The accuracy of estimated fetal wight determined by US scan in 70 fetuses with IUGR was analyzed using different formulas. The formula used in our Service showed the best correlation between estimated fetal weight and birth weight (R = 0.92), with estimation error not significant and +/- 8.3% variability. The foreign formulas showed significant estimation error and over 10% variability, therefore, in our population the use of the local formula is recommended.
使用不同公式分析了超声扫描测定的70例宫内生长受限胎儿的估计胎儿体重的准确性。我们科室使用的公式显示估计胎儿体重与出生体重之间的相关性最佳（R = 0.92），估计误差不显著，变异性为±8.3%。国外的公式显示出显著的估计误差和超过10%的变异性，因此，在我们的人群中，建议使用本地公式。
