Functional brain imaging during anesthesia in humans: effects of halothane on global and regional cerebral glucose metabolism.

abstract：:The effects of epinephrine 1/200,000 as an adjuvant to epidural morphine were investigated in three healthy male volunteers, during 26-h observation sessions. Peak blood concentrations of morphine were 44 +/- 12.9 ng/ml after plain morphine and 13.7 +/- 6.7 ng/ml after epinephrine-morphine. Cutaneous hypalgesia was mo...
