Popis: Previous studies using a rat brain slice model of cerebral 'ischaemia' (hypoxia and hypoglycaemia) have suggested that volatile anaesthetics may have cerebroprotective potential. In this study, we tested the cerebroprotective profile of four volatile anaesthetics in this model by two independent means: voltammetric measurement of 'ischaemia'-induced dopamine (DA) release and post-'ischaemic' tissue staining with 2,3,5-triphenyltetrazolium chloride (TTC). 'Ischaemia' caused a characteristic pattern of DA release. Halothane, isoflurane and enflurane did not affect the time from onset of 'ischaemia' to the initiation of DA release. However, all three volatile agents significantly increased (P
