Electrical burn on hand. 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 ...
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 ]
Electrical burns or injuries are classified as high voltage (greater than or equal to 1000 volts), low voltage (less than 1000 volts), or as flash burns secondary to an electric arc. [2] The most common causes of electrical burns in children are electrical cords (60%) followed by electrical outlets (14%).
When electric current flows through tissues or bone, it produces heat that causes electrical burns. [36] 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 ...
Thermal trauma is any burn-related injury that can potentially lead to serious outcomes. There are various causes of thermal trauma, including fire, radiant heat, radiation, chemical, or electrical contact, [1] that can affect a person in many ways based on factors from anatomical and physiological factors.
Contact injury occurs when the person is touching the object that is hit. [1] Direct strikes make up about 5% of injuries. [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 that cause permanent disabilities, such as spinal cord injuries, can have severe effects on self-esteem. [68] [69] Disfiguring injuries can negatively affect body image, leading to a lower quality of life. Burn injuries in particular can cause dramatic changes in a person's appearance that may negatively affect body image. [70] [71] [72]
Moderate and high-power lasers are potentially hazardous because they can burn the retina of the eye, or even the skin. To control the risk of injury, various specifications – for example ANSI Z136 in the US, EN 60825-1/A2 in Europe, and IEC 60825 internationally – define "classes" of lasers depending on their power and wavelength.
