Electrosurgical safety

Technological advances in safety and the performance of electrosurgical units (ESUs) have made the ESU the most common piece of electrical equipment in the OR. The constant presence of the ESU in the OR increases the potential for patient injury that is associated with the use of any piece of electrical equipment. To prevent injuries related to the use of an ESU, the perioperative nurse must understand the types of current used, types of ESUs available, and potential complications and have a working knowledge of safe practices for using this equipment in the perioperative setting.
