
— High-frequency oscillatory ventilation (HFOV): Severe RDS, air leak syndromes, MAS, CDH
— Criteria: ≥34 weeks, ≥2 kg, reversible lung disease, OI >40 despite maximal therapy, failed iNO/HFOV
— Used in severe MAS, PPHN, CDH, sepsis
— Contraindications: IVH grade III/IV, lethal anomalies
— CDH: Stabilize first (often with HFOV/iNO/ECMO), delayed surgical repair
— TEF/EA: Surgical correction within days; replogle tube to decompress upper pouch
— Ductal-dependent CHD: Balloon atrial septostomy (TGA), Norwood/BT shunt (HLHS), etc.
CCS pearl: For a deteriorating intubated neonate, remember DOPE—Displaced tube, Obstructed tube, Pneumothorax, Equipment failure. Run through DOPE before escalating settings.
Board pearl: Bag-mask ventilation in suspected CDH worsens distension of intrathoracic bowel—intubate immediately, place NG/OG tube for decompression.
— Universal RDS risk; antenatal corticosteroids (betamethasone) 24h–7 days before delivery dramatically reduce mortality and severity
— Delivery room CPAP preferred over routine intubation
— Caffeine citrate within first 72h reduces BPD and need for ventilation
— Permissive hypercapnia (PaCO2 45–55) reduces ventilator-induced lung injury
— Vitamin A supplementation reduces BPD in extremely low birth weight infants
— TTN remains common; RDS less severe; antenatal corticosteroids beneficial up to 36+6 weeks for late preterm at risk
— Higher risk of hypoglycemia, feeding immaturity
— RDS even at term (insulin antagonizes cortisol-driven surfactant maturation)
— Hypertrophic cardiomyopathy → outflow obstruction, mimics CHD; usually resolves
— Hypoglycemia, polycythemia → can independently cause distress
— Increased congenital anomaly risk (sacral agenesis, VSD, transposition)
— Aminoglycoside dosing extended (q36–48h <30 weeks); monitor levels
— Avoid NSAIDs (closing PDA with indomethacin/ibuprofen requires careful renal monitoring)
— Avoid sulfa drugs (kernicterus risk via bilirubin displacement)
— Cefriaxone contraindicated in neonates (biliary sludging, calcium precipitation with IV calcium)
— Use cefotaxime or cefepime instead
— Higher risk of polycythemia, hypoglycemia, perinatal asphyxia, MAS
— Often have meconium aspiration in setting of chronic placental insufficiency
Board pearl: Antenatal corticosteroids are the single most impactful intervention in preterm respiratory outcomes; give betamethasone to any mother at risk of delivery 24–36+6 weeks.
Step 3 management: Avoid ceftriaxone in neonates <28 days; substitute cefotaxime or cefepime.
— Meconium passage risk increases sharply; MAS more common
— Placental insufficiency → IUGR, asphyxia
— If meconium-stained fluid + non-vigorous infant → no longer routine intubation/suction; provide PPV per NRP; intubate and suction only if airway obstructed
— Often deceptively well-appearing but at elevated risk for TTN, feeding failure, hypoglycemia, hyperbilirubinemia, sepsis
— Should not be discharged at 24h; require closer monitoring
— Trisomy 21: AV canal defect, duodenal atresia, increased TTN risk
— 22q11.2 deletion (DiGeorge): Conotruncal CHD (truncus, interrupted arch, TOF), hypocalcemia, thymic aplasia
— CHARGE: Coloboma, Heart defects, Atresia choanae, Retardation, Genital, Ear anomalies—respiratory distress often from choanal atresia
— Pierre Robin sequence: Micrognathia, glossoptosis, cleft palate → upper airway obstruction; prone positioning, possible NPA, mandibular distraction
— VACTERL: TEF/EA causes feeding-related cyanosis with first feed; copious oral secretions, inability to pass NG tube
— Severe respiratory distress at birth from pleural effusions, ascites, pulmonary hypoplasia
— Causes: immune (Rh isoimmunization), nonimmune (parvovirus B19, Turner, cardiac, chylothorax)
— Often requires immediate thoracentesis/paracentesis at delivery
— Maternal SSRIs (especially third trimester) → PPHN risk (controversial magnitude), neonatal adaptation syndrome
— Opioid exposure → NAS, not primarily respiratory
Key distinction: A neonate who chokes/cyanoses with first feeding and cannot have an NG advanced is TEF/EA until proven otherwise—stop feeds, place replogle to upper pouch, surgical consult.
Board pearl: Choanal atresia worsens at rest, improves with crying (mouth open); Pierre Robin worsens supine, improves prone.
