Abstract:
INTRODUCTION:Tranexamic acid (TXA) is a synthetic derivative of the amino acid lysine that inhibits fibrinolysis by blocking lysine-binding sites on plasminogen, which contribute to reduced bleeding, the need for transfusion and mortality. Although there is reliable evidence of the efficacy of TXA, its effects on other important outcomes, adverse events, including thrombotic events and seizure, remain uncertain. METHODS AND ANALYSIS:We will conduct a systematic review and meta-analysis of randomised controlled trials with the objective of evaluating the incidence of thrombotic adverse events and seizure and how the effect of TXA varies by dose and underlying disease. We will include patients with bleeding in any underlying disease. We will search MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials for randomised controlled trials. The planned date of our systematic search is 1 June 2020. We will follow the recommendations of the Cochrane Collaboration and the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Subgroup and sensitivity analyses will be performed to explore residual heterogeneity and inconsistency. Meta-regression analysis will be carried out to investigate the association between the incidence of adverse events and the TXA dose. The risk of systematic errors (bias) and random errors will be assessed and the overall quality of evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach. ETHICS AND DISSEMINATION:This study will not involve primary data collection, and formal ethics approval will therefore not be required. We aim to publish this systematic review in a peer-review journal. TRIAL REGISTRATION NUMBER:UMIN000039611.
