the Benefits of Hydrocolloid dressings

What is a Hyrocolloid dressing?

A hydrocolloid dressing such as Duoderm,[1] and 3M Tegaderm Hydrocolloid is an opaque dressing. A hydrocolloid dressing is biodegradeable, non breathable and adheres to the skin as a result no separate taping is required
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 cont…
act with wound exudate, the polysaccharides and other polymers absorb water and swell, forming a gel which is held within the structure of the adhesive matrix. The moist conditions produced under the dressing are intended to promote fibrinolysis,angiogenesis and wound healing, without causing softening and breaking down of tissue. What is Controlled Gel formula? The gel which is formed as a result of the absorption of wound exudate is not mobile and free running but held within the structure of the adhesive matrix. Most hydrocolloid dressings are waterproof, allowing normal washing and bathing.[2] Dressings may be used, under medical supervision, even where aerobic infection is present; the infection should be treated appropriately.
Generally a Hydrocolloid dressing is applied to a cleaned wound. Hydrocolloid patches are sometimes used on the face for acne. They are also used to secure nasogastric tubesor 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 to against scratching.

What are the main indications for hydrocolloid dressings?
Hydrocolloids are easy to use, require changing only every 3-5 days, and do not cause trauma on removal. This makes them useful for clean, granulating, superficial wounds, with low to medium exudate.
Hydrocolloids provide effective occlusion; with dry wounds, they can have a softening effect, and they have been used to prevent the spread of MRSA (by providing a physical occlusive barrier)
The risk of complications when using hydrocolloids is very low, but some patients experience allergic reactions. If a wound becomes painful or a skin rash develops around the site of the hydrocolloid dressing, it should be removed immediately and reported to a doctor. The physician can determine if a different type of dressing needs to be used.
