Electrical injury

Definition:

An electrical injury can occur to the skin or internal organs when a person is directly exposed to an electrical current.

Alternative Names:
Electrical shock
Considerations:

The human body is a good conductor of electricity. Direct contact with electrical current can be fatal. While some electrical burns look minor, there still may be serious internal damage, especially to the heart, muscles, or brain.

About 1,000 people die annually of electric shock in the United States.

The outcome of an electric shock to an individual depends on the intensity of the voltage to which the person was exposed, the route of the current through the body, the victim's state of health, and the speed and adequacy of the treatment.

Electric current can cause injury in three main ways:

Cardiac arrest due to the electrical effect on the heart.
Muscle, nerve, and tissue destruction from a current passing through the body.
Thermal burns from contact with the electrical source.

Causes:

Accidental contact with exposed parts of electrical appliances or wiring
Young children biting or chewing on electrical cords, or poking metal objects into the electrical outlet
Lightning
Flashing of electric arcs from high-voltage power lines
Machinery or occupational-related exposures
