Abstract

In this study the fetal weight was estimated by ultrasound measurements of the biparietal (BPD) and abdominal diameters (AD) in 154 consecutive twin pregnancies. In 80 twins an attempt to estimate fetal weight was made 0-4 days before delivery (26% of all twins examined). In 84% (67 infants) it was possible to estimate the fetal weight using the formula (0.0108 X AD1.72 X BPD0.99). 60% of the birth weights deviated less than 10% from the estimated fetal weight and 83% deviated less than 15%. The prediction error was nearly constant, expressed as percent of actual weight in the different weight groups (8.5-9.8%). In 19 LGA infants, 69% of the birth weights deviated less than 10% from the estimated fetal weight and 70% deviated less than 15%.

摘要

在本研究中，通过超声测量154例连续双胎妊娠的双顶径（BPD）和腹径（AD）来估计胎儿体重。在80例双胎中，于分娩前0 - 4天尝试估计胎儿体重（占所有检查双胎的26%）。84%（67例婴儿）能够使用公式（0.0108×AD1.72×BPD0.99）估计胎儿体重。60%的出生体重与估计胎儿体重的偏差小于10%，83%的偏差小于15%。预测误差几乎恒定，以不同体重组实际体重的百分比表示（8.5 - 9.8%）。在19例大于胎龄儿中，69%的出生体重与估计胎儿体重的偏差小于10%，70%的偏差小于15%。
