Debridement of skin/tissue (first 20 sq cm) Dermatology Surgery
Debridement removes dead, damaged, or infected skin and soft tissue from a wound so healthier tissue can grow.
Overview
Debridement removes dead, damaged, or infected skin and soft tissue from a wound so healthier tissue can grow. The goal is to reduce bacteria, control odor and drainage, and help the wound heal. The phrase "first 20 sq cm" describes the size of tissue treated in one session. Larger areas may be treated in sections. Debridement can be done in a clinic, at the bedside, an outpatient center, or an operating room depending on the wound and method.
Also known as: Wound debridement, Skin debridement, Sharp debridement, Selective debridement
