Accuracy of fetal weight assessment by clinical method versus sonographic method

Abstract

Sonographic fetal weight estimation is an important component of antenatal care. Nonetheless, ultrasound was found to be more reliable method to establish fetal weight at term and more consistent in various period of gestations. Clinical method can be reliably used to screen large babies in centers where ultrasound has limited availability. The present study aimed to compare clinical and sonographic methods for assessment of fetal weight regarding sensitivity, specificity and accuracy. The study recruited 100 women scheduled for delivery from ante-natal care clinic with 38 weeks or more of gestation. Fetal weight was assed clinically and by ultrasound. Both techniques were compared and analyzed. In the current study, comparison between clinical and ultrasound fetal weight estimates and the actual birth weight
