Abstract

INTRODUCTION The placenta is a multifunctional organ of mainly foetal in origin with pleiotropic roles during foetal growth. The health of the mother, the placenta, and the fetus's predefined genetic development potential all affect intrauterine growth; of these, placental illness has been demonstrated to be the most significant clinically relevant risk factor. Placental weight is one-fifth of the fetal weight, and aberrant variance is linked to poor perinatal outcomes, as has historically been established .our study was done to measure the role of placental thickness in predicting low birth weight. METHODS 200 cases were recruited for study who came for antenatal check up to department of OBG, JJMMC, Davangere, at 32 weeks of gestation and were followed up at 36 weeks and after delivery. Placental thickness measured at the site of umbilical cord insertion by two dimensional ultrasonography, at 32 and 36 weeks and correlated with post-delivery birth weight of the fetus. RESULTS Study subjects had thick and thin placenta at 32 weeks and at 36weeks, had maximum birth weight < 2.5 kg, whereas subjects having normal placental thickness had more birth weight above 2.5 kg.
