Abstract
The effect of 4 anaesthetic regimes on blood pressure and survival was investigated during repeated episodes of cerebral ischaemia in the rat induced by diathermy of the vertebral arteries and reversible occlusion of the carotid arteries. The best results were obtained with inspired halothane with neuromuscular blockade and artificial ventilation, followed in order by halothane, intravenous alphaxolone/alphadolone, and intraperitoneal urethane with spontaneous ventilation.
