Abstract:
OBJECTIVES: To examine the effects of the oligohydramnios on perinatal outcome and latency period in patients with preterm premature rupture of membranes. METHODS: We performed a retrospective analysis of 98 singleton pregnancies complicated by preterm premature rupture of membranes, with delivery between 26 and 35 weeks' gestation. Amniotic fluid index was determined using transabdominal ultrasound at admission. All medical records of mothers and neonates were reviewed. Oligohydramnios was defined as amniotic fluid index less or equal to 5.0 cm and latency period was defined as time interval from membrane rupture to delivery. Chi-spuare test, Fisher's exact test, Student-t test, Mann-Whitney U test were used for statistical analysis. RESULTS: 1) Of the 98 patients, 59 patients(60%) were oligohydramnios group(AFI< or =5.0) and 39 patients(40%) were non-oligohydramnios group(AFI>5.0). Both groups were similar with respect to selected dermographics, gestational age at rupture of the membranes, chorioamnionitis, 1 min Apgar score and 5 min Apgar score. Patients with oligohydramnios demonstrated a lower gestatoinal age at birth and lower birth weight. There were no statistically significant correlations in neonatal morbidity and perinatal mortality between both groups. 2) For comparing latency period, we excluded deliveries of Cesarean section or induction. Comparing the remained group(25 patients), median of latency period in oligohydramnios group were 41.5 hours and median of latency period in non-oligohydramnios group were 44 hours. There were no statistically significant correlations in oligohydramnios and latency period. CONCLUSION: There were no significant effects of the oligohydramnios on poor perinatal outcome and latency period in patients with preterm premature rupture of membranes
