2. 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.

3. Symptoms of Gangrene O Persistent fever O 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

4. Types of Gangrene O Dry gangrene O Wet gangrene O Gas gangrene O Necrotising fasciitis O Internal gangrene O Fournier’s gangrene O Meleney's synergistic gangrene

5. Causes O Gangrene happens when a body part loses its blood supply. This may happen from injury, an infection, or other causes. O A serious injury O Blood vessel disease (such as arteriosclerosis, also called hardening of the arteries, in your arms or legs) O Diabetes O Suppressed immune system (for example, from HIV or chemotherapy) O Surgery

6. Prevention O 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.

7. Exams and Test O 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 organs O Culture of the tissue or fluid from wounds to identify bacterial infection O Examining tissue under the microscope to look for cell death O X-rays

8. Treatments O 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.
