妊娠晚期缩宫素引产成功的影响因素及其分娩结局

Analysis of the factors related to successful induction of pregnant women by oxytocin during the third trimester of pregnancy and their delivery outcomes

目的:探讨妊娠晚期单纯使用缩宫素引产成功的相关因素及其分娩结局。方法:回顾性分析本院2020年8月1日-2020年12月31日有缩宫素引产指征的头位初产妇293例临床资料,二元logistic回归分析方法分析引产成功的影响因素。依据引产成功的临产孕妇是否继续使用缩宫素分为两组,比较其分娩结局。结果:首日缩宫素引产4h宫颈评分改善(≥3分)是阴道分娩成功的影响因素(OR=62.46,95%CI 8.83~471.03);是否继续使用缩宫素引产并不影响剖宫产率(χ^(2)=0.53,P=0.469)。结论:宫颈条件改善情况与引产成功密切相关,继续缩宫素引产不改变剖宫产结局。

Objective:To investigate the factors related to successful induction of pregnant women by oxytocin only during the third trimester of pregnancy and their delivery outcomes.Methods:A retrospective analysis was performed on 293primiparas with fetal position of the head who had indications of oxytocin induction from August 1,2020to December 31,2020.Binary logistic regression analysis was used to analyze the affect factors of successful induction of these women.The women with near the time of labour and successful induction were divided into two groups according to whether they continued to use oxytocin or not,and the delivery outcomes of the women were compared between the two groups.Results:The improvement of cervical score at 4hafter oxytocin induced labor on the first day was the influencing factor of vaginal delivery success(OR=62.46,95%CI 8.83-471.03).Whether to continue using oxytocin during induce labor did not affect the cesarean section rate(χ^(2)=0.53,P=0.469).Conclusion:The improvement of cervical conditions of the women is closely related to their success of induced labor.Continued oxytocin used during induction does not change the outcomes of cesarean section.
