Assessment of ultrasound fetal weight equations in Egyptian pregnant women

ABSTRACT

Estimation of fetal weight [FT] by ultrasound [US], is one of the major outputs of diagnostic ultrasonography. Many equations have been generated to achieve this objective. The aim of this work was to assess the reliability of these equations, and determine which one will be more suitable to be applied in Egyptian population. Two hundred full term, normal Egyptian pregnants were selected. US examination was done in the latent phase of labor. After the routine scan, the biparietal diameter [BPD], abdominal circumference [AC] and femur length [FL] were measured. The estimated FW was calculated according to Shepard, Campbell, and Hadlock's equations. The differences between the actual and estimated FW by the 3 equations were statistically nonsignificant. These results indicated that either of the three equations can be used in estimating FW in Egyptian population
