Abstract：Objective To investigate the effects of artificial rupture of fetal membrane under epidural labor analgesia in different periods on birth process.Methods A total of 432 primipara who underwent artificial rupture of fetal membranes under epidural labor analgesia in our hospital from January 2016 to March 2017 were emrolled in the study. According to different periods artificial rupture of fetal membranes,the 432 primipara were divided into four groups:the primipara with fetal head appearing but above ischial spine and membrane rupture before cervical dilation deceleration period were divided into A1 group,the primipara with fetal head appearing but above ischial spine and membrane rupture after cervical dilation deceleration period (cervix open 9cm or full open) were divided into A2 group,the primipara with fetal head appearing under ischial spine and membrane rupture before cervical dilation deceleration period were divided into B1 group, and the primipara with fetal head appearing under ischial spine and membrane rupture after cervical dilation deceleration period (cervix open 9cm or full open) were divided into B2 group. The delivery mode,birth process duration,neonatal weigh,main complications of maternal and neonates,courses of caesarean section were obseved and compared among the four groups.Results There was significant difference in cesarean section rate among the four groups(P<0.05).The cesarean section rate in A1 group was the highest, however,there was no significant difference in cesarean section rate among A2, B1, B2 groups (P >0.05). There were significant differences in neonatal weight, asphyxia scores, caput succedaneum formation and postpartum hemorrhage among the four groups (P<0.05). The incidence rate of main complicatins in A1 group was the highest,but there was no significant difference in the incidence rate among A2, B1, B2 groups (P >0.05). Conclusion As compared with the other three groups,the puerpera in A1 group have higher transference cesarean section rate,and the main reasons are protracted active phase to increase fetal distress in uterus,and increase the possibility of severe neonatal asphysia,increase caput succedaneum formation and postpartum hemorrhage. The complications can be avoided if artificial rupture of fetal membrane is performed after cervical mouth is open completely.
