Protection from local anesthetic-induced convulsions by gamma-aminobutyric acid.

abstract：BACKGROUND:Pain behavior in response to skin incision is developmentally regulated, but little is known about the underlying neuronal mechanisms. The authors hypothesize that the spatial activation and intensity of dorsal horn neuron responses to skin incision differ in immature and adult spinal cord. METHODS:Single w...

abstract：:Fentanyl is used as an analgesic in small doses (1-2 micrograms X kg-1) and as an anesthetic in very large doses (greater than 150 micrograms X kg-1). It has been demonstrated that the effects of fentanyl correlate with its concentrations in plasma. It is important, therefore, to know whether or not the pharmacokineti...
