Clinical analysis of pregnancy outcome in preterm premature rupture of membranes in 109 patients

Objective:To investigate the pregnancy outcomes of preterm premature rupture of membranes(PPROM).Methods: We included 109 in-patients of PPROM during Jun.2009 and Dec.2010,and allocated them in terms of gestational age to three groups for this retrospective study.Group A(n=44)with gestation of 28 weeks and less than 34 weeks,group B(n=37),34 weeks under 36 weeks and group C(n=28),36 weeks greater than 6 days.The influential factors associated with gestational ages and mode of delivery were analyzed for comparing the results.Results: Neonatal asphyxia was 44.9% for group A,26.83% for group B and 13.8% for group C(P0.05).No significant statistical difference was found in different gestational age with spontaneous delivery or rate of cesarean(P 0.05),and the two modes of delivery had no involvement in asphyxia of newborns(P 0.05).Conclusion: Expectant management is necessary for gestational ages of 28 weeks but less than 34 weeks to reduce the complications of delivery.Besides,right mode of delivery and termination of gestation may lead to desirable pregnancy outcomes.
