What is Gangrene?
  • Gangrene is the death of tissue that begins when
    a section of the body loses its blood supply.
  • Its often the result of a serious accident in
    which an arm or leg is crushed.
  • Less commonly, it follows an internal blockage,
    such as a clogged or obstructed artery.

There are two major types of gangrene
  • Dry gangrene . This variety is free of infection.
    It is usually brought on by a blood clot,
    frostbite, or poor circulation that causes the
    tissues to become dry and shriveled.

  • Wet gangrene (also called gas gangrene) . In this
    form of the disease, dead tissue becomes a
    breeding ground for bacteriatypically
    Clostridium , which thrives in the absence of
    oxygencausing the area to become moist and
    foul-smelling.

Signs and Symptoms
  • The skin may look pale at first, then become red
    or bronze, and finally turn dark red or purple.
  • Infection makes the skin warm and swollen
  • Inflammation at the site of the infection can
    become extremely painful as the tissue swells.
  • A foul-smelling brown-red or bloody discharge may
    drain from the afflicted tissues.

  • In other parts of the body, the infection soon
    produces sweating, fever, and increased heart
    rate. Left untreated, the victim will develop a
    shock-like syndrome with decreased blood
    pressure, kidney failure, coma, and finally
    death.

How to you treat Gangrene before it gets worse.
  • Because gangrene spreads rapidly, immediate
    treatment is essential. The goal is to prevent
    infection from spreading.
  • Any dead tissue must be removed at once.
  • Antibiotics are needed to keep bacteria from
    attacking surrounding tissues.
  • Restoring blood supply.
  • In severe cases, it may lead to amputation.
