Translated article] The efficacy of topical tranexamic acid in reverse shoulder arthroplasty

Abstract

IntroductionTopical tranexamic acid (TXA) has been shown to decrease blood loss in knee and hip arthroplasty. Despite there is evidence about its effectiveness when administered intravenous, its effectiveness and optimal dose when used topically have not been established. We hypothesised that the use of 1.5g (30mL) of topical TXA could decrease the amount of blood loss in patients after reverse total shoulder arthroplasty (RTSA). Material and methodsOne hundred and seventy-seven patients receiving a RSTA for arthropathy or fracture were retrospectively reviewed. Preoperative-to-postoperative change in haemoglobin (ΔHb) and hematocrit (ΔHct) level drain volume output, length of stay and complications were evaluated for each patient. ResultsPatients receiving TXA has significant less drain output in both for arthropathy (ARSA) (104 vs. 195mL, p=0.004) and fracture (FRSA) (47 vs. 79mL, p=0.01). Systemic blood loss was slightly lower in TXA group, but this was not statistically significant (ARSA, ΔHb 1.67 vs. 1.90mg/dL, FRSA 2.61 vs. 2.7mg/dL, p=0.79). This was also observed in hospital length of stay (ARSA 2.0 vs. 2.3 days, p=0.34; 2.3 vs. 2.5, p=0.56) and need of transfusion (0% AIHE; AIHF 5% vs. 7%, p=0.66). Patients operated for a fracture had a higher rate of complications (7% vs. 15.6%, p=0.04). There were no adverse events related to TXA administration. ConclusionTopical use of 1.5g of TXA decreases blood loss, especially on the surgical site without associated complications. Thus, haematoma decrease could avoid the systematic use of postoperative drains after reverse shoulder arthroplasty.
