Halothane-induced changes in the release and disposition of norepinephrine at adrenergic nerve endings in dog saphenous vein.

abstract：BACKGROUND:The authors hypothesized a difference in plasma-effect site equilibration, depicted by a first-order constant k(e0), depending on the injection rate of propofol. METHODS:Sixty-one patients received 2.5 mg/kg propofol given as a bolus or as a 1-, 2-, or 3-min infusion. The Bispectral Index was used to monito...
