The pathophysiology and medical treatment of electrical injuries in the field were considered. Specific topics that were addressed included low voltage accidents (rescue and resuscitation) and high voltage accidents (rescue, resuscitation, and fluid therapy). Only injuries associated with generated, alternating current were considered. Rescue and treatment procedures included deenergizing the victim, cardiopulmonary resuscitation and emergency cardiac care where appropriate, and restoring fluid volume in high voltage injuries with significant loss of intravascular fluids. The author concludes that many victims of electrical injury can be saved if prompt and effective rescue and treatment procedures are employed. Knowledge of electrical safety was emphasized as a means of avoiding personal injury, particularly with regard to incorporating basic principles of such safety in training programs for emergency medical technicians.
