临床医生越来越依赖于超声检查预测巨大儿 ,来诊断分娩异常和决定分娩方式。产前预测巨大儿会导致剖宫产 (CS)率增加。本研究的目的是检验超声预测巨大儿不正确是否影响非巨大新生儿的 CS率。回顾复习 1991年 7月至 1996年 7月宾州和纽约两大学医院的产前超声记录。超声检查的 Clinicians are increasingly relying on ultrasound to predict macrosomia to diagnose abnormal childbirth and determine the mode of delivery. Prenatal prediction of giant children leads to an increase in the rate of cesarean section (CS). The purpose of this study was to examine whether ultrasound predicts macrosomia incorrectly affects the CS rate in non-giant newborns. Review the prenatal ultrasound records from July 1991 to July 1996 at two University hospitals in Pennsylvania and New York. Ultrasound examination
