Evaluation of the Early Administration of Tranexamic Acid in Geriatric Hip Fractures in the Emergency Department: A Retrospective Study.

Introduction Tranexamic acid (TXA) administration perioperatively has demonstrated efficacy in reducing postoperative drops in hemoglobin levels and the need for transfusions among patients with peritrochanteric hip fractures. This study aims to perform a retrospective analysis to assess the impact on hemoglobin levels by comparing patients with fragility hip fractures who received TXA in the ED, in addition to the standard perioperative TXA dose, with those who did not receive TXA in the ED. Methods This study retrospectively reviewed 64 patient records from May 2020 to May 2021 at a Level II trauma center that were classified into two groups: patients who received one gram (g) of TXA in the ED, within five hours of injury (new protocol), or patients who received no TXA in the ED (old protocol).
