Debridement: an essential component of traumatic wound care

Abstract

The harmful influences of devitalized tissue on wound defenses are documented and the importance of wound debridement in the care of the traumatic wound is stressed. All devitalized soft tissues damaged the host's defenses and encouraged the development of infection. The capacity of divitalized muscle, fat, and skin to enhance infection was comparable. The infection-potentiating effect of skin was enhanced by exposing it to a dry thermal injury. The mechanisms by which devitalized soft tissue enhanced infection are several. The devitalized soft tissue acts as a culture medium promoting bacterial growth. In addition, the devitalized tissue inhibits leukocyte phagocytosis of bacteria and subsequent kill. Finally, the anaerobic environment within the devitalized tissue may also limit leukocyte function.
