Abstract
OBJECTIVES: To investigate the impact of preterm premature rupture of membranes on neonatal outcome. METHODS: A retrospective study was conducted among singleton pregnancies with or without intact amniochorional membranes. The impact of maternal age, gestational age at birth, 1- and 5-min Apgar scores, birthweight, presence of meconium, use of tocolytics, corticosteroids and antibiotics, mode of delivery, umbilical artery pH, histologic presence of chorioamnionitis, and state of the membranes were analyzed in relation to neonatal outcome. Neonatal outcomes were categorized into: none, presence of respiratory distress syndrome, early neonatal sepsis, neonatal death, and days at neonatal intensive care unit. RESULTS: A total of 180 preterm deliveries with ruptured (n=80) and intact membranes (n=100) constituted the study group (group 1) and the control group (group 2), respectively. Compared with group 2, there were more cases in group 1 of maternal antibiotic use (P<0.001), short-term tocolysis (P=0.03), and histologic chorioamnionitis (P<0.001). Multiple logistic regression analysis showed that gestational age at delivery (P=0.009), 1-min Apgar score (P=0.013), and umbilical artery pH (P=0.05) were the independent factors affecting neonatal outcome. CONCLUSIONS: Neonatal outcome was mainly affected by prematurity rather than by preterm premature rupture of membranes.
