Objective To investigate the efficacy and safety of emergency administration of tranexamic acid (TXA) in reducing perioperative blood loss and blood transfusion rate in elderly patients with intertrochanteric femoral fractures. Methods  A retrospective analysis was conducted on the clinical data of 102 elderly patients with intertrochanteric femoral fractures who were admitted between October 2023 and May 2025 and met the selection criteria. Patients were divided into two groups based on whether TXA was administered in the emergency department: the TXA group (patients received a single intravenous infusion of 1 g TXA immediately upon emergency admission, n=50) and the control group (no TXA was used in the emergency department, n=52). There was no significant difference in baseline data between the two groups (P>0.05), including age, gender, body mass index, American Society of Anesthesiologists (ASA) classification, AO/Orthopaedic Trauma Association (AO/OTA) fracture classification, underlying comorbidities, prothrombin time, activated partial thromboplastin time, fibrin degradation products, D-dimer, bone mineral density T-score, time from injury to admission, time from admission to surgery, hemoglobin (HB), and hematocrit (HCT) levels at emergency admission. The following parameters were collected and analyzed statistically: changes in HB and HCT on the day before surgery (compared with values at emergency admission); hidden blood loss (HBL) on the day before surgery; total blood loss (TBL) on postoperative day 1, day 3, and during the entire perioperative period; in-hospital blood transfusion rate; and incidence of complications such as thrombosis. Results There was no significant difference in operation time between the two groups (P>0.05). All patients were followed up 3-12 months (mean, 6.6 months). On the day before surgery, the decreases in HB and HCT in the TXA group were significantly lower than those in the control group (P<0.05). The HBL on the day before surgery and perioperative TBL in the TXA group were significantly lower than those in the control group (P<0.05), whereas there was no significant difference in TBL on postoperative day 1 or day 3 between the two groups (P>0.05). The in-hospital blood transfusion rate in the TXA group (34.0%) was significantly lower than that in the control group (55.8%, P<0.05). During hospitalization and follow-up, no complication such as deep vein thrombosis of the lower extremities, pulmonary embolism, surgical site infection, or allergic reactions occurred in either group. Intermuscular venous thrombosis occurred in 4 patients (8.0%) in the TXA group and 5 patients (9.6%) in the control group, with no significant difference in incidence between the two groups (P>0.05). Conclusion  Elderly patients with intertrochanteric femoral fractures experience significant blood loss due to initial trauma. Emergency administration of TXA can reduce trauma-induced preoperative HBL, perioperative TBL, and in-hospital blood transfusion rate without increasing the incidence of thromboembolic events, thus proving safe and effective.
