Abstract
Objective: The purpose of this study was to find out some maternal and fetal factors affecting the accuracy of ultrasound in fetal weight estimation. Subject and method: This was a cross-sectional study performed on 104 mother-baby pairs at the Labour ward of Hai Phong Hospital of Obstetrics and Gyneacology. Fetal weight in-utero was estimated by ultrasound (less than 48 hours until delivery) and the actual birth weight was also recorded. Percentage of absolute error is the index used to evaluate the accuracy of ultrasound in fetal weight estimation, this index ≤ 10% was consindered accurate estimation, this index > 10% was consindered inaccurate estimation. Maternal and fetal factors were compared between these two groups. Result: 88.5% of cases were in accurate estimation group; 11.5% of cases were in inaccurate estimation group. Actual birth weight was significant different between two groups. Conclusion: The actual birth weight was the factor affecting the accuracy of the ultrasound in fetal weight estimation.
