巨大儿196例临床分析

Clinical Analysis of 196 Fetal Macrosomias

目的 探讨巨大儿的产前诊断及正确的分娩方式。方法 通过对１９６ 例巨大儿的孕周、胎次、宫高腹围及胎儿双顶径进行回顾性分析，并随机抽取１９６ 例单胎正常新生儿体重做对比。结果 巨大儿的发生与胎次、孕周有关，通过测量宫高、腹围及胎儿双顶径有助于巨大儿的产前诊断。巨大儿的手术助产率及新生儿并发症均明显高于非巨大儿。结论 提高巨大儿的产前诊断率，选择正确的分娩方式很重要。

Objective To study the prenatal diagnosis and the right mode of delivery of macrosomia. Methods The gestational weeks, number of gravidity, height of uterus, abdominal circumference and biparietal diameter of 196 cases macrosomia were retrospectively analysed, and randomly selected 196 cases single infant normal meonate birth weight as the control group. Results The occurrence of macrosomia was associated with mumber of granidity and gestational weeks. Macrosomia was diagnosed according to height of uterus,abdominal circumference and biparietal diameter. The rate of transvaginal assisted delivery and newborn complications of macrosomia were significantly higher than those in the control group. Conclusion It is very important to increase the rate of prenatal diagnosis and to choose the right mode of delivery.
