How is enzymatic debridement performed?

1. Using surgical instruments for precise cuts

2. Collagenase is applied to the wound

3. By keeping the area dry to promote healing

4. Through aggressive scrubbing of the wound

The correct answer is: Collagenase is applied to the wound

Enzymatic debridement is a process that involves the application of specific enzymes to facilitate the breakdown of necrotic or devitalized tissue in a wound. Collagenase, which is an enzyme that specifically breaks down collagen, is commonly applied to the wound to target and digest the dead tissue without harming the surrounding healthy tissue. This selective process promotes the healing of the wound by preparing a clean base for further healing interventions. In contrast, using surgical instruments for precise cuts refers to surgical debridement, which is more invasive and typically performed in an operating room. Keeping the area dry is not relevant to enzymatic debridement, as moist environments are often preferred for wound healing. Aggressive scrubbing may damage tissues and should not be used in the context of wound care as it can lead to further complications rather than promoting healing. Therefore, the application of collagenase represents the essential mechanism of enzymatic debridement effectively.
