Extensive hemorrhage is a significant cause of mortality in trauma patients. Tranexamic acid has been used for controlling bleeding in cardiovascular surgeries and dental manipulations in patients with hemophilia. However, in traumatic patients with bleeding, its use dates back to more recent years. This study aims to examine the effects of this drug on reducing mortality and blood transfusion rate in trauma patients with significant hemorrhage. A total of 60 patients with significant trauma-related hemorrhage (systolic blood pressure < 90 mmHg/heart rate > 110/min) from the emergency department of Imam Reza Hospital (Tabriz, Iran), were randomized in two groups. The case group received intravenous Tranexamic acid (1 g in 10 min and then 1 g over 8 h). The control group received placebo. Rate of transfusion and rate of one-month mortality were compared between the study groups. The mean ICU stay and overall hospitalization times did not have significant difference between two groups (p<0.05). Transfusion of packed cells was 6.03±1.50 and 6.03±1.22 units in case and control groups respectively. Transfusion of fresh frozen plasma (FFP) was 2.50±1.36 and 3.03±0.96 units in case and control groups respectively (p=0.09). Transfusion of platelets was 0.40±0.20 1.33±0.31 units in case and control groups respectively (p=0.01). Three patients (10%) in the case group and 4 patients (13.3%) in the control group were expired (p=0.50). Tranexamic acid is safe and effective in reducing platelet transfusion rate in patients with trauma-related significant hemorrhage. However, transfusion need and mortality would not reduce by its use in trauma patients.
