debridement-surgical removal of foreign material and dead tissue from a wound in order to prevent infection and promote healing.
Debridement is the process of removing dead (necrotic) tissue or foreign material from and around a wound to expose healthy tissue. An open wound or ulcer can not be properly evaluated until the dead tissue or foreign matter is removed. Wounds that contain necrotic and ischemic (low oxygen content) tissue take longer to close and heal.
