Ms. Rogers et al., ULTRASOUND FETAL WEIGHT ESTIMATION - PRECISION OR GUESS WORK, Australian and New Zealand Journal of Obstetrics and Gynaecology, 33(2), 1993, pp. 142-144
We compared the prediction of birth-weight based on factors shown by e
pidemiological studies to influence it with the performance of 2 clini
cal examples of ultrasonic fetal weight estimation reported in the lit
erature. The standardized absolute error of the 2 examples of ultrason
ic fetal weight estimation was similar to estimation by multiple regre
ssion of birth-weight on maternal age, parity, height and weight in 11
,516 Chinese mothers. This severely limits the clinical utility of the
estimation derived from these ultrasonic measurements.
