【摘要】 目的　调查膝胸卧位校正胎位的方法是否增加脐带异常的发生率,了解其对胎儿状况的影响。方法　回顾性分析5 6 9例记录完善的剖宫产病例,发现晚孕期曾出现过臀位病例136例(含4例横位) ,调查她们是否采用膝胸卧位的方法校正胎位及脐带绕颈发生情况,分析处理因素对胎位校正、脐带绕颈发生率及胎儿/新生儿状况的影响。结果　膝胸位校正胎位成功率5 8.3% ,校正组脐带绕颈发生率与未处理组差异显著(P <0 .0 5 )。但两组胎儿窘迫发生率无显著差异。结论　膝胸位校正胎位的方法成功率较低,使脐带异常发生率增加,但未发现对胎儿产生不良影响。更多还原

【Abstract】 Objective To investigate the abnormality of umbilical cord a nd the condition of the fetus after applying knee-chest postural conversion of t he fetal malpresentation during late term pregnancy.Methods Of 569 cases of cesearen section with complete records during staying in hospital,136 were f ound to have breech presentation (132 cases) and tran sverse lie (4 cases) during 28-34 weeks of pregnancy.The number of cases who ha d tried to convert their fetus’ position using this practice and its outcomes we re analped. No fetus undergoing such management showed intrauterine fetal distr ess.Results The success rate of version using this method was 5 8.3%.There was significant difference between version and no version in occurren ce rate of abnormal umbilical cord (54.1% vs 28.1%) .
