Effect of intervention time of premature rupture of term membranes on maternal pregnancy outcome
Objective To investigate the effect of different intervention timing on pregnancy outcome of pregnant women with premature rupture of membranes.Methods A total of 90 pregnant women with premature rupture of membrane were selected as the study objects and divided into three groups according to random number table method:A,B and C,with 30 cases in each group.Group A was given intravenously injected oxytocin 2-3 h after membrane rupture,group B was given intravenously injected oxytocin 6-8 h after membrane rupture,and group C was given intravenously injected oxytocin 11-12 h after membrane rupture.The pregnancy outcome of the three groups was compared.Results The postpartum blood loss in group A was lower than that in group B and group C,and the postpartum discharge time was shorter than that in group B and group C(P＜0.05).The uterine productivity and incidence of chorioamniitis in group A were lower than those in group B,but the differences were not statistically significant(P＞0.05).The cesarean section rate and chorioamniotic infection rate of group A were lower than those of group C(P＜0.05).The cesarean section rate and the incidence of chorioamniitis in group B were lower than those in group C,but the differences were not statistically significant(P＞0.05).The incidence of fetal distress,neonatal asphyxia and neonatal infection rate in group A were lower than those in group C(P＜0.05).There were no significant differences in the incidence of fetal distress,neonatal asphyxia and neonatal infection rate between group A and group B,and between group B and group C(P＞0.05).Conclusion The effect of intravenously injecting oxytocin as early as possible is good,which can effectively improve the pregnancy outcome,reduce the incidence of maternal and infant complications,ensure the health of maternal and infant,and is worthy of clinical promotion and application.