— Defined as oxygen requirement at 36 weeks postmenstrual age
— Risk factors: extreme prematurity, prolonged mechanical ventilation, high FiO2, infection, PDA
— Prevention: antenatal steroids, surfactant, CPAP > intubation, caffeine, vitamin A, gentle ventilation, fluid restriction
— Long-term: reactive airway disease, pulmonary hypertension, neurodevelopmental delay
— Pneumothorax (5–10% of MAS), pneumomediastinum, pulmonary interstitial emphysema (PIE)
— Higher risk with high PIP, overdistension, MAS
— Failure of postnatal pulmonary vasodilation; right-to-left shunting at PDA/PFO
— Causes: idiopathic, MAS, sepsis, CDH, RDS, asphyxia
— Treatment: iNO, sildenafil, milrinone, HFOV, ECMO
— Preterm complication, especially <32 weeks; germinal matrix fragility
— Grade III/IV (parenchymal extension) carries highest neurodevelopmental risk
— Risk factors: hypotension, fluctuating cerebral blood flow, mechanical ventilation, pneumothorax
— Associated with prematurity, hypoxia, feeding intolerance; pneumatosis intestinalis on KUB
— Excessive oxygen exposure → abnormal retinal vascularization
— Targeted SpO2 90–95% in preterm reduces ROP without increasing mortality
— HIE, IVH, BPD, prolonged hypoxia all contribute to cerebral palsy, cognitive delay, hearing loss
Board pearl: Targeting SpO2 91–95% in preterm infants is the sweet spot—lower (85–89%) increases mortality; higher (>95%) increases ROP.
Step 3 management: Document oxygen saturation targets in NICU orders; nursing should titrate FiO2 to target range, not chase 100%.
— Level I: well-newborn nursery, ≥35 weeks, healthy
— Level II: special care nursery, ≥32 weeks, mild/moderate illness, short-term ventilation
— Level III: NICU, all gestational ages, mechanical ventilation, subspecialty care
— Level IV: regional NICU with surgical, ECMO, complex cardiac capabilities
— Persistent tachypnea >2 hours
— Any supplemental oxygen need
— Apnea, bradycardia, desaturation episodes
— Sepsis evaluation in ill-appearing neonate
— Prematurity <35 weeks
— Hypoglycemia unresponsive to feeds
— Need for ECMO, iNO, complex cardiac surgery, CDH repair, severe IVH
— Use specialized neonatal transport teams; communicate stabilization status, ventilator settings, lines, medications
— Neonatology: All NICU admissions
— Pediatric cardiology: Cyanotic neonate, abnormal pulse oximetry screen, suspected CHD
— Pediatric surgery: CDH, TEF, NEC, congenital lung lesions
— Pediatric ENT/airway: Stridor, choanal atresia, suspected vascular ring
— Genetics: Syndromic features, multiple anomalies
— Palliative care: Lethal anomalies, extreme prematurity at limits of viability
— Update parents frequently, especially before transfer
— Allow brief bonding/holding when stable
— Involve social work for psychosocial support
CCS pearl: When transferring a neonate, ensure airway secured, IV access established, glucose checked, temperature maintained, PGE1 running if indicated, and a verbal handoff to receiving team before mobilization.
Step 3 management: Critical CHD screening with pulse oximetry is mandatory before nursery discharge—failure to screen is a sentinel safety event.
— Preterm <34 weeks (or IDM at term); surfactant deficiency
— CXR: ground-glass, low volumes, air bronchograms
— Worsens 24–48h, improves by 72h
— Treatment: antenatal steroids, CPAP, surfactant
— Term or near-term, especially C-section without labor
— Delayed clearance of fetal lung fluid
— CXR: hyperinflation, perihilar streaking, fluid in fissures
— Self-limited <72h; supportive O2/CPAP
— Post-term, meconium-stained fluid, non-vigorous infant
— CXR: patchy infiltrates, hyperinflation, air leaks
— Risk of PPHN; treatment includes surfactant, iNO, HFOV, possible ECMO
— GBS most common early-onset; E. coli, Listeria, gram-negatives
— Indistinguishable from RDS clinically/radiographically
— Treatment: ampicillin + gentamicin minimum 7–10 days
— Spontaneous in 1–2% term infants; higher with PPV, MAS, RDS
— Sudden decompensation, asymmetric breath sounds, transillumination
— Oligohydramnios sequence, CDH, Potter syndrome (renal agenesis)
— Often lethal if severe; PPHN frequently coexists
— Congenital pulmonary airway malformation (CPAM), pulmonary sequestration, congenital lobar emphysema
— May be diagnosed antenatally; resection if symptomatic
— Term infant with RDS-like picture, refractory to surfactant; genetic testing
Key distinction: Use timing + CXR + maternal history: preterm + steroids/no labor + ground-glass = RDS; term + C-section + hyperinflation = TTN; post-term + meconium + patchy + barrel chest = MAS; any + PROM/fever + diffuse = pneumonia.
