Oral and Intravenous Iron in Patients Postoperative Cardiovascular Surgery Under Extracorporeal Circulation

Summary

Anaemia is a common postoperative problem of cardiovascular surgery after cardiopulmonary bypass (CPB). Because of this the need for hemoderived blood transfusions is high. The purpose of this study was to compare the clinical efficacy of intravenous and oral iron in anaemia and the impact of the iron on the transfusion rate in postoperative cardiovascular surgery under extracorporeal circulation.
