A new method for estimating the fetal weight is described, based on symphysis-fundus height and gestational age. The relationship between ultrasound-estimated fetal weight, gestational age, and symphysis-fundus height was determined using multiple regression analysis in a low-risk group. The accuracy of the regression formula was tested retrospectively on two target populations: a second low-risk group and a higher risk group undergoing elective delivery. The formula overestimated weight by 3.6%. The standard deviation of the random errors for the first group was 10.3% whereas in the second it was 11.9%. Fetal weight estimation using symphysis-fundus height and gestational age can be performed with an accuracy comparable to that of ultrasound.
本文描述了一种基于耻骨联合-宫底高度和孕周估算胎儿体重的新方法。在低风险组中，通过多元回归分析确定了超声估算胎儿体重、孕周和耻骨联合-宫底高度之间的关系。该回归公式的准确性在两个目标人群中进行了回顾性测试：第二个低风险组和接受择期分娩的高风险组。该公式高估体重3.6%。第一组随机误差的标准差为10.3%，而第二组为11.9%。使用耻骨联合-宫底高度和孕周估算胎儿体重的准确性与超声相当。
