目前,国内多通过宫高、腹围的外测值,经多元回归方程计算来估计胎儿体重,因受孕妇腹壁脂肪厚薄、单水多少、胎头高低等诸因素的影响,准确率只在50～70％左右。为此,我院应用B超测量胎头双顶径、腹部直径、股骨长度之值的方法,来预测胎儿的体重500例,将其结果报道如下。 At present, the majority of domestic high through the uterine circumference, abdominal measurements measured by multivariate regression equation to estimate the weight of the fetus, pregnant women due to abdominal fat thickness, water number, fetal head height and other factors, the accuracy rate of only 50 ~ 70% or so. To this end, our hospital using B-measurement of fetal head biparietal diameter, abdominal diameter, the length of the femur method to predict the fetus’s body weight 500 cases, the results reported below.
