A histologic and electronic evaluation of electrosurgical currents: nonfiltered full-wave modulated vs. filtered current.

A controlled system for examining the tissue alteration and healing of electrosurgically produced wounds was established. Standardization of width, depth, stroke, amperage, average voltage, and wave form was achieved. A histologic comparison of tissue alteration and healing produced by a conventional blade and two electrosurgical currents was carried out. The need for standarization of instrumentation and clinical procedures is discussed.
