Hydrocolloid dressings

Silicone sprays and occlusives, e.g. hydrocolloid dressings, may be effective in preventing and treating pressure sores. 

In general, they consist of a pressure sensitive adhesive layer which is composed of a so-called hydrocolloid dispersed with the aid of a tackifier in an elastomer and secondly a film coating composed of a gas permeable but water impermeable, flexible, elastomeric material. A currently available hydrocolloid dressing is a flexible mass with an adherent inner face and an outer semipermeable polyurethane foam. 

Other hydrocolloid dressings with formulations consisting of sodium carboxymethylcellulose combined with karaya gum or sodium carboxymethylcellulose on its own are also available.

The treatment of plaque-tape psoriasis is the best example. Moderate clearing occurs when tapes are left in place for 2-3 weeks (Christopher et al. 1995). A variety of hydrocolloid dressings are better suited to the purpose of providing prolonged occlusion without maceration. At first glance, this outcome seems to contradict what has been the central thesis of this...

Medical use of rosin derivatives on tapes, bandages, surgical and dental dressings, wart paints (Lachapelle and Leroy 1990) and hydrocolloid dressings has been reported (Sasseville et al. 1997). For several hydrocolloid dressings, the allergen is a modified ester of colophony, the pentaerythrite ester (Hausen and Kulenkamp 1998). Most patients with a sensitisation to colophony report intolerance of brown coloured tapes. However, we have not found any report of occupational contact dermatitis to medical colophony resin adhesives.
