胎儿脐带绕颈360例临床分析

Clinical Analysis of 360 Fetus of Cord around Neck

目的 探讨脐带绕颈的发生原因、诊断方法、产程处理及对围产儿的影响。方法 选择脐带绕颈 36 0例进行回顾性分析。结果 脐带过短无 1例发生脐带绕颈 ;脐带绕颈 >3周者 ,脐带过长组明显多于脐带正常组 (P <0 .0 1) ,脐带绕颈的胎儿宫内窘迫率为 2 5 .3% ,窒息率为 11.4 % ,脐带绕颈组自然分娩率明显低于对照组 (P <0 .0 1) ,阴道手术产与剖宫产均高于对照组 (P均 <0 .0 1)。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原因。脐带绕颈周数越多 ,则胎儿窘迫。

Objective To demonstrate the causes of cord around neck and its diagnosis, treatment during the labor process and its influence on perinatal infants. Methods 360 fetus of cord around neck were selected to be retrospectively analyzed. Results In the group of excessively short cord, no fetus suffered from cord around neck, but fetus of cord around neck more than 3 circles,in cord longer group ware more than that in normal cord group (P<0.01).The incidence rate of fetal distress and fetal asphyxia in fetus of cord around neck ware 25.3% and 11.4% respectively. The incidence rate of natural labor in group of cord around neck was more lower than the control group(P<0.01).Operations on vagina and cesarean in cord around neck group were more than the control group. Conclusion Cord around neck is related to length of cord. Excessively long cord is the basic factor of cord around neck. The more circles of cord around neck, the more incidence rate of fetal distress and fetal asphyxia.
