MAROTO-RODRIGUEZ, R; MARCOS, S; PAYO, J e CORDERO-AMPUERO, J. Topical use of tranexamic acid in total hip arthroplasties: retrospective analysis of its advantages. Acta ortop. mex [online]. 2022, vol.36, n.2, pp.110-115. Epub 28-Ago-2023. ISSN 2306-4102. https://doi.org/10.35366/108126.
Introduction:
Intravenous (IV) tranexamic acid (TXA) has shown its usefulness to prevent postsurgical anemia, but few studies have analyzed its topical administration. Seven years ago, we implemented a new topical administration (moistening three gauzes with 1.5 g of TXA) in our primary total hip arthroplasties (THA). The objective of this study was to compare blood loss, hospital stay and complications without the use of TXA, topical use or 10 mg/kg IV plus topical.
Material and methods:
Consecutive retrospective series of 274 patients undergoing CTA (mean 70 years [59-76], 59% women) operated from 2014 to 2019. Loss of hemoglobin and hematocrit, blood transfusions, hospital stay, thromboembolic complications were compared and 30-day mortality among three groups: non-tranexamic (44.2%), topical (45.6%), topical + IV (9.9%).
Results:
After 24 and 48 hours, hemoglobin and hematocrit decreased less (p < 0.05) in patients treated with TXA (topical and/or IV). Blood transfusion was required in 32% of patients without TXA, 12% of those treated with topical TXA only (RR = 3.24 [95% CI: 1.69-6.20]), and 0% of patients who received IV TXA (p = 0.005) (RR = 4.07 [95% CI: 2.14-7.48]). Hospital stay was reduced three days with TXA (p < 0.001). We have not observed any adverse effects related to TXA.
Conclusions:
The use of TXA in CTA significantly reduces anemia, transfusions and hospital stay without increasing complications. Isolated topical TXA (hemostatic pads) is less effective than topical IV + topical use, but both significantly improve anemia, transfusions, and hospital stay compared to no use.
