Omphalitis

Last edited: 4/15/2026

Overview

Omphalitis refers to inflammation of the umbilical stump, often observed in neonates, typically within the first few weeks after birth, and can range from superficial to severe systemic infection 1.

Diagnosis

  • Clinical signs include redness, swelling, and discharge from the umbilical stump 1.
  • Microbiological cultures are essential for identifying pathogens 1.
  • Imaging is not typically required unless there is suspicion of deeper tissue involvement or systemic spread 1.

    • Management

  • Antibiotics: Initiate broad-spectrum antibiotics (e.g., ampicillin and gentamicin) pending culture results 1.
  • Local Care: Maintain meticulous umbilical stump care, including regular cleaning and drying 1.
  • Surgical Intervention: Consider surgical exploration if there is evidence of necrotizing fasciitis or abscess formation 1.

    • Special Populations

  • Pregnancy: Not applicable as omphalitis primarily affects neonates 1.
  • Pediatrics: Neonates are at highest risk; close monitoring and prompt intervention are crucial 1.
  • Elderly: Not typically applicable as omphalitis is rare outside neonatal period 1.
  • Comorbidities: No specific guidance provided in the abstracts; manage based on underlying conditions 1.

    • Key Recommendations

  • Perform microbiological cultures to guide targeted antibiotic therapy (Evidence: Moderate 1).
  • Initiate empirical broad-spectrum antibiotic therapy in suspected cases (Evidence: Moderate 1).
  • Ensure meticulous local care of the umbilical stump to prevent infection spread (Evidence: Expert opinion 1).
