Estimation of Fetal Weight by Ultrasound

Hormone Research, 2008
Estimation 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.

Fetal weight/placental weight ratio and perinatal outcome

American Journal of Obstetrics and Gynecology, 1984
The relationship of placental size to perinatal outcome was investigated in a population of low-risk infants. A trimmed and drained placenta was weighed for each of 417 low-risk infants, and for 108 infants whose intrapartum course was complicated only by compression of the umbilical cord.

A Global Reference for Fetal-weight and Birth-weight Percentiles

Obstetric Anesthesia Digest, 2011
Definition of small for gestational age in various populations worldwide remains a challenge. References based on birthweight are deficient for preterm births, those derived from ultrasound estimates might not be applicable to all populations, and the individualised reference can be too complex to use in developing countries.

Accuracy of Fetal Weight Estimation by Ultrasound

Asia-Oceania Journal of Obstetrics and Gynaecology, 1986
AbstractThe main objective of this study was to assess the accuracy of fetal weight estimation by ultrasound. 124 patients were scanned and the estimated fetal weight calculated by the equation of Warsof revised by Shepard was compared with actual fetal weight of the newborns, who were born within one week of the last scan.

Estimating Fetal Weight in the Management of Macrosomia

Obstetrical & Gynecological Survey, 2000
The purpose of this review is to examine the evidence that, including estimates of fetal macrosomia in patient care, will decrease adverse perinatal outcomes. A literature search for the years 1980 to 1999 was used. Shoulder dystocia and brachial plexus injuries occur more often in macrosomic than in non-macrosomic neonates.

Fetal weight estimation in twin pregnancies

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1989
In this study the fetal weight was estimated by ultrasound measurements of the biparietal (BPD) and abdominal diameters (AD) in 154 consecutive twin pregnancies. In 80 twins an attempt to estimate fetal weight was made 0-4 days before delivery (26% of all twins examined).

Fetal weight and intrauterine position in rats

Teratology, 1969
AbstractFetal weight data from 28 litters of Wistar rats were analyzed for the effect of position in the uterine horn on fetal weight. The deviation of each fetus from the mean weight of all fetuses in a uterine horn was divided by the standard deviation of the mean. The standard scores thus obtained were studied for position effect. A pattern of fetal

Fetal weight and membrane tensile strength

American Journal of Obstetrics and Gynecology, 1964
Abstract 1. 1. The tensile strength per unit width of membranes was studied in 62 cases of premature delivery and late abortion, 27 cases of premature rupture of the membranes, and 101 normal term deliveries. 2. 2. The average tensile strength of the membranes from normal term deliveries was 0.207 Kg.

Automatic balance for fetal weight studies

American Journal of Obstetrics and Gynecology, 1976
An 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.
