The response of cerebral blood flow (CBF) to drug-induced hypotension was measured in 20 patients who underwent craniotomy for clipping a aneurysm following subarachnoid hemorrhage. A modified intravenous xenon-133 injection technique used monitor CBF. In 15 patients, CBF increased significantly with hypotension, and only one developed late neurological deficit. five fell halothane-induced four delayed deficits. Measurement the intraoperative may reveal those at greatest risk developing deficits require more intensive postoperative monitoring early use induced hypertension technique.
