Reported are 172 patients considered for external cephalic version at gestational age greater than 37 weeks. Their outcome was compared with 40 similar patients in whom external version was not attempted. One hundred fifty-eight patients had attempted version, and success was achieved in 122 (77%). Intrapartum vertex presentation occurred in 12% of the control population and in 77% of the version patients. Cesarean section was performed in 80% of the control patients and in 32% of the version patients. There were no maternal or fetal complications directly attributable to external cephalic version. Antepartum external cephalic version under tocolysis is associated with a high success rate, an acceptably low rate of complications, and a decreased incidence of cesarean section for breech presentation at term.
报告了172例孕龄大于37周时考虑进行外倒转术的患者。将他们的结局与40例未尝试外倒转术的类似患者进行比较。158例患者尝试了外倒转术，其中122例（77%）成功。对照组12%的患者在分娩时为头先露，外倒转术组为77%。对照组80%的患者和外倒转术组32%的患者进行了剖宫产。没有直接归因于外倒转术的母体或胎儿并发症。在宫缩抑制剂作用下进行产前外倒转术成功率高，并发症发生率可接受，且足月臀位剖宫产的发生率降低。
