Paediatrics Short Notes - 5 Marks Format

Exam-oriented, in a concise Ghai-style layout. Drug doses and immunization schedules should be cross-checked with the current national/IAP recommendation used by your university.

1. Neonatal Jaundice

Definition: Yellow discoloration of skin and sclera due to hyperbilirubinemia in the newborn.

Types

  1. Physiological jaundice
    • Appears after 24 hours.
    • Peaks on day 3-5 in term babies, day 5-7 in preterm babies.
    • Resolves by 10-14 days.
  2. Pathological jaundice
    • Appears within first 24 hours.
    • Rapid rise in bilirubin, usually >5 mg/dL/day.
    • Total serum bilirubin >95th centile for age.
    • Persists >14 days in term or >21 days in preterm infant.
    • Conjugated bilirubin >2 mg/dL or >20% of total bilirubin.

Causes

  • Unconjugated: Physiological, prematurity, poor feeding, breast milk jaundice, hemolysis due to Rh/ABO incompatibility, G6PD deficiency, cephalhematoma, sepsis, hypothyroidism.
  • Conjugated: Neonatal hepatitis, biliary atresia, sepsis, metabolic disorders.

Evaluation

  • History: onset, feeding, maternal blood group, sibling history.
  • Examination: extent of jaundice, pallor, hepatosplenomegaly, sepsis.
  • Investigations: serum bilirubin, blood group and Coombs test, Hb/PCV, reticulocyte count, peripheral smear, G6PD assay, sepsis screen where indicated.

Management

  • Ensure adequate breastfeeding and hydration.
  • Phototherapy according to age-specific bilirubin charts.
  • IVIG may be used in isoimmune hemolysis with rising bilirubin despite intensive phototherapy.
  • Exchange transfusion for severe hyperbilirubinemia or signs of acute bilirubin encephalopathy.
  • Treat the underlying cause.

Complication

  • Acute bilirubin encephalopathy and kernicterus.

2. Newborn Resuscitation

Aim: Establish effective breathing and circulation at birth.

Initial assessment

Ask:
  1. Is the baby term?
  2. Is there good tone?
  3. Is the baby breathing or crying?
If yes to all: routine care, warmth, delayed cord clamping as appropriate, skin-to-skin contact and breastfeeding.

Initial steps for a non-vigorous baby

  • Provide warmth under radiant warmer.
  • Position airway in neutral position.
  • Dry and stimulate.
  • Clear secretions only if they obstruct the airway.
  • Assess breathing and heart rate.

Positive-pressure ventilation (PPV)

Indication: Apnea, gasping, or heart rate <100/min.
  • Start PPV with appropriately sized mask, preferably with room air in term baby.
  • Give ventilation at 40-60 breaths/min.
  • Reassess after 30 seconds of effective ventilation.
  • Correct ventilation by mask adjustment, repositioning airway, suction if needed, opening mouth, increasing pressure, and alternative airway.

Chest compression

Indication: Heart rate <60/min after 30 seconds of effective PPV.
  • Use two-thumb encircling technique.
  • Compression: ventilation ratio = 3:1.
  • Give 90 compressions and 30 breaths/min, total 120 events/min.
  • Use 100% oxygen during compressions.

Drugs

Epinephrine: If HR remains <60/min despite 60 seconds of effective ventilation plus compressions.
  • IV/umbilical venous dose: 0.01-0.03 mg/kg of 1:10,000 solution.
  • Consider volume expansion with normal saline, 10 mL/kg, if blood loss or shock is suspected.

Post-resuscitation care

  • Monitor temperature, respiration, glucose, perfusion, seizures and oxygen saturation.
  • Observe for hypoxic ischemic encephalopathy.

3. Neonatal Sepsis

Definition: Systemic infection occurring in the first 28 days of life.

Classification

  1. Early-onset sepsis: Usually within first 72 hours of life. Acquired vertically from mother.
  2. Late-onset sepsis: After 72 hours. Usually hospital-acquired or community-acquired.

Risk factors

  • Prematurity, low birth weight.
  • Prolonged rupture of membranes >18 hours.
  • Maternal fever/chorioamnionitis.
  • Prolonged labor, foul-smelling liquor.

Clinical features

  • Poor feeding, lethargy, irritability.
  • Temperature instability, hypothermia or fever.
  • Respiratory distress, apnea, cyanosis.
  • Vomiting, abdominal distension.
  • Jaundice, hepatosplenomegaly.
  • Poor perfusion, prolonged capillary refill, shock.
  • Seizures.

Investigations

  • Blood culture before antibiotics.
  • CBC: abnormal total leukocyte count, ANC, immature/total neutrophil ratio.
  • CRP, procalcitonin.
  • CSF examination if meningitis is suspected and baby is stable.
  • Urine culture in late-onset sepsis.
  • Chest radiograph if respiratory symptoms.

Management

  • Admit and provide supportive care: warmth, oxygen, fluids, glucose, correction of shock.
  • Send cultures before treatment.
  • Empirical antibiotics according to local policy:
    • Common initial regimen: ampicillin/penicillin plus gentamicin.
    • Alternative according to unit antibiogram: cefotaxime-based regimen where indicated.
  • Modify antibiotics according to culture sensitivity.
  • Treat meningitis for longer duration.

Prevention

Other IAP catch-up schedules depend on age at starting vaccination.

Catch-up vaccination

    • Insulin 0.1 unit/kg IV with glucose.
    • Nebulized salbutamol.
    • Sodium bicarbonate if metabolic acidosis is present.
  6. Remove potassium:
    • Loop diuretic if renal function permits.
