Efficacy of tranexamic acid on operative bleeding in endoscopic sinus surgery: A meta-analysis and systematic review.

This meta-analysis showed that the systemic administration of tranexamic acid could decrease operative time and blood loss intraoperatively, increasing the satisfaction of surgeons. It did not provoke intraoperative hemodynamic instability, postoperative emetic events, or coagulation profile abnormality. Only a small number of studies were enrolled, so further trials are needed to confirm the results of this study. Laryngoscope, 129:800-807, 2019.
