Early Postoperative Intravenous Iron Versus Oral Iron for the Treatment of Anemia Following Cardiac Surgery: A Randomized Controlled Trial

However, secondary end points suggest it may improve hemoglobin levels and reduce the prevalence of postoperative iron deficiency. These findings warrant further investigation in larger trials to confirm the clinical effectiveness of early postoperative IV iron.
