Estimation of fetal weight by fetography
American Journal of Obstetrics and Gynecology, 1977The present studies were designed to estimate fetal weight on the basis of the thesis that the factors which determine body weight include the fetal bone and the amount of fetal soft tissue, i.e., fetal corpulence. Scalp thickness on the fetogram in the vertex presentation was measured, and the ratio of the minimal femur diameter to the thickness of ...

Automatic balance for fetal weight studies
American Journal of Obstetrics and Gynecology, 1976An automatic balance was constructed of aluminum sheet, miniature ball bearings, and a strain gauge. The balance was capable of measuring 1 to 4 kg. with an accuracy of +/- 0.5 Gm. and a 95 per cent response time of less than 0.3 seconds. Fetuses of term ewes were exteriorized and weighed continuously for up to 3 hours.

Prediction of fetal weights in twins
Acta Obstetricia et Gynecologica Scandinavica, 1995Objective. To determine the accuracy of sonographic weight estimation of twin fetuses. Methods In 73 twin‐pregnancies, fetal weight estimation by ultrasound was performed within 7 days prior to delivery. Fetal head biparietal diameter and abdominal circumference were measured.

Estimation of Fetal Weight by Ultrasound
Hormone Research, 1992Estimation of fetal size by ultrasound has supported two recent concepts of fetal growth. Firstly, the normal weight gain is constant from 28 weeks of gestation until several weeks after term; about 27 g/day. Secondly, the average weight of fetuses born preterm is lower than the average weight of fetuses of the same gestational age who remain in utero.

Determination of fetal weight in utero
American Journal of Obstetrics and Gynecology, 1961Abstract 1. 1. The importance of fetal weight in utero as it pertains to the current evaluation of the obstetrical patient is discussed. 2. 2. A review of the literature uncovered no accurate method for determination of fetal weight in utero. 3. 3.

Estimation of fetal weight by ultrasound
Journal of Clinical Ultrasound, 1983AbstractBirth weight (BW) and log10 birth weight (LBW) are expressed as linear, multilinear, parabolic, and polynomial regression functions of the abdominal circumference (AC), and combinations of fetal index measurements, namely, AC and head circumference (HC); biparietal diameter (BPD) and AC; and BPD, HC, and AC.

Validity of ultrasound estimation of fetal weight
Obstetrics & Gynecology, 2000To assess the validity of ultrasound estimation of fetal weight at term.We conducted a prospective observational study whereby all ultrasonic biometric measurements were done by a single observer. Fifty pregnant women at term had ultrasonic measurement of various fetal biometric parameters performed within a week of delivery. Fetal weight was estimated

Fetal Weight and Progression of Diabetic Retinopathy
Obstetrics & Gynecology, 2001To test the hypothesis that progression of diabetic retinopathy in pregnancy is associated with reduced fetal growth and related neonatal morbidity.Women with type 1 diabetes (n = 205) were enrolled before 14 weeks' gestation in a prospective study of diabetes in pregnancy and treated with intensive insulin therapy.

Maternal-Fetal Weight Relationships in Primates
Folia Primatologica, 1973Analysis of maternal-fetal weight relationships in primates based on the regression equation F (fetal weight) = b · M (maternal weight)a indicates that prosimian and anthropoid primates are separated by an allometric shift which can be interpreted as a result of differences in placental structures.

Role of Fetal Length in the Prediction of Fetal Weight
Journal of Ultrasound in Medicine, 2012The purpose of this study was to compare the accuracy of routine fetal biometric indices in the prediction of fetal length and to determine whether more accurate sonographic measures of fetal length can improve the accuracy of fetal weight estimation.The accuracy of the common sonographic fetal biometric indices for predicting fetal length was ...
