Intravenous Iron Does Not Effectively Correct Preoperative Anemia in Cardiac Surgery: A Pilot Randomized Controlled Trial

In this randomized controlled trial, Padmanabhan and colleagues focused on the ability of iron given intravenously to increase hemoglobin levels before elective cardiac surgery, comparing this with iron given orally. The study included 50 anemic patients who were scheduled for cardiac surgery. Ferritin levels increased significantly in patients with intravenous iron administration. Iron administration did not influence hemoglobin level, regardless of the method of administration.
