Abstract

OBJECTIVE

The purpose of this study was to evaluate the prediction of fetal macrosomia based on ultrasound estimates of fetal weight and amniotic fluid volume combined with clinical risk factors.

METHODS

A retrospective cohort study of women undergoing indicated obstetric ultrasound examinations within 7 days of delivery was conducted.

RESULTS

A total of 3115 women gave birth within 7 days of ultrasound examinations that included an estimated fetal weight (EFW) and an amniotic fluid index (AFI). Clinical risk factors were associated with an 8% positive predictive value for a birth weight of 4000 g or higher. Adding an ultrasound EFW of 4000 g or higher increased the positive predictive value to 62%. Adding an AFI of 20 cm or higher to the clinical risk factors and the ultrasound EFW further increased the positive predictive value to 71%.

CONCLUSIONS

An ultrasound EFW of 4000 g or higher within 1 week of delivery combined with clinical risk factors and an increased AFI is associated with macrosomia at birth in 71% of cases.

摘要

目的

本研究旨在评估基于胎儿体重超声估计值、羊水量与临床危险因素相结合对巨大儿的预测情况。

方法

对在分娩前7天内接受产科超声检查的女性进行一项回顾性队列研究。

结果

共有3115名女性在超声检查后7天内分娩，超声检查包括估计胎儿体重（EFW）和羊水指数（AFI）。临床危险因素对出生体重4000克及以上的阳性预测值为8%。增加超声估计胎儿体重4000克及以上可将阳性预测值提高到62%。在临床危险因素和超声估计胎儿体重基础上增加羊水指数20厘米及以上可进一步将阳性预测值提高到71%。