Board pearl: When in doubt between GBS pneumonia and RDS, treat both—surfactant + antibiotics—because outcomes diverge sharply with delayed antibiotics.
— Ductal-dependent cyanotic CHD: TGA, tetralogy, tricuspid atresia, pulmonary atresia, HLHS, Ebstein anomaly, TAPVR
— Present with cyanosis poorly responsive to O2, often with PDA closure (hours to days)
— Failed pulse ox screen; differential cyanosis; hyperoxia test PaO2 <100
— Treatment: PGE1, urgent cardiology, possible balloon septostomy
— Coarctation/interrupted arch: Shock with PDA closure, weak femoral pulses, BP gradient
— Polycythemia/hyperviscosity: Hct >65%; plethora, cyanosis, jitteriness; partial exchange if symptomatic
— Severe anemia: Hydrops, twin-twin transfusion, fetomaternal hemorrhage
— Hypoglycemia: Tachypnea, jitteriness, apnea—check glucose in every distressed neonate
— Hypocalcemia: Seizures, irritability
— Inborn errors of metabolism: Urea cycle defects, organic acidemias—present with tachypnea (compensating for metabolic acidosis), lethargy, vomiting after first feeds
— HIE: Apnea, seizures, abnormal tone post-asphyxia; therapeutic hypothermia if ≥36 weeks within 6h
— CNS hemorrhage, meningitis
— Choanal atresia (worse at rest), Pierre Robin (worse supine), vocal cord paralysis, laryngomalacia, vascular ring, subglottic stenosis
— TEF/EA (cyanosis with feeds), CDH (scaphoid abdomen, bowel sounds in chest)
Key distinction: Hyperoxia test rapidly separates cardiac from pulmonary: 100% O2 for 10 min, PaO2 >150 = pulmonary; <100 = cyanotic CHD or severe PPHN.
Step 3 management: In a term neonate decompensating at 24–72 hours with shock and weak pulses, start PGE1 empirically while pursuing echo—coarctation can kill within hours of ductal closure.
— Stable temperature in open crib (typically ≥1800 g)
— Coordinated suck-swallow-breathe, gaining weight on full oral feeds
— Off respiratory support or stable on home oxygen with clear plan
— No apnea/bradycardia events for 5–7 days
— Car seat tolerance test passed for preterm/at-risk infants
— Hearing screen, newborn metabolic screen, critical CHD pulse oximetry completed
— Hepatitis B vaccine administered; eye exam (ROP) if preterm
— Stable low-flow O2 (≤0.5 L/min) with SpO2 ≥92%; parents trained in equipment
— Pulmonology follow-up; periodic SpO2 reassessment to wean
— Caffeine continued for apnea of prematurity until ~34 weeks corrected (often weaned in hospital)
— Iron supplementation 2–4 mg/kg/day for preterm (anemia of prematurity)
— Multivitamin
— Palivizumab (RSV monoclonal) seasonal prophylaxis for qualifying infants: <29 weeks, CLD requiring O2, hemodynamically significant CHD
— Nirsevimab now available for broader RSV prophylaxis
— Follow chronologic (not corrected) age for routine schedule
— Rotavirus has age cutoffs (first dose by 14w6d)
— Breastfeeding strongly encouraged; fortified breast milk for preterm
— Reflux precautions if BPD
— Safe sleep: back to sleep, firm surface, no bed-sharing
— Smoke exposure cessation (worsens BPD, asthma)
— Hand hygiene, RSV season precautions
Board pearl: Preterm infants with BPD remain at elevated risk for RSV-related hospitalization; palivizumab/nirsevimab is a key secondary prevention pillar.
Step 3 management: Schedule first pediatrician visit within 2–3 days of discharge for NICU graduates; weight, jaundice, feeding assessment are critical.
