B超测量胎儿腹围预测胎儿体重的价值

Macrosomia Prediction Using Ultrasound Measurement of Fetal Abdo minal Circumference

目的研究B超测量胎儿腹围预测巨大胎儿的临床价值。方法选择184例宫高+腹围≥140cm的足月单胎孕妇,应用B超测量胎儿双顶径(BPD)、头围(HC)、腹围(AC)、股骨长度(FL);根据新生儿体重将孕妇分为巨大儿组及非巨大儿组,比较两组间差异;分析腹围与新生儿体重的关系。结果胎儿腹围与新生儿体重的相关性最好(r=0.84),当胎儿腹围≥35.0cm时,可以预测85.7%的巨大胎儿。结论超声测量胎儿腹围能准确预测巨大胎儿的体重。

Objective To evaluate the clinical of the fetal abdominal circumference measurement by ultrasound in prediction of macrosomia.Methods One hundred and eighty four pregnant women whose sum of the fundus height plus abdominal circumference was more than one hundred and forty were chosen,the biparietal diameter（BPD）,abdominal circumference（AC）,femoral length（FL）,head circumference（HC） of these fetuses were measured with ultrasound;According to the birth weight two groups were divided;macrosomic and nonmacrosomic groups,and the characterstics of two groups were compared;the relationship between abdominal circumference and birth weight was analyzed.Results The best predictor of birth weight was ultrasound measurement of fetal AC which had a correlation coefficient of 0.84.An AC of 35.0cm or more can predict 85.7% of macrosomic infants.Conclusions Fetal abdominal circumference measurement by ultrasound can predict macrosomia exactly.
