Adrenergic vasoconstriction in peripheral nerves of the rabbit.

abstract：:Dexmedetomidine (DMED) is a highly selective centrally acting alpha 2-adrenergic agonist thought to provide significant sedation without appreciable ventilatory effects. This double-blind, placebo-controlled experiment evaluated four dose levels of DMED (0.25, 0.5, 1.0, and 2.0 micrograms/kg intravenously over 2 min) ...
