巨大儿相关因素及妊娠结局分析

目的 探讨巨大儿发生的相关因素、分娩方式及并发症,提高产前诊断率,选择恰当的分娩方式.方法 回顾性分析我院2011年1月至2012年12月分娩的267例巨大儿的情况,并随机选择同期分娩的267例体重2 500～3 999 g的新生儿作为对照组进行比较.结果 研究组孕妇身高、体重、产次、孕龄、宫高、腹围及胎儿双顶径、股骨长、腹围明显高于对照组（P＜0.01）;研究组剖宫产率明显增高,剖宫产组分娩并发症明显低于阴道分娩组.结论 巨大儿增加母婴并发症,应正确产前诊断,巨大儿分娩方式以剖宫产相对安全.

Analysis of Related Factors of Fetal Macrosomia and Pregnancy Outcome

Objective To explore the related factors of macrosomias, mode of delivery and complications, and improve prenatal diagnosis so as to choose the appropriate mode of delivery. Methods 267 cases of macrosomias in our hospital from January 2011 to December 2012 were analyzed retrospectively, and 267 cases of newborns weighing 2 500 - 3 999 g who were born at the same time were randomly chosen as control group for comparison. Results The results showed that the height, weight, parity, gestational age, uterine height, abdominal circumference and fetal biparietal diameter, femur length, abdominal circumference of the pregnant women in the study group were significantly higher （P 〈0.01）; the rate of cesarean section in the study group was significantly higher, the incidence of the complications was significantly lower in the split cesarean delivery group than that in the vaginal delivery group. Conclusions Macrosomias increase maternal complications, so the prenatal diagnosis should be properly made; and cesarean delivery mode is safer for macrosomias.
