【摘要】 目的 :探讨脐带绕颈对围产儿的影响。方法 :选择脐带绕颈 2 94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 :脐带过短无一例发生脐带绕颈 ,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 ,P<0 .0 1,有显著差异。脐带绕颈的胎儿窘迫率为2 4.5 % ,窒息率为 10 .2 0 % ,死胎率为 2 .0 4%。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 ,窒息发生机会亦越大。更多还原

【Abstract】 Objectives:To assess effect of nuchal cord on perinatal infant. Methods:Retreopective analysis of 294 clinical records was emploied fo 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 24.5%,newborn asphyxia 10.2%,fetal death 2.04%.Conclusions: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 newbor asphyxia.更多还原
