Comparative Estimation of Fetal Weight in both Normal and High Risk Term Pregnancy by Clinical and Ultrasound Examination
Journal Title: Indian Journal of Obstetrics and Gynecology - Year 2017, Vol 5, Issue 4
Abstract
Aim: To make a comparative estimation of fetal weight in both normal and high risk term pregnancy by clinical and ultrasound examination. Materials and Methods: This is a prospective hoapital based study on 100 antenatal women attending Department of Obstetrics and Gynaecology admitted for planned delivery for various reasons either by elective caesarean section or by induction of labour. Results: Using Johnson’s method 36% were within 5%, 67% were within 10% of the predicted fetal weight and in 67% of cases the birth weight was ±200 gms of the predicted weight. In 92% of cases the birth weight was within ± 500 gms of actual birth weight as an acceptable limit to predict the fetal weight clinically. Johnson’s method was least accurate when the birth weight is below 2500 gms and increased accuracy was found in the weight range of 2500 gms and above. Using Insler’s (AG X SFH) method 49% of the cases birth weight was within 5% of the of the predicted weight. By using AG X SFH, birth weight was over estimated than under estimated. 71% cases were within ± 200 gms and 97% were within ± 500 gms of the predicted weight. Insler’s method (AG X SFH) was found to be more accurate in weight range 2.501 to 3.5 kg. By Hadlock’s formula 55% were within 5% of predicted fetal weight. 88% were within 15% of predicted fetal weight. 76% gave error of ± 200 gms. It is most accurate between weight range of 2.5 to 3.5 kg weight group. While comparing all the three methods over estimation was almost equal with Ultrasonography and Insler’s (AG X SFH) method. Conclusion: Insler’s (AG X SFH) method which is simple, easy and less cumbersome method to predict the fetal weight in a developing country like India where sophisticated gadgets are not easily available.
