Abstract
Objectives: Total shoulder arthroplasty (TSA) represents a major orthopedic procedure with significant blood loss and transfusion rates up to 43%. Tranexamic acid (TXA), a synthetic amino acid derivative, functioning by inhibiting the conversion of plasminogen to plasmin, has been proven to reduce blood loss in total knee or hip arthroplasty. However, very few studies exist regarding shoulder arthroplasty. The aim of the present review is to evaluate its effectiveness in shoulder arthroplasty. Materials and methods: A meticulous electronic search was performed to find articles reporting the results of TXA administration in TSA or reverse total shoulder arthroplasty (RTSA). Patients' demographics, dose and timing of TXA administration, the type of control group, mean hemoglobin reduction, transfusion rate and total blood loss were evaluated. A total of eight studies including 981 patients were identified. Five hundred and thirty patients (group 1) received TXA, while the remaining 451 comprised the control group (group 2). Results: The mean postoperative reduction in hemoglobin in group 1 was found to be 2.14 g/dL (SD=0.62), compared to 2.71 g/dL (SD=0.57) of group 2; p-value <0.0001. Transfusion rate in group 1 was found to be 1.9%, compared to 4.9% in group 2; p-value=0.009. Total blood loss was found to be 714.6 mL (SD=410.4) in group 1, compared to 911.8 mL (SD=529.7) in group 2; p-value <0.0001. Conclusion: The present review has shown that TXA administration in shoulder arthroplasty has effectively reduced blood loss, postoperative hemoglobin decline and need for transfusion. More research is needed, since optimization of route, timing and dosage of TXA remain to be determined.
