Ultrasound estimation of fetal weight is a highly influential factor in antenatal management, guiding both the timing and mode of delivery of a pregnancy. Although substantial research has investigated the most accurate ultrasound formula for calculating estimated fetal weight, current evidence indicates significant error levels.

Accuracy of fetal weight estimation is of key importance in antenatal care, as well as in the planning and management of labour and mode of delivery [1,2,3,4,5,6,7,8,9].In order to achieve more accurate prenatal fetal weight estimations and align these with a risk-optimizing mode of delivery, additional tools supporting the standard of use with ultrasound are needed.

There was a significant difference for the head circumference (P = ), the abdominal circumference (P = ), the femur length (P = ) and the estimated fetal weight for both formulae. In the routine estimation of fetal weight with ultrasound, existing regression equation is used to estimate the fetal weight.

Accurate estimation of fetal weight is extensively required by obstetrics doctors, which is particu - larly important when dealing with fetuses with growth restriction or. @article{SciosciaEstimationOF, title={Estimation of fetal weight by measurement of fetal thigh soft‐tissue thickness in the late third trimester}, author={M.

The purpose of this study was to compare the accuracy of different sonographic models for fetal weight estimation. We evaluated 26 different models using sonographic weight estimations.

Nevertheless, the clinicians should exert caution in interpretation when estimated fetal weight is at the extreme end of the weight range. One very important application of ultrasound-based fetal weight estimation is to identify fetuses, which are likely to be in LBW or HBW category.

Ultrasound estimation of fetal weight at term provides vital information for the skilled birth attendants to make decisions on the possible best route of delivery of the fetus. This is more pertinent in a setting where women book late for antenatal care.

In view of this, the present study was conducted to estimate the fetal weight assessed by clinical and ultrasound method and correlating with the birth s: A cross-sectional study was. The accurate estimation of fetal weight by ultrasound is important in the treatment of many complications in pregnancy.

When complications occur at the limits of fetal viability, knowledge of fetal weight will help to assess the likelihood of neonatal survival and hence determine whether to prolong the pregnancy with conservative treatment or to deliver the fetus. 1 Small for gestational age.

A method of estimating fetal weight by ultrasonic measurement of the fetal abdominal circumference is described. Assessment of birth weight predictions on fetuses who were delivered within 48 hours of this measurement showed that the accuracy of predictions varied with the size of the fetus; at a predicted weight of 1 kg, 95 per cent of birth weights fell within g, while at 2 kg, 3 kg.

Ultrasound measurements of the fetus's head, abdomen, and upper thighbone provide a more accurate way to determine size. But unlike weighing the baby on a scale after birth, even the best ultrasound measurements aren't % reliable. There is no method of checking fetal size before delivery can provide more than an estimated fetal weight (EFW).

From a consecutive series of single pregnancies the pregnancies (3% of the hospital population) with ultrasound measurements obtained within 4 days before delivery were. Fetal weight estimation is inaccurate, with poor sensitivity for prediction of fetal compromise.

Several authors have shown the unacceptable level of intra- and interobserver variability in fetal measurement and the impact of errors on growth assessment. The aims of this study were to review the available methods and possible sources of inaccuracy.

Estimation of fetal weight by ultrasound is an important investigation in the management of twin pregnancies because of the high incidence of growth retardation [4], the inaccurate estimation of fetal weight by abdominal palpation, and the common excess.

The purpose of this study was to investigate whether knowledge of ultrasound-obtained estimated fetal weight (US-EFW) is a risk factor for cesarean delivery (CD).

Study Design Retrospective cohort from a single center in of singleton, term live by: The ultrasound method is, however believed to be more accurate than the clinical method, hence >20% of all pregnant women now undergo a third-trimester ultrasound examination specifically for the assessment of fetal growth and fetal weight estimation.

The mean actual birth weight was 3, ± g, while the mean estimated fetal weights by clinical and ultrasound methods were 3, ± g and 3, ± g, respectively (Table 2).Paired -test on mean ultrasonically calculated weight taken before birth of fetus and actual birth weight revealed no significant difference (,).It was also found that actual birth weight was not significantly.

Ultrasound imaging is considered significantly accurate for estimation of fetal weight that can be clinically applicable. It has been documented that ultrasound can determine fetal weight within 10% of actual birth weight in as many as 75% of cases estimated.

The majority of American College of Obstetrics and Gynecology fellows are using ultrasound for fetal weight estimation at term and 84 % are recommending a cesarean section if EFW is greater than  g Birth weight represents the most important risk indicator.

estimated fetal weight (EFW) with the baby’s subsequent weight at birth, for preterm and term gestations. CONCLUSIONS • Ultrasound biometry is overall a quite accurate means for the estimation of fetal weight in routine practice.

• There is no evidence that scan accuracy is any worse at term. Inmagnetic resonance imaging was introduced for the estimation of fetal weight, which is done by measuring the fetal body volume and converting it through a formula to fetal weight. Approximately 10 studies have shown that magnetic resonance imaging is more accurate than 2-dimensional ultrasound imaging in the estimation of fetal weight.Because the estimated fetal weight (EFW) is critical for management decisions, including timing of delivery, it is important to determine the combination of biometric measurements that most accurately estimate the fetal weight in these fetuses.
