Effect of intravenous ferric carboxymaltose supplementation in non-anaemic iron deficient patients undergoing hip and knee arthroplasty
Vol 34, Issue 4S3, 2020
Abstract
Preoperative anaemia and non-anaemic iron deficiency are independent risk factors for perioperative blood transfusion, morbidity, and mortality. Although the efficacy to treat anaemia with iron infusion before elective surgery has been widely studied, the literature offers few data about the efficacy of treating iron deficient, non-anaemic patients before elective surgery. This retrospective study assessed the effect of preoperative ferric carboxymaltose (FC) administration on the concentration of Haemoglobin (Hb) in iron deficient, non-anaemic individuals following total knee or hip arthroplasty. A treatment group of 83 non-anaemic iron deficient individuals scheduled for arthroplasty were administered a 1000mg FC infusion over 15 minutes 4 weeks prior to surgery. In the control group (n=62) FC was not administered preoperatively. No individual from either group was given any iron supplement following the pre-operative visit. Blood tests were performed and analysed 4-weeks before surgery, on admission, and then 2-days, 4-days and 4-weeks postoperatively. Number of blood transfusions performed and adverse events were recorded. Hb concentration did not change substantially after iron supplementation prior to surgery. No difference in the number of blood transfusions was observed. In the treatment, group postoperative Hb concentration recovered significantly more quickly compared to control (p=0.0047). No adverse event was reported. The administration of FC in non-anaemic iron deficient individuals quickens the restoration of Hb concentration following THA or TKA procedures.
