How should a pressure sore be kept clean?

Frequent rinsing. Pressure sores are perfect areas for bacteria to colonize, inhibiting wound healing. With each dressing change, which should be at least twice a day, one should gently rinse off the wound base with either salt water or gentle soap and water, followed by application of silvadene (silver sulfadiazine) to prevent infection.
Clean and moist. Twce a day cleansing with a mild soap, such as castille or cetaphil and after soilage is recommended followed by a moist dressing. Clean non-infected wounds can be treated with vac therapy. Surgery may be necessary.
