1. GANGRENE
TYPES OF GANGRENE

2. GANGRENE
Necrosis of tissue with superadded putrefaction
is known as Gangrene.
There are 2 main forms of gangrene :-
1) Dry Gangrene and
2) Wet Gangrene,
Gas gangrene is a variant of wet gangrene.

3. DRY GANGRENE
Dry gangrene begins in the distal part of a limb due
to ischaemia. Where the blood supply is inadequate
to keep tissue viable.
Example : Dry gangrene in the toes and feet of an
old patient due to arteriosclerosis.

5. WET GANGRENE
Wet Gangrene occurs in naturally moist
tissues and organs such as the mouth,
bowel, lung, cervix, vulva etc.
Example : Bed sores occurring in a bed-
ridden patient due to pressure on sites like
the sacrum, buttocks and heels.

6. WET GANGRENE :
Bed sores occurring in a bed-ridden patient

7. GAS GANGRENE
It is a form of wet gangrene caused by gas forming
clostridia (gram-positive anaerobic bacteria) in this
necrosis affected area is swollen, oedematous, painful
due to accumulation of gas bubbles within the tissues.
Later, foul smell comes from affected tissue and its
becomes dark black.
Gas forming clostridia gain entry into the tissues
through open contaminated wounds.
