debridement-surgical removal of foreign material and dead tissue from a wound in order to prevent infection and promote healing.
Debridement is a medical procedure in which dead, infected tissue is cut away from a wound to expose healthy living tissue. It is an important step in the treatment of many injuries, since it can be difficult to assess the severity of an injury until the dead skin has been cut away.
