  1. Why are electrical burns so dangerous?
    Most of the destruction is internal because the route of least electrical resistance follows nerves, blood vessels, and fascia.

    • Common sequella:
    • cardiac dysthymias, myoglobinuria, acidosis, renal failure
  2. Acid or alkali burns worse?
    • Alkali
    • The body cannot buffer the alkali thus allowing them to burn for much longer
