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 study the clinical value of B-ultrasound in the measurement of fetus abdominal mass. Methods A total of 184 pregnant women with full-term uterus and abdominal circumference≥140cm were enrolled in this study. BPD, HC, AC, and length of femur were measured by B-mode ultrasonography. Weight of pregnant women were divided into huge children group and non-huge children group, comparing the difference between the two groups; analysis of the relationship between abdominal circumference and newborn weight. Results The correlation between fetal abdominal circumference and newborn body weight was the best (r = 0.84). When the fetal abdominal circumference was more than 35.0 cm, 85.7% of the huge fetuses could be predicted. Conclusion Ultrasound measurement of fetal abdominal circumference can accurately predict the weight of a huge fetus.
