孕晚期臀位孕妇外倒转术失败的影响因素分析

Influencing factors of failure of external cephalic version in pregnant women with breech presentation in the third trimester

目的:分析孕晚期臀位孕妇外倒转术失败的影响因素。方法:选取2018年1月至2020年10月在本院行外倒转术的80例孕晚期臀位孕妇为研究对象,根据术后结果分为成功组(56例)和失败组(24例)。比较两组临床资料,并分析外倒转术失败的影响因素。结果:孕晚期臀位孕妇外倒转术成功率为70.00%;两组皮下脂肪厚度、臀先露类型、胎盘附着位置比较差异有统计学意义(P<0.05);logistic回归分析显示皮下脂肪厚度、臀先露类型、胎盘附着位置是孕晚期臀位孕妇外倒转术失败的影响因素(P<0.01)。结论:皮下脂肪过厚、复合臀、非后壁胎盘是孕晚期臀位孕妇外倒转术失败的危险因素。

Objective:To analyze the influencing factors of the failure of external cephalic version in pregnant women with breech presentation in the third trimester.Methods:80 pregnant women with breech presentation in the third trimester who underwent external cephalic version in our hospital were selected from January 2018 to October 2020.According to the postoperative results,they were divided into the success group(n=56)and the failure group(n=24).The clinical data were compared between the two groups,and the influencing factors of the failure of external cephalic version were analyzed.Results:The success rate of external cephalic version of breech position in the third trimester was 70.00%;there were significant differences in subcutaneous fat thickness,type of breech presentation,and placental attachment site between the two groups(P<0.05);logistic regression analysis showed that the thickness of subcutaneous fat,the type of breech presentation,and the placental attachment site were the influencing factors of the failure of external cephalic version in these pregnant women(P<0.01).Conclusion:Excessive subcutaneous fat thickness,compound breech presentation and non-posterior placenta are the risk factors for the failure of external cephalic version in pregnant women with breech presentation in the third trimester.
