臀位比头位分娩新生儿死亡率和发病率明显增加。常规在全部或几乎全部病例应用剖腹产或选择性应用阴道分娩或剖腹产的方案能减少产伤和窒息的死亡率和发病率,但前者有较高的母亲病率。 1978年1月1日至1982年12月30日在瑞典Karskrond中心医院有226例孕足月无合并症的单胎臀位分娩。妊娠按Westin氏胎儿骨盆评分分类,以孕37～38周X线骨盆测量和临床资料做为本评分法的基础。最高分为20,当总分>12时,预期可阴道分娩。不管总分,在以下情况常行剖腹产:(1)
Breech than the head childbirth neonatal mortality and morbidity increased significantly. Conventional Caesarean section or selective vaginal delivery or caesarean section in all or almost all cases reduces the morbidity and mortality of birth and asphyxia, but the former has a higher rate of maternal morbidity. Between January 1, 1978 and December 30, 1982, there were 226 single-birth breech births without complications in the Karskrond Central Hospital in Sweden. Pregnancy by the Westin fetal pelvis score classification, pregnancy 38 to 38 weeks of X-ray pelvic measurements and clinical data as the basis for this score method. The highest score is 20, when the total score> 12, is expected to vaginal delivery. Regardless of the total score, caesarean sections are routinely performed in the following situations: (1)
