RESUMO

Objectives / Hypothesis: Tonsillectomy, with or without adenoidectomy, is one of the most common surgical procedures in pediatric otolaryngology. Bleeding is a potential complication. We evaluated the efficacy of intravenous tranexamic acid in reducing intraoperative bleeding volume in children who underwent adenotonsillectomy. The secondary outcome was the incidence of immediate bleeding and bleeding to the tenth day. Study Design: Double-blind, randomized clinical trial. Methods: Ninety-five children of both sexes between four and twelve years of age who underwent adenotonsillectomy were allocated to receive intravenous tranexamic acid in the preoperative and at the eight and the sixteenth hours of the postoperative periods. Bleeding volume was measured in milliliters (mL) at the end of the procedure. Results: There was no statistically significant reduction in bleeding volume with the use of tranexamic acid (mean ± standard deviation, 135.13 ± 71.44 [tranexamic acid] versus 158.21 ± 88.09 [placebo]; P = 0.195). No difference was observed in the incidence of postoperative bleeding in the ten postoperative days. Conclusions: There is no benefit in the use of tranexamic acid for reducing bleeding during the transoperative period of adenotonsillectomy in children. More studies are required to evaluate the benefit of tranexamic acid in postoperative bleeding.
