超声腹围测量对巨大胎儿预测的临床价值

Ultrasonic measurement of abdomen circumference in diagnosis of fetal macrosomia

目的:探讨超声腹围测量对预测巨大儿的临床价值。方法:超声测量389例胎儿腹围,分析其与新生儿体重相关关系,并评估胎儿腹围在巨大儿预测方面的临床价值。结果:胎儿腹围与巨大胎儿体重存在高度正相关,相关系数r值为0.801 92;当腹围>350mm时,巨大儿的发生率明显升高;当腹围在360～370mm时其预测巨大儿的特异度达91.8%。结论:胎儿腹围与巨大儿的发生密切相关,腹围>360mm可作为预测巨大儿的单一指标。

Objective： To explore the clinical application of ultrasonic measurement of abdomen circumference in diagnosis of fetal macrosomia.Methods：The abdomen circumferences of 389 fetuses were examined with ultrasound,and its correlation with neonatal weight was analyzed to evaluate the clinical applications of ultrasounic measurement of abdomen circumferenc.Results：Abdomen circumference had significant correlation with weight,which had a correlation coefficient of 0.80192.The incidence rate of macrosomia was obviously increased when abdomen circumference were greater than 350 mm.The specificity of macrosomia prediction were 90.8% when abdomen circumference were between 360 mm and 370 mm.Conclusions：The abdomen circumference has a close correlation with incidence of macrosomia.When abdomen circumference were greater than 360 mm,it can be used as a single index for macrosomia prediction.
