The reversal of the ischemic effects of epinephrine on a finger with local injections of phentolamine

V Markovchick et al. J Emerg Med. 1991 Sep-Oct.

Abstract

The use of phentolamine (Regitine) as a specific competitive antagonist of epinephrine by virtue of its alpha-blocking properties is well known. Its use via digital nerve block infiltration has been described in cases of IV infiltration of sympathomimetics. We discuss a recent case of local and direct infiltration of phentolamine along the course of the digital arteries and directly into the thumb tuft to reverse the local ischemic effects of epinephrine.
