摘　　要：目的:探讨超声测值口算法预测胎儿体重的可行性。材料和方法:对230例胎儿的头围、腹围、进行超声测量。参照出生时体重对比分析口算法和公式法预测胎儿体重的准确性。结果:口算法预测体重与出生体重符合184例,符合率占84%;公式法预测体重与出生体重符合200例,符合率占86.8%,两种方法误差分析无显著差异。结论:口算法与公式法比较预测胎儿体重的准确性无显著差异,但口算法方法简单,更具临床实用性。Purpose： A simplified estimation predicting the body weight of fetus based on ultrasonic measuring values was introduced in the current study. Materials and Methods： Ultrasonography was employed to measure the circumferences of head and abdomen of 230 fetus. Then the body weight of the fetus was estimated by a simplified algorism, and by a classical fetal-mass calculation formula. The estimated values was verified by the real birth weights of those neonates. Results： The estimation by the simplified method was consistent with the birth weight in 184 cases, with coincidence rate of 84% ; while classical formula obtained correct prediction in 200 cases （86.8%）. There was no statistically significant difference between the two methods. Conclusion： The simplified estimation based on ultrasonic measurements was feasible in predicting the body weight of a fetus.
