Abstrakt:	Background: Resection of intracranial meningioma has been associated with significant blood loss. Providing a clear surgical field and maintaining hemodynamic stability are the major goals of anesthesia during meningioma surgery. Tranexamic acid has been used to reduce blood loss in various neurosurgical settings with limited evidence in literature. A randomized, double-blind, and placebo-controlled trial was conducted to evaluate the efficacy of tranexamic acid on blood loss, coagulation profile, and quality of surgical field during resection of intracranial meningioma. Methods: Thirty patients aged 18-65 years undergoing elective meningioma resection surgery were given either tranexamic acid or placebo (0.9% saline), tranexamic acid at a loading dose of 20 mg/kg, and infusion of 1 mg/kg/h during surgery. The intraoperative blood loss, coagulation profile, and the surgical field using Likert scale were assessed. Results: The patients in tranexamic group had significantly decreased intraoperative blood loss compared to the placebo group (616.42 ± 393.42 ml vs. 1150.02 ± 416.1 ml) ( P = 0.02). The quality of the surgical field was better in the tranexamic group (median score 4 vs. 2 on Likert Scale) ( P < 0.001). Patients in tranexamic group had an improved coagulation profile and decreased blood transfusion requirement (p=0.016). The blood collected in closed suction drain in 24 h postsurgery was less in the tranexamic acid group compared to placebo group (84.7 ± 50.4 ml vs. 127.6 ± 62.2 ml) ( P = 0.047). Conclusion: Tranexamic acid bolus followed by infusion reduces perioperative blood loss by 46.43% and blood transfusion requirement with improved surgical field and coagulation profile in patients undergoing intracranial meningioma resection surgery.
