The aim of this study was to determine the accuracy of established ultrasound EFW formulae to identify small and large for gestational age fetuses when used after 35 weeks gestation. The study evaluated the accuracy of estimation of fetal weight with ultrasound machine at term. Methods. I am bit worried now and would like to know from mamas who already delivered or yet to deliver what their ultrasound weights were and weight after giving birth. The clinical importance of accurate fetal weight estimation at term is currently unquestionable. Fetal weight estimation is of key importance in the decision-making process for obstetric planning and management. Aim and Objectives . Sometimes the estimate is further out than this, though this is the typical range of accuracy. Methods: This retrospective study evaluated the precision of ultrasound fetal weight estimation in 756 pregnancies complicated by gestational diabetes between 2002 and 2016. Another nuanced way of putting it is that about 95% of the time, fetal weight estimates are within a 15-18% range of the actual weight. Objective To compare the accuracy of routine ultrasonic and clinical birth weight estimation. The accuracy of ultrasound estimated fetal weight has improved in the last decade, though a lack of consistency remains evident. In order to achieve more accurate prenatal fetal weight This is more pertinent in a setting where women book late for antenatal care. Total 255 patients who presented in radiology department for antenatal ultrasound at term pregnancy were recruited in our study. National implementation of a rigorous audit programme would likely improve accuracy further, and increase the confidence and clinical value of the method. Accuracy and reliability of ultrasound estimation of fetal weight in women with a singleton term pregnancy December 2019 DOI: 10.18203/2320-1770.ijrcog20196042 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. Background . Ultrasound fetal biometry is routinely used to calculate estimated fetal weight (EFW). Background. Objectives: To evaluate different formulas for estimating fetal weight in diabetic pregnancies. So around 5% of the time the estimate will be very inaccurate. Methods The study sample included 1717 women with singleton pregnancies, admitted in early labor with an ultrasonic estimated fetal weight (EFW) performed during the preceding week. study to assess the diagnostic accuracy of ultrasound estimation of fetal weight in low birth weight fetuses in term pregnancies keeping actual birth weight as gold standard. examination, Fetal weight estimation, Leopold’s manoeuvres, Normal weight, Overweight Background 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 [ 1–9]. The mean age of all Abstract. The literature is inconsistent on the accuracy of measurements with either ultrasound or clinical examination, known as Leopold’s manoeuvres, shortly before term. However, it is yet to be found a fetal weight estimation formula that it can be simultaneously accurate and simple, excluding time-consuming ultrasound parameters. OBJECTIVES Late onset fetal growth restriction is often missed and is responsible for most intrauterine deaths. AIM OF THE STUDY: The aim of the study is to assess fetal weight by clinical methods using Johnson’s formula and Dare’s formula and by ultrasound, using Hadlock’s Hello,Yesterday I had an ultrasound at 39.2 weeks and baby weight is estimated to be 8 lbs 3 ounces and is in 95 percentile.
