目的:分析妊娠期糖尿病(gestational diabetes mellitus,GDM)孕妇中期超声测量对于胎儿生长情况评价的意义.方法:回顾性分析300例GDM孕妇从孕中期至分娩的超声检查临床资料,将巨大胎儿为观察组,正常胎儿为对照组,对胎儿生长各数值进行分析,评价其预测巨大儿的临床价值.结果:孕中期,观察组胎儿LL明显高于对照组胎儿,差异明显(P<0.05),具有统计学意义.新生儿期多元回归分析,对胎儿体重影响最大的是LL,其次为AC、FL,差异具有统计学意义(P<0.05);结论:超声能够较准确预测GDM孕妇的胎儿生长情况,值得临床推广应用.%Objective: To analyse ultrasound examination in the estimation of fetal growth in middle and late gestation between gestational diabetes mellitus. Method: Retrospective study was done on 300 GDM women. These neonatus were diveded into two groups: observation group ( macrossomias ) and control group ( normal ) . And analysed the data of ultrasound biometry measurements, including gestational age between 24 -28 weeks and before delivery, and the relation with neonatal weight. Result: The differences in LL between observation group and control group has statistical significance in gestational age between 24 - 28 weeks; In regression model of multiple regression analysis between birth weight and fetal ultrasound biometry measurements, LL had the most effect on birth weight, and AC, FL also had some effect. Conclusion: The ultrasound measurement is an accurate method in estimation of GDM fetal weight, and was well worth clinical popularizing and application.
