A hydrocolloid dressing is an opaque or transparent[1] dressing for wounds. A hydrocolloid dressing is biodegradeable, non-breathable, and adheres to the skin, so no separate taping is needed.

Trade names include Exuderm, Comfeel Plus, Duoderm, Granuflex, Ultec, and 3M Tegaderm Hydrocolloid.

The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxy-methylcellulose together with other polymers and adhesives forming a flexible wafer. In contact with wound exudate, the polysaccharides and other polymers absorb water and swell, forming a gel. The gel may be designed to drain, or to remain within the structure of the adhesive matrix.[2]

The moist conditions produced under the dressing are intended to promote fibrinolysis, angiogenesis and wound healing, without causing softening and breaking down of tissue. The gel which is formed as a result of the absorption of wound exudate is held in place within the structure of the adhesive matrix. Most hydrocolloid dressings are waterproof, allowing normal washing and bathing.[3]

Uses[edit]

Hydrocolloid dressing are used to treat uninfected wounds.[4] Dressings may be used, under medical supervision, even where aerobic infection is present; the infection should be treated appropriately.

The dressing is applied to a cleaned wound. Hydrocolloid patches are sometimes used on the face for acne. They are also used to secure nasogastric tubes or CPAP masks to the patient's face. Hydrocolloid dressings are used for pressure ulcers (also known as bed sores). They are used in the treatment of eczema, to seal steroid ointment underneath and to provide a barrier against scratching.

Other Uses[edit]

There are also acne size to get rid of acne and avoid acne scars. Trade names: 3M, Miacare, Nexcare, Dots Pro canada, Dream dots, Cover-Dot Acne Care.

Effectiveness[edit]

The results of meta-analyses indicate no significant difference in healing rates between hydrocolloid dressings and other dressings (including simple dressings) for venous ulcers,[5] or for diabetic foot ulcers.[6][needs update]

There is tentative but unclear evidence for hydrocolloid dressings for superficial and partial thickness burns.[7]
