Bupivacaine does not suppress cardiac sympathetic nerve activity during halothane anesthesia in the cat

Abstract

We conclude that i.v. bupivacaine, unlike i.v. lidocaine, does not suppress CSNA during either normal or high CSNA under halothane anesthesia although i.v. bupivacaine has stronger depressive effects on cardiac conduction than does i.v. lidocaine during deep halothane anesthesia.
