Effect of Postoperative Ferric Carboxymaltose

The Catholic University of Korea80 enrolled

Overview

The primary purpose of this study is to evaluate the safety and efficacy of postoperative intravenous ferric carboxymaltose in patients with anemia undergoing Simultaneous Bilateral Total knee replacement in terms of Quality of life (QOL) and objective measures (Hemoglobin and Iron parameters).

Both preoperative and postoperative anaemia are common in patients undergoing total knee arthroplasty. Allogeneic RBC (red blood cell) transfusion and anaemia are related with higher postoperative mortality and morbidity. It is important to have a strategy of patient blood management. Hb(hemoglobin) level of 10 g/dl will be used as a cut-off value for our study. In postoperative period in total knee arthroplasty for osteoarthritis, consented patients with postoperative anemia will be administered Ferinject® or placebo (normal saline) based on the results of randomization. Study Group: Ferinject® administration as IV drip infusion or undiluted bolus injection with a minimum administration time of 15minutes (for 1000mg(milligram) single administration) for body weight ≥50 Kg (kilogram) or 6 minutes (for 500mg(milligram) single administration) for body weight \< 50Kg( kilogram) . Control Group: Placebo in the form of normal saline administration as same time period as equivalent Ferinject® administration. IV drip infusion or undiluted bolus injection with a minimum administration time of 15 minutes (200mL(milliliter) as infusion or 20mL(milliliter) as bolus injection) for body weight ≥50 Kg ( kilogram) or 6 minutes (100mL normal as infusion or 10mL(milliliter) as bolus injection) for body weight \<50 Kg (kilogram).
