Keywords: Blood loss, pneumatic tourniquet, postoperative pain, total knee arthroplasty, tranexamic acid.
Objectives: The aim of this study was to evaluate the effects of tranexamic acid (TXA) administration on bleeding control and to compare its utilization with and without simultaneous use of conventional pneumatic tourniquets during total knee arthroplasty (TKA).
Patients and methods: Between January 2017 and December 2017, a total of 204 patients (23 males, 181 females; mean age: 66±6.9 years; range, 45 to 86 years) who underwent TKA for Stage 4 gonarthrosis were retrospectively analyzed. The patients were divided into two groups as those with (n=110) and without (n=94) pneumatic tourniquet use. Tranexamic acid (1 g) was administered intravenously to all patients in both study groups. Intra- and postoperative blood loss were calculated, and postoperative pain was evaluated by a Visual Analog Scale. Demographic and clinical data were compared between the study groups.
Results: The amount of total blood loss and postoperative blood loss were significantly higher in the tourniquet group than that in the no-tourniquet group (589.4±69.5 mL vs. 490.8±55.2 mL and 326±56 mL vs. 164±35.5, respectively; p<0.001 for both). Intraoperative blood loss was significantly higher in the no-tourniquet group (326.9±42.9 mL vs. 263.5±53.8 mL, respectively; p<0.001). The pain score at 24 h was significantly higher in the tourniquet group (p<0.001).
Conclusion: Total blood loss and postoperative pain were significantly higher among patients in whom a tourniquet was used during TKA. Therefore, the routine use of tourniquets with TXA should be reconsidered.
