Neonatal outcome and two-year follow-up after expectant management of second trimester rupture of membranes

Objective: To assess neonatal outcome and 2-year follow-up of pregnancies complicated by second trimester preterm premature rupture of membranes (PPROM). Methods: A retrospective review of obstetric and neonatal records for 87 pregnancies (56 singletons, 6 twins, 1 triplet) with PPROM between 14 + 0 and 24 + 6 weeks of gestation. Patients received antibiotics and steroids for fetal lung maturity once they reached 24 weeks of gestation. Placentas were examined histopathologically. Surviving infants were followed-up at 2 years of age. Results: Median latency from PPROM to delivery was 4 days. Survival rate of 56 singletons was 45% (25/56); and 13 died in hospital. Survival rate of infants discharged from hospital was 23% (12/56). Chorioamnionitis was seen histologically in 42% (5/12) of surviving infants compared with 92% (12/13) of those that died in hospital. Of the 12 surviving infants, 50% had a normal neurological and developmental outcome at 2 years of age. Conclusion: Gestational age, birth weight, and histologic chorioamnionitis have prognostic importance in pregnancies complicated by PPROM. Surviving infants have a 50% chance of achieving an adequate health status at 2 years of age. (C) 2008 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.
