摘要
目的:分析足月及近足月臀位外倒转术(ECV)的临床应用价值及其影响因素。方法:选择2019年1月-2020年3月在我院定期产检、足月及近足月经超声确诊臀位妊娠的93例孕妇作为研究对象,42例选择ECV术矫正胎位,51例接受膝胸卧位矫正胎位,选择同期42例足月头位妊娠待分娩的孕妇作为对照组,分析2种矫正方法胎位复位成功率的差异,复位成功孕妇分娩结局与对照组孕妇分娩结局的差异,ECV复位成功影响因素。结果:ECV组最终复位成功率为83.33%,高于膝胸卧位组47.06%(P<0.05);ECV复位成功组、膝胸卧位复位成功组、对照组阴道分娩率比较,差异无统计学意义(P>0.05);三组新生儿1min Apgar评分与5min Apgar评分比较,差异无统计学意义(P>0.05);ECV成功率与是否存在脐绕颈、先露是否入盆、是否使用宫缩抑制剂、是否使用椎管麻醉密切相关(P<0.05)。结论:足月及近足月臀位行ECV成功率高,有助于提高阴道分娩率,对孕妇及胎儿无明显不良影响。
Objective:To analyze the clinical application value and influencing factors of success rate of external cephalic version(ECV)for breech pregnancies in the third trimester.Methods:From January 2019 to March 2020,93 pregnant women with breech pregnancy diagnosed by ultrasound in the third trimester were selected as the study objects,42 cases were treated by ECV,51 cases were treated by knee and chest position,42 cases were treated by expectant delivery of third trimester head pregnancy as the control group,and the difference of reduction success rate between the two methods was analyzed.The difference of delivery outcome between pregnant women and control group,and the influencing factors of ECV success rate.Results:The final reduction success rate of ECV group was 83.33%,which was higher than that of knee chest position group 47.06%(P<0.05);The rate of vaginal delivery was no significant difference among the three groups(P>0.05);Apgar score of 1 minute and 5 minutes were no significant difference among the three groups(P>0.05);The success rate of ECV was closely related to the presence of umbilical cord around the neck,pelvic presentation,use of uterine contraction inhibitors and spinal anesthesia(P<0.05).Conclusion:The success rate of ECV in the third trimester is higher,which is helpful to improve vaginal delivery and has no obvious adverse effect on pregnant women and fetus.
