Gangrene : Overview, symptoms, causes, diagnosis and treatment

Description:

Gangrene is a condition that occurs when body tissue dies. It is caused by a loss of blood supply due to an underlying illness, injury, and/or infection. Fingers, toes, and limbs are most often affected, but gangrene can also occur inside the body, damaging organs and muscles. – PowerPoint PPT presentation

Gangrene

Gangrene
  • Gangrene of hands or feet occurs when tissues of
    the body part dies which occurs because the
    tissues did not get enough blood from the
    circulatory system of a person and fingers, toes,
    and limbs are most often affected, but gangrene
    can also occur inside the body, damaging organs
    and muscles.

Types of Gangrene
  • There are three types of gangrene which have
    been found by the doctors, which are as follows
  • Dry Gangrene
  • Wet Gangrene
  • Gas Gangrene
  • These are the major types of Gangrene, in which
    the conditions are as follows
  • Dry Gangrene Dry gangrene is caused when one of
    the body parts isn't getting enough oxygen.
    Eventually, the body part will start to
    deteriorate and die. With dry gangrene, the skin
    is closed and there is no evidence of infection.
  • Wet Gangrene Wet gangrene happens when the body
    tissues become infected with some type of
    bacteria. The tissues react to the presence of
    the bacteria by growing moist and breaking down.
    This process causes the death of the tissues.
    This is more of an emergency than dry gangrene
    because of the possibility of infection spreading
    to other parts of the body.
  • Gas Gangrene Bacteria called Clostridia cause
    gas gangrene. This bacterium creates an infection
    that causes gas bubbles and toxins to develop
    inside the affected area. The resulting gases
    cause tissue death.

Symptoms of Gangrene
  • There are various symptoms of gangrene which are
    as follows
  • Dry gangrenea)The affected area becomes cold
    and numb. b)Initially, the affected area becomes
    red. c)Then, it develops a brown
    discoloration. d)Finally, it becomes black and
    shriveled.
  • Wet or moist gangrene a)The affected area
    becomes swollen and decays. b)It is extremely
    painful. c)Local oozing occurs. d)It produces a
    foul-smelling odor. e)It becomes black. f)The
    affected person develops a fever.

  • Gas gangrene a)The wound is infected. b)A
    brown-red or bloody discharge may ooze from the
    affected tissues. c)Gas produced by Clostridia
    may produce a crackling sensation when the
    affected area is pressed. d)It becomes swollen,
    and blisters may develop. e)Pain in the affected
    area is severe. f)The affected person develops
    fever, increased heart rate, and rapid breathing
    if the toxins spread into the bloodstream.

Treatments of Gangrene
  • There are various types of treatment prescribed
    by doctors according to the condition of patient,
    which are as follows
  • Antibiotics The doctor may prescribe antibiotics
    if bacteria are present. These are typically
    given intravenously, or through a needle directly
    into the blood stream.
  • Vascular Surgery For people with poor
    circulation that results in gangrene, vascular
    surgery (surgery on the arteries or veins) may be
    recommended in order to improve the flow of blood
    through the veins to body tissues.
  • Hyperbaric Oxygen Chamber Placing a person with
    gas gangrene in a special oxygen-rich environment
    can slow the growth of bacteria. This allows the
    skin to begin healing. It also brings oxygen to
    the damaged tissue to promote healing.
  • Tissue Debridement In serious gangrene cases,
    the dead tissue or body part may need to be
    removed. This process is called debridement.
    Debridement can be done with surgery tools or
    with chemicals. The goal with this type of
    surgery is to remove the affected areas so the
    infection can no longer spread and to rid the
    body of the dead tissue.
  • Amputation People who must have part of an arm
    or leg amputated due to gangrene may be fitted
    with a prosthesis, or artificial limb, to replace
    the missing body part.
