What is Gangrene?O 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.

O Fingers, toes, and limbs are most often affected, but gangrene can also occur inside the body, damaging organs and muscles.

Symptoms of GangreneO Persistent feverO Skin changes — including

discoloration, warmth, swelling, blisters or lesions — that won't go away

O A foul-smelling discharge leaking from a sore

O Sudden pain at the site of a recent surgery or trauma

O Skin that's pale, hard, cold and numb

Types of GangreneO Dry gangreneO Wet gangreneO Gas gangreneO Necrotising fasciitisO Internal gangreneO Fournier’s gangreneO Meleney's synergistic gangrene

CausesO Gangrene happens when a body part loses

its blood supply. This may happen from injury, an infection, or other causes.

O •A serious injuryO •Blood vessel disease (such as

arteriosclerosis, also called hardening of the arteries, in your arms or legs)

O •DiabetesO •Suppressed immune system (for example,

from HIV or chemotherapy)O •Surgery

PreventionO Gangrene may be prevented if it is

treated before the tissue damage is irreversible. Wounds should be treated properly and watched carefully for signs of infection (such as spreading redness, swelling, or drainage) or failure to heal.

Exams and TestO Arteriogram (special x-ray to see any

blockages in the blood vessels) to help plan treatment for blood vessel disease

O Blood tests (white blood cell count may be high)

O CT scan to examine internal organsO Culture of the tissue or fluid from wounds to

identify bacterial infectionO Examining tissue under the microscope to

look for cell deathO X-rays

TreatmentsO Treatment for gangrene involves

removing the dead tissue, treating and preventing the spread of infection, and treating the condition that caused gangrene to develop. The sooner you receive treatment, the better your chance of recovery.
