A comparison between ultrasound and clinical methods for predicting fetal weight

Fetal weight prediction by different methods were compared. Those methods were ultrasound fetal weight estimations using Campbell, Warsof and Hadlock equations, and clinical subjective estimation by experienced obstetricians, as well as clinical objective studies (Zayed's equation). We evaluated 523 Jordanian (Arabic) patients in labour. Our results shows that ultrasound equation provides the highest accuracy in predicting fetal weight. In this study Hadlock's equation was more precise than the other equations. There is still a place for clinical fetal weight estimation, especially if objection methods are used.
