Electrosurgery is the application of high-frequency alternating current (AC) in surgery to achieve various thermal tissue effects including cutting, desiccation and coagulation. It is different from electrocautery, which is the passive transfer of heat to the tissue with no current passing through it.
Electrocautery uses DC, whereas electrosurgery uses AC to avoid electrolysis and a high frequency to avoid the Faradic effect of nerve and muscle stimulation. This effect ceases at frequencies above 100 kHz. Because the frequencies commonly used in electrosurgery are greater than 500 kHz, which are similar to radiofrequency (RF), the term RF electrosurgery is used.
