Comparison of various methods for estimating fetal weight

Abstract

Comparison of various methods for estimation
of foetal weight. OBJECTIVE Accurate
foetal weight estimation is important
for predicting neonatal morbidity and
mortality and for planning obstetric management.
This study aimed to investigate
the limits of foetal weight estimation by
conventional biometric parameters and
ultrasonogram and comparism of these
methods.METHODSA prospective study
involving 396 term pregnant
womensingletonadequate liquorcephalic
presentation, where estimated foetal
weight were calculated using three methods
of which two were involving the biometric
parameters and one was by ultrasonogram
estimation of foetal
weight.RESULTSA total of 396 of the
605 women who presented to labor ward
with painsterm gestation 186 (47) had
estimated foetal weight calculated by
DARE'S formula ( SFW AG) - 200
grams ,150 (38) women had estimated
foetal weight calculated by ultrasonograms
-200 grams and 59 (15)
women had estimated foetal weight calculated
by JOHNSON formula - 200 grams of
post natal foetal weight.CONCLUSIONThis
study shows the estimated foetal weight
using DARE'S formula seems to be more
reliable when compared to other methods.
