Results:In the group-A(iron sucrose group), mean pre-infusion Hb levels was 9.09 ±0.83 gm/dl. Mean increase in Hemoglobin (Hb) was 10.75 ±1.097 gm/dl after 4 weeks of infusion and 11.06 ±0.866 gm/dl at delivery (p < 0.001). In group-B (iron dextran group) pre-infusion haemoglobin was 8.735 ±0.956 gm/dl and the mean increase in hemoglobin was 10.613 ±1.22 gm/dl at 4-week while mean increase of 10.859 ±1.11 gm/dl at the time of delivery (p < 0.001).
