前次剖宫产后再次妊娠经阴道分娩影响因素的研究进展

Research progress on the influencing factors of vaginal delivery after second pregnancy after cesarean section

妊娠是绝大多数女性都必须经历的过程。自我国实施二孩政策以来,越来越多有前次剖宫产史的孕妇进行再次分娩时,若选择重复性剖宫产(ERCD)会对其身体造成伤害;若选择剖宫产后经阴道分娩(VBAC),则存在失败的可能性,故医患双方需慎重选择分娩方式。本文就国内外对前次剖宫产后再次妊娠经阴道成功分娩影响因素的相关研究进展进行综述,以期为降低我国高剖宫产率的现状和对孕妇的损伤及为前次剖宫产后再次分娩方式的选择提供参考。

Pregnancy is a process that most women have to go through.Since the implementation of the two-child policy in China,more and more pregnant women with the previous cesarean section history give birth again.Elective repeat cesarean delivery(ERCD)can cause harm to the body,vaginal birth after cesarean(VBAC)may fail,so both doctors and patients should carefully choose the delivery method.This paper reviews the research progress on the influencing factors of successful vaginal delivery of second pregnancy after previous cesarean section at home and abroad,in order to provide reference for the current situation of reducing the high rate of cesarean section in China and the injury to pregnant women and the choice of the delivery mode after cesarean section.
