This study aimed to investigate the success rate, complications, and success-related factors of external cephalic version (ECV) of singleton breech pregnancies after 37 gestational weeks without anesthesia.
We studied 40 singleton breech pregnancies in women who underwent ECV without anesthesia after 37 gestational weeks from October 2018 to March 2020. On the basis of success of ECV, the women were divided into two groups of the successful group and the failed group. Various factors were analyzed to determine those that affect the success of ECV.
Of the 40 attempts of ECV, 24 (60.0%) were successful and 16 (40.0%) failed. With regard to success-related factors, parity was significantly different between the two groups, with more multiparous women in the successful group than in the failed group. However, none of the other factors were significantly different between the groups. Fetal outcome was good in all of the cases. Ultimately, 3 cesarean sections were performed in the successful group and 16 were performed in the failed group.
ECV of breech presentation after the 37th week of pregnancy without anesthesia is an effective and relatively safe alternative, and can effectively reduce the cesarean section rate.
本研究旨在探讨孕37周后未行麻醉的单胎臀位妊娠外倒转术（ECV）的成功率、并发症及成功相关因素。
我们研究了2018年10月至2020年3月期间40例孕37周后未行麻醉接受ECV的单胎臀位妊娠女性。根据ECV是否成功，将这些女性分为成功组和失败组。分析各种因素以确定影响ECV成功的因素。
40次ECV尝试中，24次（60.0%）成功，16次（40.0%）失败。在成功相关因素方面，两组间产次有显著差异，成功组经产妇多于失败组。然而，其他因素在两组间均无显著差异。所有病例的胎儿结局均良好。最终，成功组进行了3例剖宫产，失败组进行了16例剖宫产。
孕37周后未行麻醉的臀位外倒转术是一种有效且相对安全的选择，可有效降低剖宫产率。
