Abstract

Introduction:Accurate estimation of fetal weight is important in the management of delivery.Ultrasonography is widely used for fetal weight estimation because of cost-effectiveness and well defined measurement procedure.Early methods to predict birth weight with an ultrasound will help the clinicians to make decisions on the route of delivery.

Method:This was a cross sectional study conducted at Lumbini Medical College and Teaching Hospital, Palpa in the Department of Radiodiagnosis for a duration of nine months from February 2024 to October 2024. The study was approved by the Institutional Review Committee of the institute (IRC-LMC-05/M-24). The study population included singleton pregnancy at term (at/after 37 weeks) meeting inclusion criteria. A total of 180 pregnant women participated in study.

Result:The mean actual birth weight (ABW) was 3070.57 gram ± 301.13.The estimated mean fetal birth weight (EFW) by ultrasound was 3346.62±204.29 grams using Hadlock 1 and 3308.89±204.69 grams using Hadlock 2. There was no significant difference between the mean fetal weight estimated by ultrasound scan using Hadlock formula and mean actual birth weight (p-value = <0.05). There was a positive correlation between ultrasound estimated fetal weight and actual birth weight (r=0.34,p<0.05 for Hadlock 1 and r=0.36,p<0.05 for Hadlock 2).

Conclusion:Ultrasound is reliable method for estimating fetal birth weight through Hadlock formula and it has strong correlations with actual birth weight, making it the preferred method for estimating fetal weight and planning delivery.
