Factors on matemal and fetal outcomes of pregnancy complicated with premature rupture of membrane between 34 and 36~(+6) weeks' gestation

Objective;To study the factors on maternal and fetal outcomes of pregnancy complicated with premature rupture of membrane between 34 and 36 ~(+6) weeks'gestation.Methods:We did a retrospective research on 56 women with premature rupture of membrane between 34 and 36~(+6) weeks' gestation.They were categorized into 2 groups according to the presence of chorioamnionitis. The outcome measures were cesarean section rate,chorioamnionitis,postpartum hospital stay,Apgar score and NICU admission.Results: Chorioamnionitis complicates pregnancy for 10.7%of women with PROM between 34 and 36~(+6) weeks' gestation.NICU admission rate is significantly higher in the group complicated with chorioamnionitis(P = 0.034).There is no statistical difference in cesarean section rate,postpartum hospital stay,birth weight,gender and Apgar score between 2 groups.Logistic regression indicates that low birth weight is correlated with NICU admission.Conclusion:In women with PROM between 34 and 36~(+6) weeks' gestation, chorioamnionitis and low birth weight are risk factors of NICU admission.
