目的探讨脐带绕颈对分娩方式及围产儿的影响。方法以我院2012年1月至今收治的脐带绕颈500例头位妊娠产妇为观察组,其中脐带绕颈1周405例为观察1组,脐带绕颈2周及2周以上95例为观察2组;随机选取同期无脐带绕颈的头位妊娠产妇500例为对照组,分析脐带绕颈分娩方式的选择及对围产儿的影响。结果观察1组、观察2组及对照组的脐带平均长度分别为64.5±5.0cm、75.6±4.8cm、50.5±5.6cm。观察1组与观察2组之间以及观察组与对照组之间脐带长度比较,差异有统计学意义(P<0.05)。胎儿窘迫、新生儿窒息的发病率在观察1组和对照组间非常接近,差异无统计学意义(P>0.05);观察2组发病率高于对照组,差异有统计学意义(P<0.05)。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、新生儿窒息发生率越大。
Objective To investigate the effects of umbilical cord around the neck on the mode of delivery and perinatal children. Methods 500 cases of uterine cord around the neck from January 2012 to January were treated as the observation group. 405 cases of umbilical cord around the neck for one week and 95 cases of umbilical cord around the neck for 2 weeks and more than 2 weeks were observed 2 groups randomly selected 500 cases of pregnant women of the first position around the neck without cord around the same period as the control group to analyze the choice of umbilical cord around the mode of delivery and the impact on perinatal children. Results The average length of umbilical cord in observation group 1, observation group 2 and control group were 64.5 ± 5.0cm, 75.6 ± 4.8cm and 50.5 ± 5.6cm respectively. There were significant differences in umbilical cord length between observation group 1 and observation group 2 and between observation group and control group (P <0.05). The incidence of fetal distress and neonatal asphyxia was very close between the observation group 1 and the control group, with no significant difference (P> 0.05). The incidence of observation group 2 was higher than that of the control group (P <0.05) ). Conclusion The umbilical cord around the neck and the length of the umbilical cord has a certain relationship, the umbilical cord is too long lead to the neck around the neck of the basic factors, the umbilical cord around the neck more, then the fetal distress, the greater the incidence of neonatal asphyxia.
