Debridement is the word used to describe a specific surgical procedure. In a debridement, the surgeon removes damaged tissue from the body to promote healing. By removing this tissue, the body is left with healthy tissue to try to speed healing. If dead, infected, or contaminated tissue is left in the body after an injury or medical condition, those tissues are likely to lead to infection.
Debridement involves the removal of necrotic tissue to promote wound healing. During wound healing, the affected area can become overrun with necrotic â or dead â tissue. This can be harmful to the bodyâs ability to recover and develop new skin, so debridement may be necessary to remove that dead material. In this way, debridement is essential for preparing the wound bed to promote speedy and efficient healing. Debridement promotes the wound healing process in a variety of ways. Not only does dead skin inhibit the development of healthy new tissue, but it makes the affected area more susceptible to infection.
