Background We aimed to analyze the success rate of external cephalic version (ECV) for breech presentations performed in our center between March 2011 and March 2016. We evaluated factors related to a successful ECV, delivery mode, complications and newborn status after ECV. Methods Analysis of assembled data of 327 consecutive ECVs in the third trimester was done. Results The total success rate was 56.6%. After a successful ECV, 85.9% of the fetuses were delivered vaginally. Logistic regression analysis of background factors leading to a successful ECV showed that tocolysis with ritodrine and anterior placenta were each significantly correlated with the rate of successful version. No severe complications were registered during the ECVs, and all babies had normal Apgar scores at delivery. Conclusion These findings suggest that attempting an ECV in breech presentations, once or even twice, seems to be an appropriate management given that a successful ECV decreases the rate of cesarean section in this group of patients and by doing so, it might also decrease the risk of cesarean sections in future pregnancies.
背景 我们旨在分析 2011 年 3 月至 2016 年 3 月期间在我们中心进行的外倒转术（ECV）治疗臀位的成功率。我们评估了与 ECV 成功相关的因素、分娩方式、并发症和 ECV 后新生儿情况。 方法 对 327 例连续 ECV 进行了回顾性分析。 结果 总成功率为 56.6%。ECV 成功后，85.9%的胎儿经阴道分娩。导致 ECV 成功的背景因素的逻辑回归分析表明，用利托君进行保胎和前置胎盘与成功转位的比例均有显著相关性。ECV 期间未发生严重并发症，所有婴儿分娩时的 Apgar 评分均正常。 结论 这些发现表明，对于臀位，尝试单次或甚至两次 ECV 似乎是一种合适的处理方法，因为 ECV 成功可降低该组患者的剖宫产率，从而降低未来妊娠的剖宫产率。
