In the United States, there is a widespread belief that the overall cesarean birth rate is higher than necessary. Efforts are being directed toward decreasing the number of these procedures, in part by encouraging physicians to make changes in their management practices. Because breech presentations are associated with a high rate of cesarean birth, there is renewed interest in techniques such as external cephalic version (ECV) and vaginal breech delivery. The purpose of this document is to provide information about ECV by summarizing the relevant evidence presented in published studies and to make recommendations regarding its use in obstetric practice.
在美国，人们普遍认为总体剖宫产率过高。人们正在努力降低这些手术的数量，部分原因是鼓励医生改变他们的管理实践。因为臀位与高剖宫产率相关，因此对外倒转术（ECV）和阴道臀位分娩等技术重新产生了兴趣。本文件的目的是通过总结已发表研究中提出的相关证据，提供有关 ECV 的信息，并就其在产科实践中的应用提出建议。
