Electrosurgery is a term used to describe multiple modalities that use electricity to cause thermal destruction of tissue through dehydration, coagulation, or vaporization. The two types of electrosurgery most commonly used are high-frequency electrosurgery and electrocautery.
High-frequency electrosurgery refers to four different methods: electrocoagulation, electrodesiccation, electrofulguration, and electrosection. These methods involve high-frequency alternating current, which is converted to heat by resistance as it passes through the tissue.
What is electrosurgery used for?
Electrosurgery is a
technique often used in dermatologic surgery to provide
superficial or deep coagulation or cutting of the skin. The skin has
poor conducting properties for the electrical flow of energy.
Therefore, this energy builds up and is converted into heat.
Does electrosurgery hurt?
Electrosurgery cuts extremely rapidly when compared to a diode laser. When on the proper setting, hemostasis is almost immediate. Assuming the electrode is cleaned frequently while operating, the cutting consistency, speed, and depth of cuts are very good. After cutting, the wound is nearly painless.
How does electrosurgery induce tissue effect in surgery?
During electrosurgery, the back and forth movements of the high-frequency alternating current make the cellular ions oscillate to create frictional heat. Thus, electrical energy is converted to mechanical then to thermal energy intracellularly. Such generated heat produces the thermal tissue effects.
