How do you assess a newborn immediately after birth?

Use the β€œInitial 30 seconds – Golden Minute” principle (per NRP 2021).

Model Answer:
Immediately after birth:

  1. Dry and provide warmth.
  2. Clear airway if necessary (mouth β†’ nose).
  3. Assess breathing and tone.
  4. If baby is crying β†’ routine care.
  5. If not breathing β†’ stimulate β†’ start bag-mask ventilation within 1 minute (β€œGolden Minute”).
  6. Clamp and cut cord after 30–60 seconds if baby is stable.

πŸ“˜ Tip: Always mention β€œwarmth β†’ clear β†’ breathe β†’ stimulate β†’ ventilate” β€” it’s the UPSC cue line.

How to do neonatal resuscitation

πŸ’™ NEONATAL RESUSCITATION β€”

Β (Based on NRP 8th Edition, 2021 / IAP-NRP Guidelines)

πŸ”Ή 1️⃣ Initial Steps (within 30 sec – β€œWarm, Dry, Stimulate”)

  • Warm the baby, position head slightly extended.
  • Clear airway if needed (mouth β†’ nose).
  • Dry and gently stimulate.
  • Assess cry, tone, breathing, HR.

πŸ”Ή 2️⃣ If baby not breathing or HR < 100/min β†’ Start PPV

  • Bag-mask ventilation with room air (21% Oβ‚‚).
  • Check chest rise β€” effective ventilation is key.

πŸ”Ή 3️⃣ If HR < 60/min after 30 sec of PPV β†’ Start Chest Compressions

  • Ratio: 3 compressions : 1 breath.
  • Technique: Two-thumb method on lower sternum.
  • Continue for 60 sec, reassess HR.

πŸ”Ή 4️⃣ If HR < 60/min despite ventilation + compressions β†’ Give Epinephrine

  • 0.01–0.03 mg/kg IV (1 : 10 000) via umbilical vein.

πŸ”Ή 5️⃣ Post-Resuscitation Care

  • Maintain warmth, glucose, and oxygen saturation.
  • Monitor for apnea or hypoglycemia.

πŸ’™ Tip: β€œWarm β†’ Ventilate β†’ Compress β†’ Drug.”
(Every 30 seconds, reassess HR & breathing.)

What are the common causes of neonatal jaundice?
  1. Physiological jaundice (after 24 h – peaks day 3–4 – resolves by 10 days).
  2. Pathological:
    • Hemolytic disease (ABO/Rh incompatibility)
    • Sepsis
    • G6PD deficiency
    • Prematurity / breastfeeding jaundice

πŸ“˜ Tip: β€œ< 24 h onset = always pathological.”

How do you manage neonatal jaundice?
  • Assess bilirubin vs age (Bhutani nomogram).
  • Phototherapy – first-line.
  • Exchange transfusion if severe (TSB > 20 mg/dL term / > 15 mg/dL preterm or neurological signs).
  • Maintain hydration and treat cause.

πŸ“˜ Tip: Eye protection + monitor temperature + stop when TSB < 12 mg/dL.

What are the causes of low birth weight (LBW)?
  • Maternal: Malnutrition, anemia, hypertension, infection.
  • Placental: Insufficiency, abruption.
  • Fetal: IUGR, multiple pregnancy, congenital anomalies.

πŸ“˜ Tip: India β‰ˆ 20 % LBW births β€” key indicator of maternal health status.

How do you prevent neonatal sepsis?
  • Clean delivery practices.
  • Early breastfeeding.
  • Cord care with dry technique (no spirit).
  • Hand hygiene for handlers.
  • Prompt treatment of maternal UTI/PROM.
  • πŸ“˜ Tip: Sepsis = preventable by antenatal and intrapartum hygiene.
What are Baby Friendly Hospital Initiative (BFHI) tenets?
  • Early initiation of breastfeeding (within 1 hour).
  • Exclusive breastfeeding for 6 months.
  • Rooming-in & mother–infant bonding.
  • No pre-lacteal feeds / bottle feeding.
  • Support to mothers after discharge.

