Which dressing is commonly used to protect periwound skin while providing a moist environment?

• A. Foams
• B. Gauze
• C. Transparent film
• D. Hydrocolloid

Answer: (D)

Maintaining a moist wound environment while protecting the skin around the wound is best achieved with hydrocolloid dressings. These dressings are semi-occlusive and interact with wound exudate to form a soft gel, which keeps moisture at the wound surface. That moist environment supports epithelial migration and healing, while the dressing also acts as a protective barrier that cushions and shields the periwound skin from friction and maceration. They tend to adhere to the surrounding healthy skin rather than the wound bed, making removal gentler on delicate periwound tissue.

Other dressings don’t hit both needs as effectively. Foams focus on absorbing drainage and cushioning but aren’t as consistent at sustaining a stable moist microclimate around the wound. Gauze can dry out the area or stick to tissue, risking damage when removed. Transparent films provide a moisture barrier and allow visualization, but they are less reliable for absorbing exudate and can trap fluid, potentially leading to maceration if there’s significant drainage.
