Abstract
Summary Ultrasound estimation of FW is a very important aspect of antenatal care & has become an integral part of routine practice in obstetrics. Abnormal values of EFW may be linked with the presence of numerous foetal, maternal & associated with labour complications & may have influence on decision-making regarding pregnancy management. On the one hand, many former studies reported that foetal macrosomia is strongly related with gestational DM & other perinatal complications, including shoulder dystocia, birth canal trauma, asphyxia injuries, meconium aspiration, prolonged labour, humeral & clavicular fractures, brachial plexus palsies or even postpartum haemorrhage. On the other hand, low birth weight may be associated with foetal prematurity or IUGR.The accuracy of sonographic prediction of ABW is related to sonographer’s experience, equipment quality, foetus’ presentation, location of the placenta, foetal sex & the time between weight estimation & delivery. Nonetheless, the role of AFV as a potential factor which may impede the relevance of sonographic FW estimation is still questionable & poorly documented. Amniotic fluid cushions the fetus from traumatic forces, cord compression & pathogens, as well as playing an essential role in fetal lung development. In late pregnancy, AF production is largely dependent on fetal micturition & renal size in the newborn has been shown to bear a significant relationship to birth weight. It is therefore, reasonable to postulate a relationship between sonographically determined AFI &
