current transmission

Last reviewed 01/2018

Current transmission as a result of high voltage electrical injury can result in damage to many tissues:

  • surface injury: full-thickness injury at the sites of entry, exit and contact with the source
  • skeletal muscle:
    • deep muscle damage may be massive and not suggested by often minimal surface injury
    • damage to muscles within the compartment of a limb results in swelling in a closed system and the potential for a compartment syndrome
    • prophylactic fasciotomy should be considered if there is a potential for compartment syndrome
  • heart: cardiac arrest
  • gastrointestinal tract:
    • perforation of bowel
    • intestinal ileus
  • lungs:
    • apnoea
    • burns to lung parenchyma
  • kidneys: acute renal failure due tubular deposition of myoglobin and haemoglobin released from muscle and erythrocytes respectively
