Effects of Tranexamic Acid on Intraoperative Bleeding and Surgical Field Visualization During Middle Ear Surgery: A...

Tranexamic acid is an antifibrinolytic agent widely used in several surgical procedures to reduce intraoperative bleeding. Intraoperative bleeding is a crucial problem for the ear surgeon, as it prevents good visualization of the surgical field. The aim of this work was to analyze the relevant literature about the use of tranexamic acid in ear surgery. A literature search was conducted in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement, across 3 databases (Medline, Cochrane, and Google Scholar), with the terms "tranexamic acid," and "ear," and "surgery." Three prospective, randomized, and double-blind clinical trials met the inclusion criteria. Studies were not able to be pooled because of heterogeneity in material, methods of delivery and evaluation, and procedures used. Despite these limitations, all 3 papers found a significant reduction in intraoperative bleeding, allowing a better visualization of the operating field. Despite the scarcity of published trials, tranexamic acid is safe and seems to be useful in reducing intraoperative bleeding in ear surgery, thus improving operative field visualization.
