The cerebral and systemic hemodynamic and metabolic effects of desflurane-induced hypotension in dogs.

abstract：BACKGROUND:Xenon has been shown to be neuroprotective in several models of in vitro and in vivo neuronal injury. However, its putative neuroprotective properties have not been evaluated in focal cerebral ischemia. The purpose of this study was to determine if xenon offers neuroprotection in a mouse model of middle cere...
