138例巨大儿的产前诊断

目的通过对138例巨大儿的临床分析，寻找诊断巨大儿的因素。方法入选观察组138例（出生体重〉4000g），选择同时期出生的138例适龄足月儿为对照，比较两组孕妇年龄、分娩孕周、身高、体重增长、双顶径、股骨长、腹围、新生儿性别、分娩方式和合并症有关情况。结果巨大儿组在孕期体重增长、双顶径、股骨长、腹围、宫高＋腹围、性别、分娩方式等均高于对照组，差异有显著性意义。结论孕产妇应注意孕期体重增长，分娩前综合各方因素充分评估胎儿大小来减少因忽略巨大儿的诊断而带来的产时损伤。

Maternal age, gestational weeks, maternal body weightgain, BPD, FL, AC, neonatal gender, delivery Pattern and pregnancy complications were compared. Results： In macrosomia, maternal weightgain during pregnancy, BPD, FL, AC, neonatal gender and delivery pattern were significantly higher than those in controls. （ P 〈 0. 05 ） Conclusions ： Parturient should be attention maternal weightgain, it evaluated thoroughly on account of various factors the fetal body weightgain to reduced delivery injury in prior to brith.
