Hydrocolloids
Wafers, powders or pastes composed of gelatin, pectin or carboxymethylcellulose. Absorption capability depends on thickness and composition. Wafers are self-adhering and available with or without an adhesive border and in a wide variety of shapes and sizes. Useful on areas that require contouring, such as heels and sacral ulcers. Powders and pastes require a secondary dressing. Indicated for partial- and full-thickness wounds with or without necrotic tissue.
