脐带缠绕对分娩方式及分娩结局的影响

Effect of cord round the neck on delivery methods and delivery outcomes

目的探讨脐带缠绕对分娩方式及分娩结局的影响。方法住院分娩的脐带缠绕产妇100例为观察组；抽取同期无脐带缠绕的产妇100例为对照组，进行连续胎心宫缩监护，比较2组早期减速（ED）、变异减速（VD）、晚期减速（LD）及胎心基线率（FHR）改变，羊水Ⅱ-Ⅲ度粪染率、新生儿窒息率、分娩方式及脐带长度。结果与对照组比较，观察组VD发生率明显升高（P〈0．05），脐带长度和脐带过长发生率明显增高（P〈0．05），阴道胎吸助产率明显高于对照组（P〈0．05）。2组间其他指标无显著差异（P〉0．05）。结论脐带缠绕对分娩方式及分娩结局无不良影响，对脐带缠绕的产妇，可选择自然分娩，如出现胎儿窘迫再行剖宫产。

Objective To investigate the effects of cord entanglement on delivery methods and delivery outcome. Methods One hundred patients with cord entanglement in observation group and 100 patients with no cord entanglement in control group were surveilled with cardiotocography. The early deceleration（ ED ） , variable deceleration（VD） , late deceleration（LD） , fetal heart rate （FHR） , the rate of apnoea neonatorum, delivery methods and the length of abdominal stalk were compared. Results The incidence rate of VD and long cord, the length of abdominal stalk higher in contral group than these in observation group （ P 〈 0.05 ）, there was no significant deviation in other indexes between two groups （ P 〉 0.05 ）. Conclusion The cord entanglement weren＇t harmful effects to delivery methods and delivery outcoms. The lying-in woman can select spontaneous delivery or uterine-incision delivery if fetal distress.
