What is a Hydrocolloid Dressing?

A hydrocolloid dressing is a type of advanced wound dressing made from a gel-forming material, typically a combination of gelatine, pectin, and carboxymethylcellulose, which is combined with an adhesive. The dressing is occlusive, meaning it forms a barrier to protect the wound from contaminants while maintaining a moist healing environment.

When should Hydrocolloid Dressings be used?

Hydrocolloid dressings are used for:

• Chronic Wounds: Including pressure ulcers and diabetic foot ulcers.
• Superficial Wounds: Such as minor burns, abrasions, and lacerations.
• Low to Moderate Exudate Wounds: They are particularly effective for wounds with minimal to moderate fluid production.
• Granulating Wounds: Wounds that are healing by the formation of new tissue.

They are not recommended for heavily exuding or infected wounds due to the occlusive nature of the dressing.

How do Hydrocolloid Dressings work?

Hydrocolloid dressings work by:

• Maintaining Moisture: The dressing interacts with wound exudate to form a gel, which keeps the wound moist and promotes autolytic debridement, helping to remove dead tissue.
• Protection: The dressing acts as a barrier against bacteria and other contaminants, reducing the risk of infection.
• Cushioning: It provides a cushioning effect, which can protect the wound from external pressure and friction.
