Abstract

Background. Peri-operative intravenous administration of iron supplementation seems a good option to reduce allogeneic blood transfusion in major orthopaedic surgery. However, its efficacy in simultaneous bilateral total knee arthroplasty has not been studied. Materials and methods. From December 2014 to May 2015, a total of 72 consecutive patients underwent simultaneous bilateral total knee arthroplasty and received peri-operative intravenous iron supplementation (iron isomaltoside 1000: 600 mg pre-operatively and 400 mg 1 week post-operatively) and intra-articular tranexamic acid (2 g in 20 mL saline at the end of surgery), and were managed with a restrictive transfusion trigger (haemoglobin <7 g/dL). Post-operatively, we observed patients closely for symptoms of anaemia and checked their haemoglobin levels on days 1, 6 and 13 after surgery. Results. The mean baseline haemoglobin level was 13.1 g/dL. The levels remained above 7.0 g/dL on post-operative days 1, 6 and 13 (mean, 11.4 g/dL, 9.9 g/dL and 10.4 g/dL, respectively) in all but one patient who experienced melaena and required allogeneic blood transfusion. Discussion. Intravenous iron supplementation combined with intra-articular administration of tranexamic acid seems to be an effective strategy for reducing the rate of allogeneic blood transfusion in patients undergoing simultaneous bilateral total knee arthroplasty managed with a restrictive transfusion trigger.
