The exudate is absorbed by the dressing, which converts into a soft gel. The area of the dressing in direct contact with the wound itself loses its adhesiveness and thus will not damage the wound surface on removal of the dressing. Hydrocolloid dressings are also available in combination with an alginate to increase the fluid handling capability of the dressing. Indications Hydrocolloids can be used on lightly to moderately exudating wounds such as leg ulcers, pressure wounds, burns, donor sites etc. Thin hydrocolloids can also be used over suture lines and at IV sites.
Hydrocolloids are useful in the prevention of pressure areas.
The backing papers are peeled off and the dressing is applied to the wound. As the entire underside of the dressing is adhesive, there is no need for a secondary dressing. Dressings can be left in place for 3-4 days, depending on the level of exudate. Duoderm hydrocolloid dressings should be changed when the exudate seeps from the edges of the dressing or a white 'blister' appears under the dressing. Comfeel Plus hydrocolloid dressings should be changed when the dressing becomes transparent or there is any leakage.
