Clinical context (Premature or term neonate with feeding intolerance, abdominal distension, bloody stools, pneumatosis on imaging, or Bell stage ≥II — medical and surgical emergency requiring NICU-level care)
First-line therapy
NPO + NG decompression + IV fluids + urgent NICU transfer • —
Duration: Until transfer / definitive care · ABCDE; stop all enteral feeds; large-bore NG to low intermittent suction; isotonic IV fluids; maintain temperature; serial abdominal exams and labs (CBC, lactate, blood gas); urgent pediatric surgery/NICU consult — do NOT resume feeds
Ampicillin + gentamicin (empiric per local NICU protocol) • i.v. • 50–50 mg/kg/dose • 3×/day
Max 2000 mg/dose · Duration: 7–14 days · Broad-spectrum empiric coverage for suspected NEC with systemic signs or when perforation cannot be excluded — tailor to cultures and surgical findings at 48–72 h (AAP, APSA, WHO)
• Primary care ABCDE: airway/breathing as needed; IV access; NPO and NG decompression; isotonic fluid resuscitation; correct hypoglycemia and temperature; avoid oral feeds and rectal exams/enemas.
• Urgent referral: all suspected NEC requires NICU and pediatric surgery consultation — do not manage in primary care beyond initial stabilization and safe transport.
• What NOT to do: do not continue enteral feeds; do not give oral antibiotics alone; do not delay transfer for imaging if child is unstable; do not use contrast enema as first-line in acute NEC.
• Monitor for perforation/sepsis: sudden deterioration, abdominal wall erythema, rigidity, pneumoperitoneum, shock — escalate to surgical emergency variant and broaden antibiotics per NICU protocol.
