Background: Iron-deficiency anemia is the most common nutritional cause of anemia in pregnancy and is often responsible for puerperal anemia. Puerperal anemia can impair postpartum maternal and neonatal well-being.
Objective: To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III)-hydroxide polymaltose.
Methodology: A randomized controlled study in which postpartum women with moderate iron-deficiency anemia were randomized into treatment with either a single total-dose intravenous iron dextran or with daily single doses of oral iron(III)-hydroxide polymaltose tablets for 6 weeks. Effects on hemoglobin concentration using either method were compared at 6 weeks postpartum. Analysis was per protocol using SPSS version 17 for windows. P-values ≤0.05 were considered significant.
Results: Two hundred eighty-four women were recruited for the study: 142 women received single total dose intravenous infusion of iron dextran while 142 received daily oral iron(III)-hydroxide polymaltose tablets. Approximately 84.0% (237/282) completed the study and were analyzed including 81% (115/142) of those randomized to injectable iron therapy compared to 85.9% (122/142) of those randomized to oral treatment. The proportions of women who had attained hemoglobin concentration of at least 10 g/dL by the 6 weeks postpartum visit did not differ significantly between cases and controls (95.7% vs 94.3%; P=0.73). Similarly, the mean increases in hemoglobin following either therapeutic route were comparable (1.03±0.56 g/dL for intravenous iron and 0.97±0.46 g/dL for the oral group; P=0.42).
Conclusion: Single total-dose intravenous iron for treatment of puerperal iron-deficiency anemia was as effective as daily single doses of ferric iron tablets. For puerperal patients with iron-deficiency anemia in whom compliance with and tolerability of oral iron are not certain, a single total-dose intravenous iron can be safely offered.
