Absence of autoregulation of cerebral blood flow during halothane and enflurane anesthesia.

abstract：BACKGROUND:Midazolam is the most commonly used premedication in children. It has been shown to be more effective than parental presence or placebo in reducing anxiety and improving compliance at induction of anesthesia. Clonidine, an alpha(2) agonist, has been suggested as an alternative. Dexmedetomidine is a more alph...
