Single Versus Multi-Dose Oral Tranexamic Acid in Patients at High Risk for Blood Transfusion After Total Joint Arthroplasty

Summary

As tranexamic acid (TXA) becomes more prevalent, all patients are receiving the same dose regardless of their pre-operative risk of transfusion. Therefore the aim of the study is to determine whether or not repeated dosing of oral TXA reduces the post-operative reduction in hemoglobin, hematocrit, number of transfusions, and post-operative blood loss following primary TKA and THA surgeries in patients with low pre-operative hematocrit and high risk for transfusion. The investigators hypothesize that a multi-dose TXA regimen will significantly minimize post-operative blood loss and transfusion requirements compared to the use of a single dose regime.
