Management of asymptomatic term neonates whose mothers received intrapartum antibiotics--Part 1: Rationale for intrapartum antibiotic therapy.

Abstract

The evaluation of the potentially septic newborn is often a source of frustration for practitioners. In the past, it has often been standard practice to evaluate and treat empirically all neonates whose mothers received antibiotics during labor, regardless of whether the infant had any signs or symptoms suggestive of infection. With the advent of recommendations for intrapartum antibiotic therapy to prevent early-onset neonatal group B streptococcal infections, this strategy is no longer practicable because too many infants would thus be evaluated and treated needlessly. This two-part review addresses the issues involved in managing asymptomatic newborns whose mothers received intrapartum antibiotics. This first part reviews the rationale behind strategies for preventing intrapartum transmission of bacterial infection. The administration of intravenous antibiotics to laboring mothers appears to reduce the incidence of group B streptococcal infections in neonates. Additionally, intrapartum antibiotic therapy for maternal chorioamnionitis may inhibit transmission of infection to the infant. Part 2--to be published separately--will address the evaluation and management of the newborn.
