An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [ 2 ] [ 3 ] The injury depends on the density of the current , tissue resistance and duration of contact. [ 4 ]
An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. [1] [2] Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. [3]

[1] The mechanism of the injuries may include electrical injury, burns from heat, and mechanical trauma. [1] Diagnosis is typically based on history of the injury and examination. [1]
Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans.
While electrical injuries primarily result in burns, they may also cause fractures or dislocations secondary to blunt force trauma or muscle contractions. [24] In high voltage injuries, most damage may occur internally and thus the extent of the injury cannot be judged by examination of the skin alone. [ 24 ]
Electric bicycle injuries increased by nearly 100% and electric scooter injuries went up by more than 45% annually. Experts say it underscores the importance of wearing a helmet.
Electrical burns cause tissue damage and need immediate medical attention. Electric shocks can result in injuries such as muscle spasms, palpitations, nausea, vomiting, collapse, and unconsciousness. [35] Faulty electrical connections and damaged electrical equipment can lead to an electric shock to workers and to others at or near the ...
