Estimate Fetal Weight

Introduction: the aim of this trial was to estimate fetal weight by clinical and ultrasound methods and to compare with the weight at birth in full-term newborns. Methods: This is an epidemiological, observational, cross-sectional study of a cohort of healthy full-term newborns. The sample size was 102 neonates born at the Pablo Arturo Suarez Hospital, in Quito, Ecuador, from November 2019 to January 2020. Results: In full-term neonates, the estimate on ultrasound was 80.00%, while in the clinical assessment was 72.29%. The profile of newborn analyzed is man, mestizo, Ecuadorian, born in the highlands region, with a mean gestational age of 38.67 weeks and a mean birth weight of 3,023 grams, in whom it estimated the fetal weight through ultrasound and clinical assessment. The estimation of the absolute error in both methods analyzed was 2.43% to ultrasound and -4.65% to clinical assessment, and both showed moderate concordance, 78.2% to ultrasound, and 85.6% to clinical assessment. Multivariate analysis showed the neonates with modified weight by ultrasound are 13.44 times more likely to show altered weight at birth, while neonates with modified weight by the clinical assessment are 11.95 times more likely to show altered weight at birth. Conclusions: Accuracy in the clinical assessment was always higher than in the ultrasound method, especially in low weight newborns.

Background and Objectives. Fetal weight evaluation in utero is a significant component in obstetric practices. The present study aims to estimate the fetal weight (EFW) by evaluating two available formulas using ultrasound parameters and comparing them with actual birth weight (ABW) after delivery. The accuracy and efficacy of both EFW formulas in detecting intrauterine growth retardation (IUGR) and macrosomia were also compared in our local sample of the population. Methods. The cross-sectional study included 100 pregnant women aged 20–45 years from the Kamrup district admitted to Guwahati Medical College and Hospital, Guwahati, Assam. The data were analyzed using Microsoft Excel and SPSS version 16. The EFW at term was calculated using Shepard’s formula and Hadlock’s formula. Differences in means are compared using the one-way ANOVA or Kruskal–Wallis test and paired t-test. The accuracy of the two procedures was evaluated using mean absolute error (MAE) and mean absolute percentage error (MAPE). A p value<0.05 was considered significant. Results. The present study included 100 pregnant women aged 21–38 years with term or postterm pregnancies subjected to ultrasonographic evaluation within 72 hours of delivery. The mean (±s.d.) EFW by Shepard’s formula was 2716.05 (±332.38) g and Hadlock’s formula was 2740.44 (±353.23) g, respectively. For Hadlock’s formula, MAE ± s.d. was found to be higher (overall 84.59 ± 76.54) specifically in the weight category less than 2500 (106.42 ± 88.11) as compared to Shepard’s (overall MAE ± s.d = 79.86 ± 64.78, and among ABW < 2500 g, MAE ± s.d = 65.04 ± 61.02). The overall MAPE of Hadlock’s formula was 3.14% and that for Shepard’s formula was 2.91%, and the difference was not statistically significant. Both Shepard’s formula and Hadlock’s formula had a sensitivity of 92.85% in detecting IUGR, but Hadlock’s method had higher specificity (66%), higher PPV (86.67%), and higher NPV (80%). Conclusion. The ultrasonographic evaluation of fetal weight helps predict fetal birth weight precisely and can influence obstetric management decisions concerning timing and route of delivery, thus reducing perinatal morbidity and mortality.

