BackgroundBlood loss during and after total knee arthroplasty (TKA) can lead to substantial morbidity and the need for blood transfusions. There are several methods to minimize blood loss and decrease transfusion rates in patients undergoing TKA. Tranexamic acid, an antifibrinolytic agent with known efficacy for achieving these goals, is combined with tourniquets to reduce bleeding in arthroplasty surgeries. Our study investigated the effects of various combinations of tranexamic acid and tourniquet use on bleeding in knee arthroplasty in 558 patients.AimWe aimed to determine the method that would provide the least blood loss and transfusion need in knee arthroplasty surgery.MethodsBetween January 2018 and December 2022, 558 patients aged between 55 and 85 years underwent TKA surgery for grade 4 gonarthrosis in our clinic, and their decrease in hemoglobin value and whether they were transfused or not were analyzed. The patients were divided into four groups based on use of tranexamic acid and tourniquet. Demographic variables and patient data (body mass index, INR values, and preoperative hemoglobin values) were recorded.ResultsThere were 558 patients with a mean age of 68.19 (67 ± 6.949) years. In group 1, tranexamic acid was not used in 128 patients and tourniquet was used only during cementation; in group 2, in 132 patients, tranexamic acid was not used and tourniquet was used throughout the surgery; in group 3, in 158 patients, tranexamic acid was used and tourniquet was used throughout the surgery; in group 4, in 140 patients, tranexamic acid was used and tourniquet was used only during cementation. The decrease in hemoglobin value and transfusion rate was lowest in group 3 and highest in group 1. Besides, there was a greater decrease in hemoglobin value in group 2 than in group 4 and the transfusion rate was similar.ConclusionsThis clinical study showed that using tranexamic acid and a tourniquet throughout surgery significantly reduced the decrease in hemoglobin value and the need for transfusion.Copyright © 2024 Copyright: © 2024 Nigerian Journal of Clinical Practice.
