1. The method for carrying out a surgical procedure wherein an electrode is electrosurgically excited to create an arc for cutting tissue of an animal, comprising the steps of:

  • determining an anticipated range of resistance values exhibited by said tissue when confronted by said electrode from a low value to a high value;

    providing a said electrosurgical cutting electrode;

    providing an electrosurgical generator connectable in electrical excitation relationship with said cutting electrode and having a resistance load verses power characteristic effective to sustain creation of said arc at said electrode when confronting said tissue throughout said range of resistance values;

    anesthetizing said animal by parenterally administering a solution of a local anesthetic agent and biocompatible diluent at the site of said tissue, said solution exhibiting a resistivity of value effective to maintain at least said low value of resistance when infiltrated within said tissue; and

    then carrying out said procedure while electrosurgically exciting said electrode from said electrosurgical generator.
