Background: Tranexamic acid (TXA) has been used in the management of bleeding. We are conducting a retrospective cohort study to analyse the effect of intravenous TXA infusion on the surgical outcomes of geriatric hip fracture cases which undergoes proximal femoral nail antirotation.  Methods: In this study, 364 patients who had undergone proximal femoral nail antirotation between January 2018 and December 2019 in United Christian Hospital have been recruited. Two-hundred thirteen patients were recruited in controlled group and 151 patients were recruited in TXA group. One gram of TXA acid was injected intravenously on induction of anaesthesia and before surgical incision. Outcomes including length of stay, operation time, intraoperative blood loss, haemoglobin and haematocrit drop and post-operative blood transfusion have been measured. Results: There was a reduction in operative time, intraoperative blood loss, post-operative haemoglobin and haematocrit drop and post-operative blood transfusion in TXA group, with a reduction in the intraoperative blood loss (Controlled group: 97.8 ±  67.7 ml, TXA group: 76.0 ± 71.4, Difference −22.3%, p-value: 0.0036) and post-operative haematocrit drop (Controlled group: 0.04 ± 0.03, TXA group: 0.03 ± 0.03, Difference −25%, p-value: 0.05) being statistically significant. The length of stay is not statistically significant between the two groups. TXA is an antifibrinolytic agent which acts by binding to plasminogen which inhibits plasma formation. It has a potential reduction in blood loss in major operations.  Conclusion: Intravenous TXA infusion helps to reduce blood loss in a patient undergoing proximal femoral nail antirotation. It is safe to use in the geriatric group of patients. We would recommend the usage of TXA infusion to improve the surgical outcome.
