External version with the use of tocolysis is cost-effective and leads to lower perinatal morbidity and a lower cesarean section rate. A study was undertaken to see if version was being practiced in a nonteaching community hospital. One hundred twenty-one breech presentations occurring at 36 or more completed weeks of gestation were reviewed from July 1, 1985 to June 30, 1986. Successful version occurred in 60% of 65 patients; 77% of patients with a successful version delivered vaginally. Six of the remaining 56 patients, who did not undergo attempted version, delivered vaginally with breech presentation. At least 21 patients who delivered by elective cesarean section would have been candidates for external version with tocolysis. Seventeen patients had a cesarean section because a breech presentation was diagnosed in labor.
使用宫缩抑制剂进行外倒转术具有成本效益，可降低围产期发病率和剖宫产率。开展了一项研究，以了解非教学社区医院是否开展了外倒转术。回顾了1985年7月1日至1986年6月30日期间发生在妊娠36周或更完整孕周的121例臀位。65例患者中有60%外倒转术成功；外倒转术成功的患者中有77%经阴道分娩。其余56例未尝试外倒转术的患者中有6例以臀位经阴道分娩。至少有21例行择期剖宫产的患者本可成为使用宫缩抑制剂进行外倒转术的候选人。17例患者因产时诊断为臀位而行剖宫产。
