What this trial studies

This study investigates the effectiveness of tranexamic acid in reducing intraoperative blood loss during the resection of large meningiomas, which are brain tumors. Patients undergoing elective surgery for meningiomas larger than 5 cm will receive either a continuous infusion, a single infusion of tranexamic acid, or a placebo. The study aims to determine if tranexamic acid can significantly decrease the average blood loss, which is typically over 1000 ml in these procedures. By focusing on a specific neurosurgical population, this research seeks to fill a gap in existing literature regarding the use of tranexamic acid in neurosurgery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 undergoing elective surgery for supratentorial meningiomas larger than 5 cm.

Not a fit: Patients with allergies to tranexamic acid, a history of thrombotic disease, chronic kidney disease, or those on anticoagulation treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to reduced blood loss during surgery, shorter hospital stays, and improved patient outcomes.

How similar studies have performed: Previous studies have shown that tranexamic acid can effectively reduce blood loss in other surgical contexts, but its application in neurosurgery remains less explored.
