Abstract
INTRODUCTION: Tranexamic acid has been widely used in plastic surgery. However, its efficacy has yet to be fully established. This meta-analysis aimed to determine its effectiveness in aesthetic plastic surgery. METHODS: Following PRISMA guidelines, we conducted a meta-analysis of prospective randomised clinical trials that compared the effects of topical or systematic administration of tranexamic acid versus the control group in aesthetic plastic surgeries. The study was registered on the International Register of Systematic Reviews (PROSPERO) and is available online ( www.crd.york.uk/prospero , CRD42023492585). RESULTS: Eleven studies encompassing 960 patients were included for the synthesis after critical evaluation. Systematic (MD - 18.05, 95% Cl, - 22.01, - 14.09, p < 0.00001) and topical (MD - 74.93, 95% Cl, - 88.79, - 61.07, p < 0.00001) administration of tranexamic acid reduced total blood loss. Topical tranexamic acid reduced drainage output (p < 0.0006). CONCLUSION: Tranexamic acid reduced blood loss in aesthetic plastic surgery. More strictly defined RCTs, using high-quality methodology, are needed to evaluate the advantages and disadvantages of tranexamic acid in aesthetic plastic surgery.
