“…Malik R et al also found, in a study comparing 3 clinical and 3 ultrasonographic equation for predicting fetal birth weight, that in estimating weight <2500 gm and >3500 gram there was a role of ultrasound as additional tool. 12 Sensitivity and Specificity of ultrasonography formulae were more in <2500g and >3500g as compared to clinical method.…”

Background: This is a prospective study was conducted at Obstetrics and Gynecology department, tertiary care Hospital, to compare the accuracy of clinical and ultrasonographic estimation of fetal weight at term with actual birth weight.Methods: The present study is a prospective comparative study of fetal weight estimation in Antenatal women with term gestation (37week to 42week of gestation) singleton pregnancy with vertex presentation, who had gestational age confirmed by dates and ultrasound scanning of< 22weeks admitted in tertiary care center from March 2016 to November 2016. Patients with Polyhydramnios, oligohydramnios, Antepartum hemorrhage, Congenital anomalies of fetus, Obese (Body mass index >30 kilogram/meter2) are excluded from the study. Estimation of fetal weight is done by clinical method and ultrasonography. Birth weight after delivery was recorded in grams by electronic weighing machine and tabulated.Results: Clinical as well as ultrasonography estimates observed to be strongly correlate with actual birth weight. Both the methods had more sensitivity in birth weight range 2500-4000gm than <2500g and >4000g. The overall mean absolute percentage error of the clinical method (7.2±7.7) was smaller than that of the sonographic method (16.2±11.1). In low birth-weight (<2,500g) group, mean absolute percentage error was 9.0±11.3 with USG and same with clinical was 11.7±9.0. No statistically significant difference was observed.Conclusions: The present study concludes that clinical estimation of birth-weight is as accurate as routine ultrasonographic estimation.Clinical palpation should be considered as diagnostic tool for FWE and is equally reliable even when done by trained medical person. It is cheap and easy to teach. The need is to practically apply this method in obstetrics and guide the management decisions.

“…Malik et al 21 in India found that Dare’s formula overestimated birth weight in 84% of the participants in their study. This was higher than was found in the present study, where Dare’s formula overestimated birth weight in 33.8% of babies with normal weight.…”

Background A reliable prediction of foetal birth weight aids in decision regarding time and mode of delivery. Aim This study aimed to determine the accuracy of the product of symphysio-fundal height and abdominal girth in predicting birth weight among pregnant women in Keffi, Nigeria. Setting The study involved pregnant women presenting for delivery at the Federal Medical Centre, Keffi, Nigeria from July to October 2017. Methods One hundred and fifty-three pregnant women at term with singleton foetuses were recruited by systematic random sampling. An interviewer-administered questionnaire was used to obtain their socio-demographic data, past medical and obstetric history. Symphysio-fundal height and abdominal girth measurements were used to calculate the estimated foetal weight. This was compared with the actual birth weight. Absolute percentage error was used to determine the overall predictive error of Dare’s formula. Data were analysed using SPSS version 20.0. Statistical significance was set at p < 0.05 and 95% confidence level. Results The mean age of the participants was 29.65 ± 5.15 years. The mean gestational age was 39.5 ± 1.2 weeks. There was a significant correlation ( r = 0.52, p < 0.001) between the estimated foetal weight and the actual birth weight. Ninety (66.2%) of the babies within normal weight and six (85.7%) of macrosomic babies were correctly predicted. None of the low birth weight babies was correctly predicted by the formula. Conclusion Dare’s formula accurately predicted normal weight and macrosomic babies, but less accurately predicted low birth weight babies.

Introduction: Assessment of fetal weight is a vital factor in antenatal care, not only in the management of labor and delivery but also in identifying fetal weight disorders. Objective: This study compares the accuracy of clinical methods and ultrasonography in Estimating Fetal Weight (EFW) with Actual Birth Weight (ABW) in term pregnant women. Materials and Methods: This diagnostic test evaluation study was performed on 247 single-term pregnant women admitted to an educational, therapeutic hospital in Rasht City, Iran. In this study, abdominal palpation, Johnson’s formula, Insler’s formula, and ultrasonography were used to estimate fetal weight. One-sample t-test, the Chi-square, and the Bland-Altman plot were used to compare the diagnostic value of fetal weight estimation methods. The accuracy of tests was estimated based on sensitivity and specificity in fetal weight groups (below 2500 g, 2500- 4000 g, and above 4000 g) by the Bland-Altman plot. Results: The participating pregnant women had a Mean±SD age of 28.86±4.24 years, body mass index of 32.98±6.0 kg/m2, and gestational age of 39±1.04 wk. Their Mean±SD actual birth weight was 3343.352±432.799 gr, Also, the Mean±SD birth weight found by abdominal palpation was 3371.053±345.561 gr, Mean±SD birth weight by Johnson’s formula 3041.206 ±411 gr, by Insler’s formula 3556.316±531.567 gr, and by ultrasonography 3294.28±380.09 gr, Based on the one-sample t-test, the abdominal palpation had the lowest (P=0.261), and the Insler’s formula (P=0.001) had the highest difference with the actual birth weight. Regarding the fetal weight groups, Insler’s formula (96.33%) was highly accurate in Low Birth Weight (LBW), but abdominal palpation (91.09%) was more accurate in normal weight and macrosomia (94.72%) groups. There was a significant difference between clinical methods with ABW (P=0.026). Conclusion: Clinical methods are accessible, affordable, and available and can estimate fetal weight in developing countries, especially in our country.
