OBJECTIVES
To study the effect of ritodrine tocolysis on the success of external cephalic version (ECV) and to assess the role of ECV in breech presentation at our centre.
MATERIAL AND METHODS
A prospective randomized double-blind-controlled trial comparing ritodrine and placebo in ECV of singleton term breech pregnancy at a tertiary hospital.
RESULTS
Among the 60 patients who were recruited, there was a success rate of 36.7%. Ritodrine tocolysis significantly improved the success rate of ECV (50% vs. 23%; P=0.032). There was a marked effect of ritodrine tocolysis on the ECV success in nulliparae (36.4% vs. 13.0%) and multiparae (87.5% vs. 57.1%). External cephalic version has shown to reduce the rate of cesarean section for breech presentation by 33.5% in our unit.
CONCLUSION
External cephalic version significantly reduced the rate of cesarean section in breech presentation, and ritodrine tocolysis improved the success of ECV and should be offered to both nulliparous and parous women in the case of term breech presentation.
目的
研究利托君抑制宫缩对外倒转术（ECV）成功率的影响，并评估外倒转术在本中心臀先露中的作用。
材料与方法
在一家三级医院进行一项前瞻性随机双盲对照试验，比较利托君和安慰剂在单胎足月臀先露妊娠外倒转术中的效果。
结果
在招募的60例患者中，成功率为36.7%。利托君抑制宫缩显著提高了外倒转术的成功率（50%对23%；P = 0.032）。利托君抑制宫缩对初产妇（36.4%对13.0%）和经产妇（87.5%对57.1%）的外倒转术成功率有显著影响。在本单位，外倒转术已显示可使臀先露剖宫产率降低33.5%。
结论
外倒转术显著降低了臀先露的剖宫产率，利托君抑制宫缩提高了外倒转术的成功率，对于足月臀先露的初产妇和经产妇均应采用。
