徒手旋转胎头纠正持续性枕后位的临床观察

目的：探讨经阴道徒手旋转胎头术在持续性枕后位产妇中的应用。方法：选择2008年12月～2010年12月持续性枕后位350例,分为A组182例、B组168例,A组经阴道徒手旋转胎头,B组严密观察产程,顺其自然。比较两组分娩结局。结果：A组148例徒手旋转胎头成功,成功率为81.32%,B组37例自然内旋转成功,成功率为22.02%;两组自然分娩率、剖宫产率、新生儿体质量差异有统计学意义（P〈0.05）;两组新生儿窒息、产后出血及软产道裂伤差异无统计学意义（P〉0.05）。结论：活跃期持续性枕后位行徒手旋转胎头术,可显著减低剖宫产率,促进阴道分娩,降低剖宫产率,保障母婴健康。

Clinical observation of manual correction of persistent occipito-posterior position of fetus

Objective： To observe the effects on manual correction of persistent oeeipito-posterior position of fetus. Methods： Three hundred and fifty eases of persistent occipital posterior position from December 2008 to December 2010 were randomly divided into manual correction group （group A, 182 eases） and spontaneous labor group （group B, 168 eases）. Delivery outcome was compared between these two group, s. Results： In group A, manual correction of 148 eases were sueeessful, the success rate was 81.32%. In group B, spontaneous labor of 37 eases were successful, the success rate was 22.02%. There was remarkable difference of natural labor rate, cesarean section rate and body weight of the neonates between the two groups（P〈0.05）, but there was no remarkable difference of neonatal Apgar score, postpartum hemorrhage and genital tract lacerations between the two groups （P〉0.05）. Conclusion： It is worth recommending the use of manual correction of persistent oeeipito-posterior position of fetus beeanse of its health and safety to mothers and infants.
