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]
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 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.
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%).
Injuries to humans elicit an elaborate response including emergency medicine, trauma surgery (illustrated), and pain management. Injury in humans has been studied extensively for its importance in medicine. Much of medical practice, including emergency medicine and pain management, is dedicated to the treatment of injuries.
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.
Three elements are required for an electrocution to occur: (a) a charged electrical source, (b) a current pathway through the victim, (c) a ground. The health hazard of an electric current flowing through the body depends on the amount of current and the length of time for which it flows, not merely on the voltage. However, a high voltage is ...
