超声引导下行改良外倒转术产妇的妊娠结局分析

Analysis on the pregnancy outcome of parturient women undergoing modified external cephalic version under ultrasound guidance

目的分析在超声引导下行臀位外倒转术(ECV)产妇的妊娠结局。方法回顾性选取2018年5月至2020年5月于深圳市盐田区人民医院建档产检并分娩产妇,妊娠晚期经超声确诊胎位为臀位的106例产妇作为研究对象。根据纠正胎位方法不同分为ECV组(n=49)和传统组(n=57),ECV组产妇在超声引导下行改良外倒转术纠正胎位,传统组则行传统的膝胸卧位纠正胎位。比较两组产妇纠正成功率、妊娠结局及新生儿出生一般情况,并统计ECV组产妇在外倒转术中不良反应发生情况。结果ECV组胎位纠正成功率为83.67%,显著高于传统组的15.79%(P<0.05);ECV组剖宫产率及产程延长发生率均低于传统组,且ECV组自然分娩率为67.35%,明显高于传统组的17.54%(P<0.05);两组新生儿出生一般情况比较,差异无统计学意义(P>0.05);ECV组产妇经超声引导下行改良外倒转术操作过程中不良反应总发生率为4.08%。结论超声引导下行改良外倒转术能有效纠正异常胎位,降低剖宫产率及减少分娩并发症。

Objective To analyze the pregnancy outcome of parturient women undergoing external cephalic version(ECV)under ultrasound guidance.Methods A total of 106 parturient women with breech position confirmed by ultrasound in late pregnancy admitted,examined and delivered in Shenzhen Yantian District People’s Hospital from May 2018 to May 2020 were retrospectively selected as the research objects.According to the different methods of correcting fetal position,they were divided into the ECV group(n=49)and the conventional group(n=57).Parturient women in the ECV group were treated with modified ECV under ultrasound guidance to correct fetal position,while those in the conventional group were treated with conventional knee-chest lying position to correct fetal position.The success rate of correction,pregnancy outcome and general condition of neonatal birth between the two groups of parturient women were compared,and the incidences of adverse reactions(ADRs)in the ECV group were counted.Results The success rate of fetal position correction in the ECV group was 83.67%,significantly higher than 15.79%in the conventional group(P<0.05).The incidences of cesarean section and prolonged labor in the ECV group were both lower than those in the conventional group,and the natural delivery rate in the ECV group was 67.35%,significantly higher than 17.54%in the conventional group(P<0.05).There was no statistically significant difference in general condition between the two groups of neonatal birth(P>0.05).The total incidence of intraoperative ADRs of the ultrasound guided modified ECV in the ECV group of parturient women was 4.08%.Conclusion Modified ECV under ultrasound guidance can effectively correct abnormal fetal position,reduce cesarean section rate and decrease the incidence of delivery complications.
