ABSTRACT
To determine whether advanced placental calcification is associated with impaired placental function by assessment of different grades of placental calcification in relation to cord blood NRBCs count, a marker for chronic hypoxia. Nucleated Red Blood Cells [NRBCs] from cord blood of 200 singleton term non -asphyxiated neonates were compared with cord blood NRBCs of 51 term singletons proved to have 2ed and 3ed Grade placental calcification by ultrasound examination Foetal weight and Apgar score were also assessed in different groups. Grade III placental calcification [n=30] was not associated with a significant difference in NRBC counts compared to group one [n=200]: mean 2.45.S.D.2.4I and mean 2.40, SD 2.12 respectively [P> 0.8]. These result illustrated that advanced grades of placental calcification dose not Jeopardize fetal oxygenation, as evidenced by the non significant finding of NRBC counts in different groups, and the non Significant difference in fetal out come by comparing fetal weigh and Apgar scores for different groups