Background: Correlation of actual fetal weight with clinically and ultrasonographically detected macrosomia cases among diabetic mother is very essential for the management of the neonates. Objectives: The purpose of the present study was to correlate actual fetal weight with clinically and ultrasonographically detected macrosomia cases among diabetic mother. Methodology: This cross-sectional study was carried out in inpatient Department of Obstetrics and Gynecology and in outpatients Department of Radiology and Imaging, BIRDEM during the period of April 2005 to March 2007. Pregnant women with diagnosed diabetes mellitus (DM) or gestational diabetes mellitus (GDM) selected for caesarean section or induction of labour, gestational age 236 weeks having 23700 gm by clinical method were included in this study. First clinical estimation of fetal weight was done by the investigator then Radiologist estimated the fetal weight without knowing the EFW by clinical method. The actual birth weight was estimated after the birth of the babies. Result: The mean (+SD) age of the patients was 30.8±5.1 years ranged from 20 to 40 years. A significant correlation (r=0.5081; p<0.05) was found between clinically estimated fetal weight (gm) and actual birth weight (macrosomia) (gm). Significant correlation (r=0.6199; p<0.05) was found between sonographically estimated fetal weight (gm) and actual birth weight (macrosomia) (gm). Significant correlation (r=0.4863; p<0.05) was found between clinically estimated fetal weight (gm) and sonographically estimated fetal weight (gm). Conclusion: The study findings indicate that clinical method can be used instead of ultrasonography for prediction of macrosomia in diabetic mother Journal of Science Foundation 2018;16(2):38-44

Background and Objectives: The accuracy with which the estimation of fetal weight (EFW) at term is determined is useful in order to address obstetric complications, since it is a parameter that represents an important prognostic factor for perinatal and maternal morbidity and mortality. The aim of this study was to determine the role of the experienced observers with other variables that could influence the accuracy of the ultrasound used to calculate EFW at term, carried out within a period of seven days prior to delivery, in order to assess interobserver variability. Materials and Methods: A cross-sectional study was performed including 1144 pregnancies at term. The validity of the ultrasound used to calculate EFW at term was analyzed using simple error, absolute error, percentage error and absolute percentage error, as well as the percentage of predictions with an error less than 10 and 15% in relation to maternal, obstetric and ultrasound variables. Results: Valid predictions with an error less than 10 and 15% were 74.7 and 89.7% respectively, with such precision decreasing according to the observer as well as in extreme fetal weights. The remaining variables were not significant in ultrasound EFW at term. The simple error, absolute error, percentage error and absolute percentage error were greater in cases of extreme fetal weights, with a tendency to overestimate the low weights and underestimate the high weights. Conclusions: The accuracy of EFW with ultrasound carried out within seven days prior to birth is not affected by maternal or obstetric variables, or by the time interval between the ultrasound and delivery. However, accuracy was reduced by the observers and in extreme fetal weights.

Abstract Background: Hematological reference intervals are used for medical decision tools for interpretation of numerical test results. Establishing of hematological interval among newborn babies is very important for the diagnosis of malignancy, anemia, bleeding disorders, and various infections. There is no locally established hematological reference intervals in Ethiopia. Thus, the aim of this study is to established locally determined hematological reference interval among full-term newborns.Methods: A cross sectional study was conducted from February to May 2019 among 151 apparently healthy full-term newborns at Gondar University Hospital. About 3ml of cord blood was obtained for analysis of Hematological parameters and determined by using Sysmex KX-21N (Sysmex Corporation Kobe, Japan) automated analyzer. Median, 2.5th and 97.5th percentiles were computed.Result: Males to female’s ratio was almost equal. All hematological parameter had no statistically significant difference between males and females. The delivery types were not influenced its hematological values. The reference interval of white blood cells, red blood cells, platelets, hemoglobin, hematocrit, mean cell volume, and mean cell hemoglobin were (7.64-22.16) x109/l, (3.69-5.47)x1012/l, (132.74-413.4) x109/l, (13.32-19.64) g/dl and (39.42-58.06)%, (91.6-113.22)fl, and (30.48-38.02)pg, respectively.Conclusion: All hematological reference interval was established from full-term newborns at University of Gondar hospital was different from other studies in Nigeria, Iraq, Pakistan, Nepal, Saudi Arabia and Iran. Therefore, own determined reference value is very important for the clinicians to correctly diagnosis the patients at health facility levels.
