Omphalitis

Overview

Omphalitis is a serious bacterial infection that affects the umbilical cord stump in newborn infants, typically occurring within the first few weeks of life. This condition represents one of the most significant neonatal emergencies, as it can rapidly progress from a localized infection to life-threatening systemic sepsis. The umbilical cord stump, which remains after the cord is cut at birth, provides an ideal entry point for bacteria due to its moist, protein-rich environment and direct connection to the infant's circulation through the umbilical vessels.

The infection typically begins as a superficial inflammation around the umbilical stump but can quickly spread to deeper tissues, including the umbilical vessels, abdominal wall, and potentially into the bloodstream. Omphalitis occurs more frequently in developing countries where hygiene standards during delivery and cord care may be suboptimal, but it can also occur in developed nations, particularly in premature infants or those with compromised immune systems. The condition has historically been a major cause of neonatal mortality worldwide, though proper hygiene practices and prompt medical treatment have significantly reduced its incidence and severity.

Early recognition and aggressive treatment are crucial for preventing complications, which can include necrotizing fasciitis, abdominal wall abscesses, portal vein thrombosis, liver abscesses, and septic shock. The infection is entirely preventable through proper cord care practices, including keeping the area clean and dry, avoiding the application of potentially contaminated substances, and maintaining good hygiene during handling. Healthcare providers emphasize the importance of parent education regarding proper umbilical cord care and the early warning signs of infection. With prompt recognition and appropriate antibiotic therapy, the prognosis is generally excellent, but delayed treatment can result in serious long-term complications or death.
