Opioid-volatile anesthetic synergy: a response surface model with remifentanil and sevoflurane as prototypes.

abstract：:The effect of temperature (37 degrees C, 28 degrees C, and 18 degrees C), 160 mg/kg lidocaine, and 40 mg/kg thiopental on the efflux of cellular potassium in the cerebral cortex during complete global ischemia was examined. Cerebral ischemia was induced in dogs on cardiopulmonary bypass circulation by stopping the pum...
