[Ultrasonic measurement in the estimation of fetal weight].
OBJECTIVE
To study simple, reliable ultrasonic measurement in the estimation of fetal weight.


METHODS
(1) Study of the relationship between ultrasonic measurements of fetal biparietal diameter (BPD), cerebellar diameter (CD), femur length (FL) and abdominal circumference (AC) and neonatal birthweight in 300 cases. (2) Prospective study of the effect of abdominal circumference in estimation of fetal weight in 330 cases.


RESULTS
There was the significant correlation between fetal abdominal circumference and neonatal birth weight (r = 0.866 79). The prospective study in 330 cases showed the predictive value of fetal AC was 80.0%.


CONCLUSIONS
The ultrasonic measurement of fetal AC is a simple and valuable index in estimation of fetal weight.
