Overview
Brief 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.
Detailed Description
Prospective double dummy triple blind study of 159 patients undergoing CPB; randomised in 3 groups treated with iron intravenously (iv) (group I), with iron orally (group II) controlled with placebo (group III). Patients from group I were treated with iv Iron sucrose , three doses of 100 mg of iv iron every 24 hours during postoperative hospitalization and 1 pill/24 h of oral placebo during the first month after discharge. Group II was programmed to receive 1 iron pill orally every 24 hours pre and postoperatively and up to one month after discharge and a placebo while hospitalized. Group III was programmed to receive an oral and iv placebo pre and postoperatively. Variables were collected preoperatively, at operation room and at Intensive Care Unit admission and discharge, at postoperative floor discharge and at one month after surgical discharge.
