Electrical injuries to peripheral nerves.
As people come frequently into contact with electrical power sources, electrical injuries to peripheral nerves are commonly seen. The authors first review the parameters determining the severity and distribution of electrical injury to nerve tissue. These include tissue resistance, tissue susceptibility, current pathway, type of current, current density, duration and size of electrical contact. Subsequently, the pathophysiology of electrical injuries to nerve tissue is reviewed. Such injuries can be the result of thermal damage, vascular impairment, histological or electrophysiological changes in peripheral nerves, or direct mechanical trauma. Each of these types of injuries causes, specific lesions. As these lesions, especially delayed peripheral neurologic injury, can cause medico-legal problems, it is important to emphasize that electroneuromyography must be performed as early as possible.
