251例头位胎儿脐带缠绕的临床分析

Clinical analysis of 251 fetus of cord nuchal cord

目的探讨脐带绕颈对围产儿的影响。方法选择脐带绕颈251例进行分析:(1)分析脐带长度与脐带绕颈的关系;(2)比较脐带绕颈与不绕颈者对围产儿影响;(3)比较脐带绕颈周数对围产儿影响。结果脐带过短无1例发生脐带绕颈,脐带过长组的脐带绕颈周数多于脐带正常长度组,两组比较有显著差异(P<0.01)。脐带绕颈的胎儿窘迫率为36.65%,窒息率为17.39%。结论脐带绕颈与脐带长度有一定的关系,脐带过长是导致脐带绕颈的基本因素。脐带绕颈周数越多,则胎儿窘迫、死胎、窒息发生机率越大。

Objectives To assess effect of nuchal cord on perinatal infant. Methods Retreopective analysis of 294 clinical records was employed of assess ： （ 1 ） The correlation of cord length and nuchal cord neck （2） Perinatal conseguence with as without nuchal cord. （3） Contrest the number of cord entanglement neck with the effect on perinatal infants. Results There wasn＇t cord entanglememt in short cord group. There were more cycles of cord entanglement in long cord group than those in normal length cord group（P 〈0. 01 ）. In nuchal cord group,the rate of fetal distress was 36. 65%, newborn asphyxia 17. 39%. Conclusion There was a correlation of nuchal cord with cord length. Long cord was mains factors which result in cord entanglement. The more cyeles of cord entanglement were associated with higher rates of fetal distress, fetal death and newborn asphyxia.
