Breech presentation occurs in 3-5% of deliveries and can be managed by either a trial of vaginal breech delivery (TOVBD), external cephalic version (ECV) or Caesarean section. A postal questionnaire was completed by 82% of Scottish consultant obstetricians and revealed wide variations in practice. Eighteen percent never offered ECV. Among those who did consensus was lacking on some contraindications. One-quarter sometimes performed ECV before 37 weeks gestations despite the possibility of spontaneous version. Only 70% restricted ECV to one or more designated operators thereby maintaining levels of expertise. Variations were demonstrated in the use of tocolytics, and pre and post procedure investigations. Following failed ECV 28% considered a repeat attempt and 56% a TOVBD. TOVBD was not offered as first line management by one-fifth of respondents. Those who did varied in the pre-procedure investigations performed. Guidelines are required to ensure safe, consistent practice and avoid unnecessary Caesarean sections.
臀位分娩发生率为3% - 5%,可通过阴道试产(TOVBD)、外倒转术(ECV)或剖宫产进行处理。82%的苏格兰产科顾问医生完成了一份邮政问卷调查,结果显示实践差异很大。18%的医生从未提供过外倒转术。在提供外倒转术的医生中,对于一些禁忌症缺乏共识。四分之一的医生有时会在妊娠37周前进行外倒转术,尽管存在自然回转的可能性。只有70%的医生将外倒转术限制由一名或多名指定操作人员进行,从而保持专业水平。在使用宫缩抑制剂以及术前和术后检查方面也存在差异。外倒转术失败后,28%的医生考虑再次尝试,56%的医生考虑进行阴道试产。五分之一的受访者未将阴道试产作为一线处理方法。进行阴道试产的医生在术前检查方面也各不相同。需要制定指南以确保安全、一致的操作,并避免不必要的剖宫产。
