[Therapeutic approach to postoperative anemia].

Postoperative anemia is a common finding in patients who undergo major surgery, and it can affect early rehabilitation and the return to daily activities. Allogeneic blood transfusion is still the most widely used method for restoring hemoglobin levels rapidly and effectively. However, the potential risks of transfusions have led to the review of this practice and to a search for alternative measures for treating postoperative anemia. The early administration of intravenous iron appears to improve the evolution of postoperative hemoglobin levels and reduce allogeneic transfusions, especially in patients with significant iron deficiency or anemia. What is not clear is whether this treatment heavily influences rehabilitation and quality of life. There is a lack of well-designed, sufficiently large, randomized prospective studies to determine whether postoperative or perioperative intravenous iron treatment, with or without recombinant erythropoietin, has a role in the recovery from postoperative anemia, in reducing transfusions and morbidity rates and in improving exercise capacity and quality of life.
