孕期肥胖对分娩过程及结局的影响

Impact of pregnancy obesity on delivery process and outcomes

目的:探讨孕妇孕期肥胖对分娩方式及分娩过程所产生的影响,以尽量避免不良结果的发生。方法:选取2004年1月～2006年1月在我院门诊建卡产检至住院分娩的足月单胎初产妇1803例,其中符合孕前肥胖(体重指数BMI≥25kg/m2)及孕期肥胖(孕期体重增长≥15kg)的孕妇110例(6.10%)作为观察组,随机从其余孕妇中抽取280例作为对照组。观察两组肥胖孕妇的分娩方式、产程、宫口扩张速度及产后出血、新生儿窒息、巨大儿发生情况。结果:肥胖孕妇的产程异常率、宫口扩张速度、产后出血、巨大儿、新生儿窒息率与对照组比较,有显著性差异或非常显著性差异(P<0.05或P<0.01)。结论:孕期肥胖对产妇和新生儿均产生不利影响,增加了难产发生率、产程延长、产后出血及新生儿窒息的发生率。

Objective：To investigate the impact of pregnancy obesity on delivery process and outcomes and to avoid the occurrence of adverse results.Methods：1 803 unipara who were full-months,ingle fetus and had the cards from January 2004 to January 2006 in the clinic of our hospital were selected.Among of them,110 cases were BMI ≥25 kg/m2 and pregnancy obesity（maternal weight gain ≥15 kg）,as the observation group,the other 280 cases were as the control group.Mode of delivery,labor,cervical dilation rate,and postpartum hemorrhage,neonatal asphyxia,significant incidence of child were observed between two groups.Results：Abnormal rate of labor,cervical dilation rate,postpartum hemorrhage,great children,neonatal asphyxia of obese pregnant women compared with those of the control group,there were significant differences（P0.05 or P0.01）.Conclusion：Pregnancy obesity can produce adverse effect for maternal and neonatal,increase the incidence of dystocia,prolonged labor,postpartum hemorrhage and neonatal asphyxia.
