Blood thinner users with head injuries may benefit from platelet transfusions

This study looks at whether giving platelets (cells that help blood clot) to people with severe traumatic brain injuries who are on antiplatelet medications (blood thinners) can improve clotting and stop bleeding in the brain. About 225 adults with certain types of head bleeds will receive a platelet transfusion and then have their blood clotting tested. The goal is to see if this treatment slows or stops the bleed from getting worse.
