153例巨大胎儿临床分析

Clinical Analysis of 153 Macrosomia Cases

目的 :为了寻找预测巨大儿的相关因素 .方法 :对 15 3例巨大儿 (出生体重≥ 4 0 0 0 g)的临床资料进行分析 ,选择周期 (2日内 )分娩的 15 3例正常足月胎儿 (出生体重 <4 0 0 0 g)作对照 ;结果 :观察组孕妇年龄、分娩孕周、孕产次与对照组比较无统计学差异 ,而身高、分娩前体重指数 (BMI)、腹围、宫高、并发症均高于对照组 ,并有统计学差异 .巨大儿男婴多于女婴 .巨大儿组分娩方式以剖宫产为主 ,剖宫率为 70 6 % ,高于对照组 39 9% .结论 :产妇体重、身高、宫高、腹围、孕产次对产前诊断巨大儿有参考价值 。

Objective: to investigate the relevant factors for macrosomia diagnosis by retrospective analysis of 153 macrosomia cases. Methods: medical records of all 153 macrosomia cases (birthweight≥4?000?g) delivered in our hospital during January 1998 to December 2?000 were reviewed and 153 normal newborn (birthweight <4?000?g) delivered in the same time (within 2 days) were selected as controls. Maternal height and body weight, gestational week, delivery pattern, pregnancy complications and conditions of newborns were compared. Results: for macrosomia, maternal age, height , weight gain during pregnancy, number of gravidity and PAPA were significantly higher than those in controls. Among macrosomia infants, males were more than females. The rate of cesarean section delivery was 70.6% in macrosomia cases vs. 39 9% in control groups (P<0 01). Conclusions: maternal weight , height and abdominal circle are predictive factors for macrosomia diagnosis. Ultrasound may contribute to prenatal diagnosis of macrosomia. Cesarean section is a relatively safer choice for macrosomia delivery.
