Clinical efficacy of local infiltration of lidocaine and tranexamic acid application in tonsillar region on postoperative pain and bleeding during tonsillectomy: prospective, randomized, double-blind controlled study

Background Anesthetic techniques are designed to minimize intraoperative surgical bed bleeding which is a major problem that may interfere with precision, surgery duration, or postoperative wound healing. The main reason for reoperation and/or mortality in children who have had tonsillectomies is post-tonsillectomy hemorrhage. We evaluate the local application effect of tranexamic acid and lidocaine local infiltration in the tonsillar bed during tonsillectomy surgery on postoperative analgesia and bleeding.Results FLACC scores showed a statistically significant reduction in the first 24 h in group T (P < 0.05). Post-tonsillectomy hemorrhage was significantly minimized in group T. No complications were recorded following the local application of tranexamic acid and local lidocaine infiltration inside the tonsil bed.Conclusions Local infiltration of lidocaine provides adequate postoperative analgesia, and tranexamic acid application during tonsillectomy surgery minimizes postoperative bleeding and shortens surgery duration.Trial registration This study was preregistered with the Clinical Trials Registry (NCT05817474).
