Evaluation of Hadlock and Shepard formula in the estimation of fetus weight by sonography in 100 pregnant women

Background and

Since estimation of weight in study of intrautrine growth retardation (ÏÜGR) is important therefore this study was conducted due to importance of weight in premature fetus and macrosomia and estimation of weight in mothers with premature rupture of membranes (PRÔM). Ïn this propective study it was tried to find out the best and possible formula to estimale the fetal growth on the basis of parameters such as: BPD, FL and ÂÇ.

Hundred pregnant mothers, referred to Ësfahan educational hospital, who delivered about a week after sonography were selected. The fetal weight was estimated according to parameters of BPD, FL and ÂÇ by four formulas (Three hadlock and one shepart) then compared with the real birth weight to achive the results.

The results showed that Ë4 formula (one of the Had lock formulas using all the three parameters) is the best with standard deviation 28 g/kg. Çonclusions: Due to the development in sonography and determination of BPD, FL and ÂÇ, the estimation of fetal weight is possible with a minimal error.
