目的:通过对西宁地区336例巨大儿发生情况及围产儿的分析,合理选择巨大儿的分娩方式,提高对巨大儿阴道分娩的风险意识,努力减少母婴并发症,提高产科质量。方法:将我院1989年1月—2003年12月15年间分娩的体重≥4000g的巨大儿336例及全部产科资料纳入分析研究,与同期分娩的体重<4000g的正常体重新生儿336例作为对照,比较孕妇分娩并发症及围产儿有关情况。结果:巨大儿发生率有逐年上升的趋势,15年间发生率平均为1.5%,明显低于国内报道。巨大儿的分娩方式以剖宫产相对安全,剖宫产率为40.77%,阴道分娩中肩难产发生率明显高于对照组(P<0.01)。结论:西宁地区巨大儿发生率低于国内平原地区。巨大儿发生与孕母身高、过期妊娠及多产等因素有关。

Methods: A total of 336 obese children weighing> 4000 g and all the obstetric data were enrolled in our hospital from January 1989 to December 2003. The data were compared with 336 normal newborns weighing <4000 g in the same period , Compared with complications of pregnant women and perinatal delivery. Results: The incidence of macrosomia has been increasing year by year, with an average incidence of 15% in 15 years, which is obviously lower than that reported in China. Giant child delivery method to cesarean section is relatively safe, cesarean section rate was 40.77%, vaginal delivery in the incidence of shoulder dystocia was significantly higher than the control group (P <0.01). Conclusion: The incidence of huge children in Xining area is lower than that of the plain areas in China.
