The Optimal Dosing Regimen for Tranexamic Acid in Revision Total Hip Arthroplasty .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
The Optimal Dosing Regimen for Tranexamic Acid in Revision Total Hip Arthroplasty: A Multicenter Randomized Clinical Trial.
J Bone Joint Surg Am. 2020 Nov 4;102(21):1883-1890.One hundred seventy-five patients undergoing revision total hip arthroplasty were randomized to receive one of four tranexamic acid (TXA) regimens: a single 1-g intravenous (IV) dose (n=43), a double 1-g IV dose (n=40), a combined 1-g IV and 1-g topical dose (n=46), or three oral doses totaling 1,950 mg (n=46). The primary outcome was the reduction in postoperative hemoglobin levels. Secondary outcomes included calculated blood loss, transfusion rates, and venous thromboembolism incidence. Outcomes were assessed during hospitalization. Overall, the results demonstrated no significant differences among the four regimens in hemoglobin reduction, calculated blood loss, or transfusion rates. A single venous thromboembolism event was recorded, with no differences between groups. These findings suggest that all four TXA regimens are equally effective in minimizing perioperative blood loss in revision total hip arthroplasty, allowing surgeons to choose the most practical regimen for their practice.
