Electrosurgery and hemostasis
Electrosurgery and hemostasis
An electrosurgical device for hemostasis is essential in dermatologic surgery.17 In electrosurgery, high-frequency, alternating electric current is passed through the skin to generate heat. It requires a power supply and a handpiece for the electrode. A sterile dedicated electrode tip should be used for each patient. Electrosurgery includes electrofulguration, electrodessication, electrocoagulation, electrosection, and thermocautery. Electrosurgery may be monoterminal, monopolar, or bipolar. A wide variety of devices are available for electrosurgical hemostasis. For a full discussion of electrosurgery and hemostasis, see Chapter 16.
The use of a smoke evacuator should be considered for several reasons. The smell of burning skin can be disconcerting to patients, and the plume may lead to respiratory irritation in patients and staff. In addition, while there is no documented transmission of infectious diseases through surgical smoke, there is a theoretical potential for viral particle transmission.18,19
