The nurse is providing care to a patient with a third-degree burn on the left thigh and left forearm. During wound care, the nurse applies Elase to the burned areas. Which type of wound debridement is this nurse using?
1. enzymatic
2. mechanical
3. surgical
4. topical
Correct Answer: 1
Enzymatic debridement involves the use of a topical agent to dissolve and remove necrotic tissue. An enzyme such as Elase is applied in a thin layer directly to the wound and covered with one layer of fine mesh gauze. A topical antimicrobial agent is then applied and covered with a bulky wet dressing. Mechanical debridement may be performed by applying and removing gauze dressings, hydrotherapy, irrigation, or using scissors and tweezers. Surgical debridement is the process of excising the wound to the fascia or removing thin slices of the burn to the level of viable tissue. Topical treatments are key in the care of a burn but do not involve debridement.
