What constitutes proper management for the singleton baby who presents by the breech at term has remained one of the most contentious subjects in obstetric practice. Perinatal morbidity and mortality are much higher in breech than in cephalic presentation. Elective caesarean section has been increasingly used in an attempt to improve the perinatal outcome. But caesarean section has immediate and late maternal complications. Some of these complications can be catastrophic. External cephalic version (ECV) at term, under tocolysis if necessary, will reduce the incidence of vaginal breech delivery and the incidence of caesarean section. Where ECV fails, the use of a selective management protocol will allow trial of breech labour in suitable cases, thus further reducing the incidence of elective section. Symphysiotomy may save the life of the baby whose head is trapped by disproportion.
对于足月臀位单胎婴儿,何种管理方式才恰当,一直是产科实践中最具争议的话题之一。臀位分娩时围产期发病率和死亡率远高于头位分娩。为改善围产期结局,选择性剖宫产的应用越来越多。但剖宫产存在近期和远期的母体并发症。其中一些并发症可能是灾难性的。足月时,必要时在宫缩抑制剂的作用下行外倒转术(ECV),可降低阴道臀位分娩的发生率和剖宫产率。若外倒转术失败,采用选择性管理方案可在合适病例中尝试臀位分娩,从而进一步降低选择性剖宫产的发生率。耻骨联合切开术可挽救因头盆不称而胎头嵌顿的婴儿生命。
