Abstract:
Surgical electrodes, passed through metal suction-irrigation devices, pose significant risks for unrecognized visceral burns through capacitively coupled current using monopolar electrosurgery. Plastic cannulas (and reducers) should be avoided with the metal suction-irrigation electrode; an all-metal trocar cannula confers limited safety. With surgeon education and advances in engineering, the potential for unrecognized visceral injury with capacitive coupling can be eliminated.
