巨大儿2344例调查研究

Investigation of 2344 cases of macrosomia

目的 探讨近年来巨大儿的发生率变化及与巨大儿发生有关的因素。方法 回顾性分析 1989～1998年间在我院分娩的婴儿中巨大儿的发生率 ,分析 10年中巨大儿发生率变化规律 ,并对其相关因素进行分析。结果 10年间在我院分娩的婴儿总数为 396 31例 ,其中巨大儿 2 344例 ,发生率为 5 .91%。孕妇身高在16 5～ 170cm之间 ,孕期体重增加 2 5kg以上 ,孕周达 40周以上 ,胎儿双顶径≥ 96mm。以上诸因素与巨大儿发生密切相关。结论 巨大儿为一组特殊的异常胎儿 ,其剖宫产率高达 6 3 .83 % ,与同期非巨大儿人群的剖宫产率 38.5 0 %相比 ,差异有显著性 ,P <0 .0 0 5。因此 ,临床工作应重在对巨大儿的积极预防 ,明确产前诊断及正确处理 。

Objective To study the changing incidence of macrosomia in recent years and the relevant factors of the occurrence of macrosomia. Methods To estimate the incidence of the macrosomia during 1989 1998 in our hospital and analysis the relevant factors of the occurrence of macrosomia retrospectively. Results There were 39631 deliveries during 1989 1998 in our hospital, the incidence of macrosomia was 5.91%.The following factors had a close correlation with the occurrence of maorosomia: (1) The pregnant woman's height was 165 cm to 170 cm. (2) The weight gain in pregnancy was over 25 kilograms. (3) The gestational period was over forty weeks. (4) Fetal biparietal diameter was 96 mm or more. Conclusion Macrosomia is a special group of abnormal fetuses. Compared with the normal group (38.5%) the cesarean section rate of the macrosomia group (63.83%) is significantly increased at the same period. ( P <0.005). In our clinical practice, we should pay more attention active prevention to active prevention antenatal diagnosis, correct management, and reduce the occurrence of macrosomia
