Comparative Study Between Clinical and Ultrasonography Estimation of Fetal Weight and Its Correlation with Actual Birth Weight
Abstract: Objective: Fetal weight estimation is critical for managing labour, delivery, and perinatal care. This study aimed to compare the accuracy of clinical estimation using standard palpation methods and Dare?s formula with ultrasonographic estimation employing biometric parameters (e. g. biparietal diameter, abdominal circumference, and femur length using Hadlock?s formula) in predicting actual birth weight. Methods: In a prospective observational study, 200 term pregnancies with singleton gestations were enrolled. Clinical fetal weight estimation was performed by trained clinicians using symphysio - fundal height and abdominal girth measurements, which were applied to Dare?s formula. Ultrasonographic estimation was conducted by a sonographer blinded to the clinical result using standard biometric measurements and Hadlock?s regression formula. The estimated fetal weights (EFWs) from both methods were then compared with the actual birth weight measured within 30 minutes of delivery. Accuracy was assessed by computing mean percentage error (MPE), mean absolute percentage error (MAPE), and the proportion of estimates within ?10% of actual birth weight. Results: Both estimation methods demonstrated significant correlation with actual birth weight (clinical: r = 0.71; ultrasound: r = 0.74; P
