脐带缠绕的风险因素及围产儿结局

Factors of cord entanglement at risk and the outcomes of perinatal fetuses

目的探讨与脐带缠绕有关的危险因素,以及对围产儿结局的影响。方法回顾性分析5086例产后病例和56例围产儿死亡病例,以及孕产次、孕妇体重、社会职业、新生儿体重、分娩方式、羊水过少和围产儿死亡情况。结果脐带缠绕发生率为30%,其占围产儿死亡原因的27%,脐带缠绕的发生与有无社会职业有明显相关性,但多发生在体重小于3000克和大于4000克组,脐带缠绕合并羊水过少的发生例数明显增多,同时也使剖宫产率升高。结论脐带缠绕应引起产科医生的关注,但复杂性缠绕易引起胎儿猝死,且不宜在产前被发现。

Objective To diseusse the factors which cause cord entanglement at risk, and cord entanglement＇s effects on the outcomes of perinatal fetuses. Methods Retrospectively analyse the total 5086 eases of birth in our hospital between Jan 2004 and Oct 2005, 56 eases of perinatal fetus death included. Results The cord entanglement＇s probability of happening is 30%, which takes up 27% of perinatal fetus death. Whether or not the pregnant women with social jobs, evidently relative to the occurrence of cord entanglement. In addition, cord entanglement often occur on the part of fetal weight below 3000g and above 4000g, the rate of cord entanglement complicating oligohydramnios raises apparently, and cord entanglement makes the rate of eeasarean section becomes higher at the same time. Conclusion Cord entanglement had to be paid attention by obstetricians. However, complicated cord entanglement cause suddenly death of fetus easily and which is difficult be discovered.
