Temperature dependence of the potency of volatile general anesthetics: implications for in vitro experiments.

abstract：BACKGROUND:Although inhalation anesthetic agents are thought to impair cerebral autoregulation more than intravenous agents, there are few controlled studies in humans. METHODS:In the first group (n = 24), dynamic autoregulation was assessed from the response of middle cerebral artery blood flow velocity (Vmca) to a t...