— First visit: 2–3 days post-discharge
— Weekly until weight gain and feeding established
— Standard well-child schedule thereafter, with additional NICU follow-up clinic visits
— Neonatology/high-risk infant clinic: Every 3–6 months through age 2–3 for very preterm or complex graduates
— Ophthalmology (ROP): Preterm <30 weeks or <1500 g—first exam at 4–6 weeks postnatal, then per ROP staging
— Audiology: Initial newborn screen; rescreen at 3 months if failed; comprehensive eval if confirmed loss
— Pulmonology: BPD patients—monitor growth, oxygen needs, exacerbations
— Cardiology: CHD/PDA/PPHN—serial echos
— Developmental pediatrics/early intervention: Refer all extreme preterm and HIE survivors
— Use corrected age until 24 months for assessing milestones in preterm
— Standardized tools: Bayley Scales, ASQ-3
— Early intervention (IDEA Part C) for any delay or qualifying diagnosis
— Use Fenton growth charts for preterm until 50 weeks postmenstrual age, then WHO charts
— Catch-up growth typical by 2–3 years
— Iron status, vitamin D, fortification needs reassessed
— Solid food introduction at corrected age 4–6 months
— NICU follow-up often includes social work, psychology; high rates of parental PTSD and postpartum depression
— Screen mothers for postpartum depression at well-child visits
Step 3 management: Always use corrected gestational age when evaluating growth and development in preterm infants under 2 years—missing this is a classic Step 3 trap.
Board pearl: Refer any preterm <32 weeks or <1500 g, HIE survivors, and IVH grade III/IV automatically to early intervention services—do not wait for delays to manifest.
— Shared decision-making with parents regarding resuscitation
— Outcome data should be presented locally and gestation-specific
— Document antenatal consultation; respect parental values when within accepted standards
— Comfort care vs. full resuscitation discussions before delivery when feasible
— For lethal anomalies or futile cases, palliative care involvement is standard
— Multidisciplinary ethics consultation for disagreement
— Distinguish withholding vs. withdrawing (ethically equivalent but emotionally distinct)
— Surfactant, ECMO, blood transfusion typically covered under general NICU consent
— Jehovah's Witness families: court order may be sought for life-saving transfusion of a minor; document urgency
— Research enrollment (e.g., neonatal trials) requires separate parental consent
— Suspected child abuse, neglect, or non-accidental trauma → state child protective services
— Neonatal abstinence syndrome reporting varies by state—know local statutes
— Birth defect registries (state-mandated)
— Legally mandated in all states; parental refusal handled per state law
— Pulse oximetry critical CHD screen is now standard of care; failure to screen before discharge is a sentinel safety event
— High-risk handoff at NICU discharge: medication reconciliation, equipment training, follow-up appointments confirmed
— Standardized discharge summary to pediatrician within 24h
— Verify car seat fit, home oxygen setup, family CPR training when indicated
— Transparent disclosure to parents of any adverse event (e.g., medication error, missed diagnosis); document conversation
— Mother is the decision-maker antenatally; postnatally, both parents share authority for the neonate
Step 3 management: Confirm pulse oximetry screen, hearing screen, newborn metabolic screen, and HepB vaccine before any nursery discharge—missing any is a documented patient safety failure.
Board pearl: Antenatal consultation at borderline viability should include neonatologist, OB, and family together, with documented decision plan.
Board pearl: "Cyanotic neonate unresponsive to oxygen" + "deteriorating at 1–3 days of life" = ductal-dependent CHD; start PGE1 and call cardiology before further imaging.
Step 3 management: Critical CHD pulse ox screen failure → echocardiogram before discharge—non-negotiable.
Key distinction: Stem timing + maternal history + CXR pattern + response to oxygen is the classic Step 3 four-point puzzle. Match all four.
Board pearl: "Failed pulse ox screen + asymptomatic" still requires echo before discharge—do not reassure based on appearance alone.
Neonatal respiratory distress is a syndrome with a finite differential, and rapid diagnosis hinges on integrating timing of onset, maternal/perinatal history, characteristic CXR pattern, and response to oxygen—then escalating from CPAP/surfactant for preterm lung disease to PGE1 for ductal-dependent CHD, antibiotics for sepsis, and iNO/ECMO for refractory PPHN.
— Preterm + ground-glass CXR + progressive worsening → RDS → antenatal steroids, CPAP, surfactant
— Term C-section + hyperinflation/fissural fluid → TTN → self-limited supportive care
— Post-term + meconium + barrel chest + patchy infiltrates → MAS → watch for PPHN
— PROM/fever/GBS+ + diffuse opacities → pneumonia → ampicillin + gentamicin
— Hypoxia refractory to O2 + differential cyanosis → CHD/PPHN → PGE1 and echo
Board pearl: When timing, history, CXR, and oxygen response disagree, trust the echo—it resolves the cardiac vs. pulmonary dichotomy that drives every neonatal distress vignette on Step 3.
Step 3 management: Start PGE1 empirically in any deteriorating neonate at 24–72 hours with shock, cyanosis, or weak femoral pulses—do not wait for confirmation. The risk-benefit overwhelmingly favors empiric treatment.
