An escharotomy is a surgical procedure performed to allow greater
circulation to a part of the body. A severe injury, such as a burn, can
cause skin and tissue to swell so much that blood no longer flows
easily past the injury. For example, a severe burn on the upper arm
can cause the skin and tissue to become so tight that the hand does not
get the blood flow it should. To prevent damage to the tissues
that are not getting enough blood, surgical incisions are made along the
damaged area, which releases the pressure of the swollen tissues and
allows blood flow to resume. Because of the swelling of the damaged
tissue, the surgical incisions may spread open, showing the tissues and
structures beneath the skin. Any open wound has a risk of infection so the area may be covered in sterile bandages.
