持续性枕后位对分娩结局的影响

目的探讨持续性枕后位对分娩结局的影响。方法选择2009年1月～2010年12月住院分娩的152例产妇的资料进行回顾性分析,持续性枕后位76例作为观察组,枕前位76例作为对照组,分析持续性枕后位对分娩方式和围产儿的影响。结果观察组自然分娩率低于枕前位组,产钳助产、剖宫产、软产道裂伤、产后出血率明显高于对照组,枕后位组胎儿窘迫、新生儿窒息率明显高于对照组,两组比较差异均有统计学意义(P<0.05)。结论持续性枕后位是头位难产的主要原因之一,手术产率明显增加,产妇及围产儿并发症增加,因此应对持续性枕后位做出早期诊断和处理,减少产妇及新生儿并发症的发生。

Objective To investigate the effect of occiput posterior position on pregnant outcome.Methods The data on 152 primipara were retrospectivly analyzed.76 primipara with fetus in an occiput posterior position formed observation group and 76 primipara with fetus in an occiput anterior position formed control group.The mode of delivery,puerpera and neonatal complications were compared between the two groups.Results The incidence rates of forceps delivery,cesarean section,perineal tear,postpartum haemorrhage were significantly higher and the spontaneous delivery rate was significantly lower in the observe group as compared with those in the control group（P0.05）.The incidence rates of fetal distress and birth asphyxia in observe group were significantly higher than that in the control group（P0.05）.Conclusion Persistent occiput posterior position is main reason of cephalic dystocia,which can lead to higher incidence of complicationsin in puerpera and fetus.Better prognosis may be achieved by early treatment and selecting the best mode of delivery.
