Lemakalim, a potassium channel agonist, reverses electrophysiological impairments induced by a large dose of bupivacaine in anaesthetized dogs.

Abstract

We have examined the ability of lemakalim to correct bupivacaine-induced cardiac electrophysiological impairment in an experimental electrophysiological model in closed-chest dogs. Two groups (n = 6) of pentobarbitone-anaesthetized dogs were given atropine 0.2 mg kg-1 i.v., and bupivacine 4 mg kg-1 i.v. over 10 s. Group 2 received also lemakalim 0.03 mg kg… (More)
