Efficacy of preoperative Tranexamic Acid in patients undergoing intertrochanteric hip fracture surgery: A randomized placebo controlled trial
Objective: To determine the efficacy of preoperative Tranexamic Acid (TXA) in reducing perioperative allogenic blood transfusion frequency in patients with intertrochanteric fractures treated with Dynamic Hip Screw (DHS).
Methods: We conducted this placebo controlled double-blinded randomized trial in Orthopaedics & Traumatolgy Division Lady Reading Hospital, Peshawar from 1st January 2020 to 25th December 2022. All patients with intertrochanteric hip fractures fulfilling the inclusion criteria were treated with Dynamic Hip Screw (DHS) and were randomly divided into two equal groups. One group was administered single dose IV Tranexamic Acid (TXA) in a dose of 15mg/kg body weight in 100ml of saline while the other group (Placebo) was given 100 ml normal saline preoperatively. Post-operative Hemoglobin was measured on first, second and third day. The frequency of allogenic blood transfusions in the perioperative period was determined in both groups based upon the transfusion trigger (Hemoglobin 9g/dl). Categorical variables were compared with Chi-square test and mean with Independent sample t-test. P value of <0.05 was considered significant.
Results: The total number of patients in our trial were 200 which were equally but randomly allocated into TXA group and Placebo group each containing 100 patients. The mean age of the patients in TXA group was 48.16±1.75 years and the age of patients in the Placebo group was 48.35±1.60. The baseline demographic and clinical variables of both groups were identical (p< 0.05). The average preoperative hemoglobin was 11.5±4.2 g/dl in TXA group and 11.3±2.4g/dl in the Placebo group (p>0.05). The frequency of allogenic blood transfusion was significantly lower (p<0.05) in TXA group (13%, n=13) than in the Placebo group (41%, n=41).
Conclusion: Tranexamic acid (TXA) significantly reduces the frequency of peri operative allogenic blood transfusion in patients undergoing Dynamic Hip Screw (DHS) for intertrochanteric fractures.
