External cephalic versions in the study period were performed in a double blind design by 2 experienced practitioners. Sixty-three patients were allocated to treatment with either placebo, ritodrine or hexoprenaline. The main outcome measure studied was successful completion of external cephalic version. Hexoprenaline, but not ritodrine, was statistically more likely to be associated with successful version than placebo (p = 0.04 versus p = 0.22).
在研究期间，外倒转术由两名经验丰富的从业者采用双盲设计进行。63名患者被分配接受安慰剂、利托君或海索那林治疗。研究的主要结局指标是外倒转术成功完成。与安慰剂相比，海索那林而非利托君在统计学上更有可能与倒转成功相关（p = 0.04对比p = 0.22）。
