Randomized Controlled Trial
Effect of a free radical scavenger, edaravone, in the treatment of patients with aneurysmal subarachnoid hemorrhage.
It is hypothesized that cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH) is induced by free radicals released from a subarachnoid clot. This study therefore investigated the effect of a new free radical scavenger, edaravone, in the treatment of patients with aneurysmal SAH. ⋯ We found a trend toward a lesser incidence of DINDs and a lesser incidence of poor outcome caused by cerebral vasospasm in edaravone-treated patients. It might therefore be suggested that edaravone is a useful agent for the treatment of aneurysmal SAH.
