The effectiveness of three methods (Campbell and Wilkin, Warsof, Warsof et al for estimating fetal weight from measurements of the abdominal circumference (AC) and biparietal diameter (BPD) has been evaluated in 125 patients studied with dynamic image ultrasound. Investigations of the population as a whole indicated that the Campbell-Wilkin and Warsof methods systematically overestimated the weight (mean deviation: 5.3% and 1.6%, respectively), while the method of Warsof et al gave systematic underestimations (mean deviation: - 3.2%). The variability of the two Warsof methods was similar (SD: 8.8% and 8.4%) and significantly lower than that seen with the Campbell-Wilkin method (SD: 13.9%). When separate weight subclasses (500 gm to 4500 gm) were examined, the mean deviations and their variability were significantly lower with the two Warsof methods. The method of Warsof showed the most consistency among the weight subclasses. These results indicate that of these three methods, the best estimates of fetal weight are provided by the Warsof procedure.
在125例接受动态图像超声检查的患者中，评估了三种通过测量腹围（AC）和双顶径（BPD）来估计胎儿体重的方法（坎贝尔和威尔金法、沃索夫法、沃索夫等人的方法）。对总体人群的研究表明，坎贝尔 - 威尔金法和沃索夫法系统性地高估了体重（平均偏差分别为：5.3%和1.6%），而沃索夫等人的方法则系统性地低估了体重（平均偏差：-3.2%）。两种沃索夫法的变异性相似（标准差：8.8%和8.4%），且显著低于坎贝尔 - 威尔金法（标准差：13.9%）。当对不同体重亚组（500克至4500克）进行检查时，两种沃索夫法的平均偏差及其变异性显著更低。沃索夫法在各体重亚组中表现出最高的一致性。这些结果表明，在这三种方法中，沃索夫法对胎儿体重的估计最为准确。
