Late presentation of neonatal omphalitis following dry cord care

摘要

Neonatal omphalitis is a rare infection in neonates, with an estimated overall incidence of 0.2% to 0.7% in industrialized nations. It has a notable mortality risk, usually secondary to necrotizing fasciitis. In cases of omphalitis, Staphylococcus aureus is the most frequently reported organism. Common risk factors include low birth weight, prolonged rupture of membranes, and chorioamnionitis. The umbilical cord stump is quickly colonized shortly after delivery, usually with nonpathogenic bacteria. The now common practice of rooming-in (newborns staying in the room with their mothers) is protective for infants, allowing them to become colonized with nonpathogenic bacteria from their mother versus acquiring potentially pathogenic organisms from elsewhere in the hospital environment.
