Hydrocolloid dressings form an occlusive barrier over the wound while maintaining a moist wound environment and preventing bacterial contamination. A gel is formed when wound exudate comes in contact with the dressing. This gel can have fibrillolytic properties that enhance wound healing, protect against secondary infection, and insulate the wound from contaminants. [57, 130] Hydrocolloids help prevent friction and shear and may be used in stage 1, 2, 3, and some stage 4 pressure injuries with minimal exudate and no necrotic tissue.
