Omphalitis

Clinical Presentation and Approach to Evaluation and Management

Abstract

Omphalitis is an uncommon but potentially serious infection in neonates. Findings include erythema and induration around the umbilical stump, and purulent drainage may be present. Fever and signs of systemic illness may occur, or there may only be signs of localized soft tissue infection. Until recently, there have been very few cohort studies of omphalitis in high-income countries, and no literature was available regarding the incidence of concurrent serious bacterial infection such as meningitis or urinary tract infection. A recent large, multicenter study suggests that most omphalitis presents as localized soft tissue infection, with very low rates of concurrent serious bacterial infection or adverse outcomes. Underlying urachal abnormalities should be considered in the infant with umbilical drainage. Treatment of omphalitis consists primarily of antibiotic administration, with surgical intervention rarely needed. Although antibiotics are typically administered intravenously, there may be a role for oral antibiotics in some lower risk infants with omphalitis.
