Hemodynamic predictors of myocardial ischemia during halothane anesthesia for coronary-artery revascularization.

abstract：BACKGROUND:Propofol may produce amnesia by affecting encoding. The hypothesis that propofol weakens encoding was tested by measuring regional cerebral blood flow during verbal encoding. METHODS:Seventeen volunteer participants (12 men; aged 30.4 +/- 6.5 yr) had regional cerebral blood flow measured using H2O positron ...