πŸ“˜ Tip: BFHI = joint WHO–UNICEF initiative (1991).

What are the advantages of breastfeeding?

Model Answer:
For baby:

  • Ideal nutrition β€” correct protein:fat ratio (1 : 4).
  • Passive immunity (IgA, lactoferrin, lysozyme).
  • Protects against diarrhoea, pneumonia, NEC, otitis media.
  • Promotes bonding and jaw development.

For mother:

  • ↓ PPH by oxytocin release.
  • Delays ovulation (lactational amenorrhoea).
  • Lowers breast & ovarian cancer risk.

For society:

  • Economical, hygienic, eco-friendly.

πŸ”ΉTip: Quote β€œexclusive breastfeeding for first 6 months β€” WHO guideline.”

Correct steps of breastfeeding technique

(4 key C’s):

  1. Calm & comfortable posture for mother.
  2. Close contact β€” baby’s whole body facing mother.
  3. Chin-to-breast, mouth wide open, areola inside.
  4. Complete emptying of one breast before shifting to other.

πŸ”ΉTip: β€œGood attachment β†’ more areola visible above mouth.”

Kangaroo Mother Care (KMC)?

Continuous skin-to-skin contact between mother and LBW/preterm baby with exclusive breastfeeding.
Components:

  • Skin-to-skin contact (warmth & bonding).
  • Exclusive breast milk.
  • Early discharge + follow-up.

Benefits:
Maintains temperature, reduces apnea & infection, promotes weight gain, improves survival.

πŸ”ΉTip: β€œKMC = warmth + love + nutrition β€” the best incubator in low-resource settings.”

Define Low Birth Weight (LBW)

Treatment of Neonatal Jaundice
  • Phototherapy: Clue light 460–490 nm (when bilirubin > threshold chart).
  • Exchange transfusion: For severe/rapid rise or hemolytic disease.
  • Treat underlying cause: Infection, hypothyroidism, etc.

πŸ”ΉTip: β€œTarget bilirubin < 15 mg/dL at 72 h in term baby.”

Causes of Dysentery in Children
  • Bacterial: Shigella, E. coli (EHEC), Salmonella, Campylobacter.
  • Parasitic: Entamoeba histolytica.

Management:
Rehydration (ORS), nutrition, zinc 10–20 mg Γ— 14 days, antibiotics if Shigella suspected.

Management of Pneumonia in Child
  • Assess severity (IMNCI): fast breathing, chest indrawing, danger signs.
  • Outpatient: Oral Amoxicillin Γ— 5 days.
  • Severe: IV Ampicillin + Gentamicin.
  • Oxygen, fluids, antipyretics.

πŸ”ΉTip: β€œCough + fast breathing = pneumonia until proved otherwise.”

Management of Diarrhoea in 2-year-old
  • Plan A/B/C as per dehydration.
  • ORS (75 ml/kg), zinc 10 mg < 6 m; 20 mg > 6 m.
  • Continue feeding & breastfeeding.
  • Avoid unnecessary antibiotics.

Side effects: mild fever, irritability, diarrhoea.

πŸ”ΉTip: β€œThree P’s of prevention β€” PCV, Pentavalent, Polio.”

3-year-old with generalized edema – Differentials
  • Nephrotic syndrome (most common).
  • Acute glomerulonephritis.
  • Chronic liver disease.
  • Protein-energy malnutrition.
  • Congestive heart failure.

πŸ”ΉTip: β€œEdema + proteinuria = renal origin until proved otherwise.”

Mnemonic β€” PALE:

  • Proteinuria > 3.5 g/day
  • Albumin ↓ < 2.5 g/dL
  • Lipid ↑ (hypercholesterolemia)
  • Edema (generalized)

Most common type: Minimal Change Disease (MCD).

. Investigations in nephrotic syndrome

Urine protein (3+), microscopy, serum albumin, cholesterol, renal function, ultrasound.

. Management
  • Prednisolone 2 mg/kg/day Γ— 6 weeks β†’ taper.
  • Salt restriction, diuretics for edema.
  • Pneumococcal vaccination.
  • Relapse β†’ cyclophosphamide / Levamisole.
