“…In addition, it is characterized by being a standard clinical method as an alternative to ultrasound (USG) which is expensive and not always easy to access, especially in countries with limited financial resources for health. 4 Knowledge of the weight of the fetus in utero is important for the obstetrician to decide whether to deliver or not to deliver the fetus and also to decide on the mode of delivery. Estimation of fetal weight is being done clinically, which has been criticized as less accurate because of observer variations.…”

Background: Fetal growth assessment is an important part of antenatal care. Accurate estimation of fetal weight is one of the important aspects in management of labour. Estimation of birth weight by Johnson’s formula based on symphysiofundal height has advantage of speed, economy and general applicability. Obstetric ultrasound can predict fetal weight with a great degree of precision. Methods: The prospective study was conducted at the Department of Obstetrics and Gyenecology, Yenepoya Medical College and Hospital, Mangalore on 100 pregnant women at or near term. Detailed history was taken, general, obstetric and systemic examination was done. Pelvic examination also done. Estimated fetal weight calculated using Johnson’s formula clinically and ultrasound was done to calculate estimated fetal weight using Handlock’s formula and correlated the birth weight calculated by two methods with its actual birth weight. Then the statistical analysis done to estimate the accuracy of two methods in estimated fetal weight. Results: In this study, out of 100 pregnant women, mean actual birth weight was 3041.6gms. Actual birth weight divided into 3 groups 14% birth weight <2.5kg, 73% had 2.5-3.5kg and 13% had >3.5kg. Accuracy of both methods evaluated, ultrasonographic measurement more accurate than clinical estimation but the error with Johnson’s formula was with low birth babies. Conclusions: Estimated fetal weight using Ultrasonographic Handlock’s formula was more accurate than Johnson’s formula. However, the results of Johnson’s formula were comparable to Handlock’s.

Background: Fetal weight estimation by ultrasound is an important factor in obstetrics; it is directly related to the gestational age which helps to plan the mode of delivery and labor management. Objective: to compare between fetal thigh circumference (TC) and abdominal subcutaneous tissue thickness (SCT) in estimating birthweight in term pregnant women. Patients and Methods: This prospective cohort study was conducted at outpatient clinic or emergency room, Obstetrics and Gynecology Department, Faculty of Medicine, Ain Shams University Maternity Hospitals from March 2022 until May 2023. During this study, 100 term pregnant females with gestational age 37 -40 weeks attended El Demerdash Maternity Hospital and scheduled for delivery either at outpatient clinic or emergency room were enrolled, after consenting each of them. Basic fetal biometry was performed by an expert and professional medical personnel to ensure the accuracy of examination results. Fetal abdominal subcutaneous thickness and fetal thigh circumference were measured for assessment of gestational age and correlated with actual fetal body weight. In the current study, three formulas; Hadlock, Vintzileos' and SCT formula were correlated with actual fetal body weight after birth. Results: The present study revealed that TC formula is closer to the actual birth weight, followed by Hadlock formula, while the SCT formula is the furthest from it. Conclusion: To increase the accuracy of birth estimations, regular ultrasound examinations should include fetal thigh circumference measurement.

“…As a result, a precise assessment of birth weight might aid in labour management, perhaps averting some of these difficulties. In utero foetal growth and weight have been estimated using clinical investigations and ultrasound approaches (6)(7)(8)(9) .…”

Background: Accurate foetal birth weight estimate is crucial for detecting growth limitation, preterm, and situations where clinical decisions affecting labour induction or delivery mode need to be made. This research study was conducted to determine the accuracy of predicting prenatal weight using foetal thigh circumference (TC). Patients and methods: Between November 2018 and September 2019, we performed a cross-sectional study of pregnant women. We included single intrauterine pregnant women with no complications, and who delivered within 48 hours after examination, with gestational ages ranging from 38 to 41 weeks. Within 48 hours following birth, the true foetal weight was estimated. Results: We included 123 pregnant women, with a mean gestational age of 38.78 (SD 0.85) weeks and a mean age of 26.68 (SD 5.24) years. Of them, 21.1% were nulliparous. We found an ultrasound parameter-to-actual-weight association that was statistically significant in favour. The greatest association between actual foetal weight and TC (r =0.685; p<0.001). Simple linear regression showed that TC is a predictor of estimated fetal weight (B =153.5, p< 0.001). Between estimated foetal weight and actual weight, as well as between estimated and real TC, we found no discernible difference (p values 0.398 and 0.06, respectively). Conclusion:When used in conjunction with other fetal measures, the foetal thigh circumference may aid in the precise computation of fetal birth weight. To increase the accuracy of birth estimations, regular ultrasound examinations should include fetal thigh circumference measurement.
