Electrosurgery is a popular surgical technique in which high-frequency, low-voltage electrical energy produced by an electrosurgical unit is used to excise abnormal tissue with hemostasis. In this study, electrosurgical units were critically evaluated for safety, electrical specifications, design, and performance characteristics. Quantitative electrical specification and histologic thermal artifact measurements and qualitative observations were recorded for 13 electrosurgical units representing 11 manufacturers. The Aspen Sabre 180 and Laserscope e10 were considered exemplary units based on safety criteria alone. Cut-mode thermal artifact was less than 10 μm for the Cooper Leep 6000, Laserscope e10, and Utah Finesse. A maximum fulguration distance of greater than 0.5 mm was demonstrated by the Gyne-Tech Autolepe 2000 and 4000, Laserscope e10, and the Elmed ESU 30. For gynecologic electrosurgery, the Aspen Sabre 180 and Laserscope e10 were rated best, followed closely by the Utah Finesse and Finesse II and the Gyne-Tech Autolepe 4000. Dermatologic electrosurgery may be well accomplished with many of the electrosurgical units, except as noted.
