Electrosurgery is the use of high-frequency alternating electrical current applied to tissue to cut, coagulate, desiccate or fulgurate during a surgical procedure. The current heats tissue at the cellular level, causing cell death and protein coagulation at moderate temperatures and rapid vaporization at higher temperatures, letting a surgeon cut tissue and control bleeding at the same time. It differs from simple electrocautery, which uses a heated probe rather than passing current through the tissue itself. Electrosurgical devices are used across most surgical specialties, from dermatology to neurosurgery, in both hospital operating rooms and outpatient settings, mainly to reduce blood loss during an operation.

How is electrosurgery different from simple electrocautery
Electrosurgery passes electrical current directly through the tissue itself, while electrocautery only applies heat from an already hot probe.

Electrosurgery is the application of a high-frequency (radio frequency) alternating polarity, electrical current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue.
In Group: Surgical Techniques and Technology, Introduction
Electrosurgery is the application of a high-frequency (radio frequency) alternating polarity, electrical current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue. (These terms are used in specific ways for this methodology-see below.) Its benefits include the ability to make precise cuts with limited blood loss.
