title: Neuroprotection with anaesthetic agents.
abstract: The term 'neuroprotection' is used to refer to any prophylactic measure that is initiated during the peri-ischaemic period in order to improve neuronal survival. Cell death after ischaemia has an immediate, necrotic and a delayed, apoptotic origin. The major biochemical mechanisms that are involved in this process include transmembrane ionic fluxes and intracellular calcium increase, excitotoxicity, free radical formation, peroxynitrite production, release of inflammatory mediators, mitochondrial dysfunction, cytochrome c release, and activation of caspases and transcription factors. Strategies of neuroprotection essentially impact on those biochemical pathways. The label 'neuroprotectant' requires that the therapy has basic properties that are consistent with potential mechanisms of neuroprotection, and that conclusive results are available from animal studies that can be converted into clinical benefit. The present review focuses on neuroprotective effects of anaesthetics and is based on the most recently published reports.
