Management of asymptomatic neonates with prolonged rupture of membranes

Abstract

Guidelines for management of asymptomatic term and preterm neonates born to mothers with prolonged rupture of membranes (PROM) have not been clearly established. A survey was conducted to identify current management practice of neonatologists in midwestern states and to find if there is consensus among physicians with regard to management of PROM without choriomnionitis, with chorioamnionitis but without treatment prior to delivery, and with intrapartum maternal antibiotic therapy prior to delivery. One hundred thirty seven responses to the questionnaire were received. Management of asymptomatic at risk neonates varied in different clinical scenarios. Preterm neonates were screened (94% vs 82%, p < 0.001) and treated (64% vs 41%, p<0.001) more often than term babies. In the absence of maternal symptoms of chorioamnionitis, term neonates were usually observed or treated based on screening test results. With maternal symptoms, 94% of physicians ordered screening test. Prematurity and perceived severity of maternal illness significantly influenced the decision to treat routinely irrespective of screening test results. Physicians favour routine treatment of infants born to mothers who had received intrapartum antibiotic therapy; opinion was divided about management of term asymptomatic infant born to mothers with chorioamnionitis without intrapartum antibiotic therapy. Lumbar punctures were not routinely done for term or preterm neonates prior to antibiotic therapy. Further studies are needed to answer questions regarding the benefits and risks of routine therapy of high risk neonates vs routine clinical observation and selective therapy of only infants who develop symptoms.
