Arms Assigned Interventions
Active Comparator: Ferrous fumarate, Ferri-6®, Oral tablet
In the O-group, women had to take 3 ferrous fumarate tablets (Ferli-6®) everyday with a total of 200 mg of elemental iron per day from 33 weeks gestation until delivery. Emphasizing and monitoring for compliance to the treatment protocol were carried out.

Experimental: iron sucrose, Venofer®, intravenous drug
Women in the IV-group received 500 mg iron sucrose (Venofer®, Vifor International AG, St. Gallen, Switzerland) divided into three weekly administrations. Two doses of 200 mg iron sucrose were given at 33 and 34 weeks gestation while the remaining (100 mg) was infused at gestation of 35 weeks. Thereafter, women in this group received no further iron therapy until delivery. In preparation, 200 mg of iron sucrose was diluted into 100 ml of 0.9% saline solution.

Detailed Description:

Despite routine antenatal oral iron supplementation, the prevalence of iron deficiency anemia (IDA) in the 3rd trimester of pregnancy in developing countries remains high. Apparently, intravenous iron sucrose appears to be safe and efficient in treating within a short period. From literature review, no study of intravenous iron for IDA treatment has been carried out in the third trimester of pregnancy. This research aims to compare the efficacy of body iron storage replenishment at 3 weeks as labor may take place at this point in some women. In this study,500 mg intravenous iron has been given weekly instead of every other day for the sake of patient's convenience in the hope that parenteral iron may become another alternative for treatment of pregnant women with iron deficiency anemia who have difficulties or failures with oral iron.
