Which practice is NOT recommended for wound cleaning?

• A. Clean with room-temperature water
• B. Use hydrogen peroxide
• C. Avoid scrubbing
• D. Do not use harsh chemicals

Answer: (B)

Cleaning a wound should remove debris without injuring healing tissue. Hydrogen peroxide is not recommended because its bubbling action and release of oxygen can damage healthy cells like fibroblasts and keratinocytes that are essential for healing. This cytotoxic effect can delay healing and epithelialization when used repeatedly on a wound. The safer approach is to rinse with clean, room-temperature water or sterile saline, avoid scrubbing, and steer clear of harsh chemicals. If needed, mild soap around the wound edge can be used, but the goal is gentle cleansing without tissue-damaging agents.
