Eschar
From Wikipedia, the free encyclopedia
An eschar is a scab of dead tissue covering a thermal burn, gangrene, ulcer, etc. Eschar may be allowed to slough off naturally, but it may need to be removed surgically, especially if a skin graft is to be conducted.
An escharotic is a substance that causes the tissue to die and slough off, such as acids, alkalies, carbon dioxide, metallic salts, or electric cautery.
Eschar is found in late exposure to anthrax.

Eschar is sometimes called a "black wound" because the wound is covered with thick, dry, black necrotic tissue like in third-degree burns, Stage III or IV ulcers and gangrenous ulcers. Treatment is debridement of the eschar tissue to prevent infection. If eschar is on a limb, it is important to assess peripheral pulses of the affected limb to make sure blood and lymphatic circulation is not compromised.
