Neural regulation of vascular tone and cold induced vasoconstriction in human finger skin.


Finger skin blood flow was measured by a laser Doppler during control conditions, after neural blockade at the finger base by prilocaine and after localized anaesthesia of the skin by lidocaine introduced iontophoretically into the finger skin. Vasoconstriction was achieved by local cooling of the finger and by iontophoretic administration of norepinephrine… (More)
