Английская Википедия:Hydrocolloid dressing
Шаблон:Short description Шаблон:Distinguish A hydrocolloid dressing is an opaque or transparent[1] dressing for wounds. A hydrocolloid dressing is biodegradable,[2] breathable, and depending on the dressing selected, may adhere to the skin, so no separate taping is needed.[3]
The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxymethyl cellulose 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.[4]
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.[5]
Uses
Шаблон:More medical citations needed Hydrocolloid dressings are used to treat uninfected wounds.[6] Dressings may be used, under medical supervision, even where aerobic infection is present; the infection should be treated appropriately.Шаблон:Citation needed
The dressing is applied to a cleaned wound. Hydrocolloid patches are sometimes used on the face for acne. Smaller sizes are used on acne, not only to get rid of acne, but to avoid acne scars.[7] They are also used to secure nasogastric tubes or CPAP masks to the patient's face.Шаблон:Citation needed Hydrocolloid dressings are used for pressure ulcers (also known as bed sores).[8]
Effectiveness
The results of meta-analyses indicate no significant difference in healing rates between hydrocolloid dressings and other dressings (including simple dressings) for venous ulcers,[9] or for diabetic foot ulcers.[10]
There is tentative but unclear evidence for hydrocolloid dressings for superficial and partial thickness burns.[11] Hydrocolloid dressings were, however, superior to other substrates (i.e., alginate, film, gauze, hydrofiber, silicone) for treating skin graft donor sites.[12]
