目的:采用多个参数指标预测胎儿体重,选择相应分娩方式。方法:孕38周后测胎儿双顶径、股骨径、头围及腹围,根据相应标准分组,预测胎儿体重。结果:双顶径+股骨径<17 cm,腹围<35 cm,一般胎儿体重<3 500 g;头围>35 cm,腹围>36 cm,高体重儿可能性明显增加。如腹围>37 cm,高度提示巨大胎儿。结论:采用多参数指标能较准确预测胎儿体重,筛选高体重儿(>3 750 g),选择合适的分娩方式可避免产伤,降低难产率。
OBJECTIVE: To predict fetal weight by multiple parameters and to choose the mode of delivery. Methods: Fetal biparietal diameter, femoral diameter, head circumference and abdominal circumference were measured after 38 weeks’ gestation. The fetal weight was predicted according to the corresponding standard. Results: Bipap diameter + femoral diameter <17 cm, abdominal circumference <35 cm, general fetal weight <3 500 g; head circumference> 35 cm, abdominal circumference> 36 cm, the possibility of high birth weight increased significantly. Such as abdominal circumference> 37 cm, highly suggestive of huge fetus. Conclusion: The multi-parameter index can predict fetal weight more accurately, select high-birth-weight infants (> 3 750 g), and choose the mode of delivery to avoid birth injury and reduce the rate of dystocia.
