Background: Recovery of patients with traumatic brain injury largely depends on the reduction in secondary brain damage. The present study aims at investigating the effect of Tranexamic Acid (TXA) administration within the first hours of brain trauma in the emergency department (ED). Methods: This randomized, double-blind, placebo-controlled clinical trial was carried out in patients with subdural and epidural hemorrhage. Patients with any type of bleeding were assigned into two groups of TXA and 0.9% normal saline as placebo. The rate of intracranial hemorrhage after surgery was assessed by CT-scan and amount of hemoglobin (Hb) was measured immediately before surgery and after 6 hours of surgery. Results: A total of 80 participants were randomly assigned into four groups of 20 people. There was a significant difference in the mean of intraoperative bleeding during surgery in patients receiving TXA and placebo in both SDH (Subdural hematoma) and EDH (Epidural Hemorrhage) groups (P= 0.012). The Hb drop amount had no significant difference with placebo (P< 0.0001). No complications were observed in any of the intervention and control groups during the study as well. Conclusion: The use of TXA may reduce bleeding, however, based on the results of this study, such effect was not statistically significant in controlling the epidural and subdural hemorrhage, but clinical trials with a higher sample size are suggested for further investigation in this regard.
Introduction: Controlling of secondary traumatic brain injuries (TBI) is necessary due to its salient effect on the improvement of patients with TBI and the final outcomes within early hours of trauma onset. This study aims to investigate the effect of intravenous tranexamic acid (TAX) administration on decreased hemorrhage during surgery. Methods: This double-blind, randomized, and placebo-controlled trial was conducted on patients referring to the emergency department (ED) with IPH due to brain contusion within 8 h of injury onset. The patients were evaluated by receiving TXA and 0.9% normal saline as a placebo. The following evaluation and estimations were performed: intracranial hemorrhage volume after surgery using brain CT-scan; hemoglobin (Hb) volume before, immediately after, and six hours after surgery; and the severity of TBI based on Glasgow Coma Score (GCS). Results: 40 patients with 55.02 ± 18.64 years old diagnosed with a contusion and intraparenchymal hemorrhage. Although the (Mean ± SD) hemorrhage during surgery in patients receiving TXA (784.21 ± 304.162) was lower than the placebo group (805.26 ± 300.876), no significant difference was observed between two groups (P=0.83). The (Mean ± SD) Hb volume reduction immediately during surgery (0.07 ± 0.001 and 0.23 ± 0.02) and six hours after surgery (0.04 ± 0.008 and 0.12 ± 0.006) was also lower in TXA group but had no significant difference (P = 0.89 and P = 0.97, respectively). Conclusion: Using TXA may reduce the hemorrhage in patients with TBI, but this effect, as in this study, was not statistically significant and it is suggested that a clinical trial with a larger population is employed for further investigation.
