Research on Methods for Predicting Fetal Weight Using Ultrasonography

Objective To explore the related factors and the clinical application value of each factor for prenatal prediction of fetal birth weight. Methods The estimated fetal weight according to relevant formula through the measurement of pregnant women's uterus height and abdomen circumference were calculated, and the fetal weight through the ultrasonography measurement of their biparietal diameter, head circumference, abdominal circumfercene and femur length were predicted. Then the estimated fetal weight with the actual fetal weight after delivery was compared and analyzed. Results The application of ultrasound to measure a number of factors for estimating fetal weight was significantly superior to traditional forecasting methods and the single factor forecast, P 0.01. Conclusions The ultrasonic measurement of biparietal diameter, abdominal circumfercene and femur length is a accurate, simple and valuable parameter in estimation of fetal weight. Multi-parameter formula is much better than mono-parameter formula in estimating fetal weight.
