Wound dressings are a central component of pressure ulcer care. The selection of the dressing should be based on the tissue in the ulcer bed, the condition of the skin around the ulcer bed, and the goals of the person with the ulcer. Generally maintaining a moist ulcer bed is the ideal when the ulcer bed is clean and granulating to promote healing or closure. Several moisture-retentive dressings are available. However, the type of dressing may change over time as the ulcer heals or deteriorates. Refer to the Clinical Practice Guideline for a more complete description of all dressing types as well as a discussion of indications and contraindications for their use.
