Accurate prenatal estimation of birth weight is useful in the management of labour and delivery. This study compared the accuracy of ultrasound, clinical and maternal estimates of fetal weight in 246 parous women with singleton, term pregnancies admitted for scheduled caesarean section. The sensitivity and specificity of predicting birth weight by ultrasound measures were 12.6% and 92.1%, by clinical palpation were 11.8% and 99.6% and by maternal estimate were 6.3% and 98.0% respectively. Clinicians' estimates of birth weight in term pregnancy were as accurate as routine ultrasound estimation in the week before delivery. Parous women's estimates of birth weight were more accurate than either clinical or ultrasound estimation.
准确的产前估计出生体重在分娩管理中很有用。本研究比较了 246 例单胎足月妊娠产妇的超声、临床和产妇估计胎儿体重的准确性，这些产妇因计划剖宫产而入院。超声测量预测出生体重的敏感性和特异性分别为 12.6%和 92.1%，临床触诊分别为 11.8%和 99.6%，而产妇估计分别为 6.3%和 98.0%。临床医生在分娩前一周对足月妊娠的出生体重估计与常规超声估计一样准确。经产妇对出生体重的估计比临床或超声估计更准确。
