The most common injuries include electric shocks, burns, and other events. The most typical location of this kind of burn is on an ECG electrode, also known as a return or dispersive electrode, or on any portion of the body in contact with an electrosurgical unit return channel, such as an arm, chest, or leg. When sparks from the electrosurgical unit meet an oxidant, they may ignite flammable materials. In most cases, these mistakes result in burn-site infection. A hospital stay for the patient will probably be extended if this occurs.
