An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1,000 deaths per year due to electrical injures are reported in the United States, with a mortality rate of 3-5%. Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. They can exclusively cause surface damage, but more often tissues deeper underneath the skin have been severely damaged. As a result, electrical burns are difficult to accurately diagnose, and many people underestimate the severity of their burn. In extreme cases, electricity can cause shock to the brain, strain to the heart, and injury to other organs.
