A patient is having a surgical procedure done to relieve alteration in peripheral tissue perfusion in an extremity with full-thickness circumferential burns. What term describes this procedure?
a. Excision
b. Skin graft
c. Débridement
d. Escharotomy
ANS: D
If the patient has a circumferential burn (one that surrounds an extremity or area), an increase in tissue pressure secondary to tissue edema occurs. The burn then acts like a tourniquet, impeding arterial and venous flow. An escharotomy is immediately necessary to relieve this pressure. An escharotomy is a linear excision through the eschar to the superficial fat that allows for expansion of the skin and return of blood flow. Excision refers to cutting something out. A skin graft places new skin over a burn site. Débridement removes dead tissue.
