Pressure ulcers are prevalent in nursing homes. They heal slowly, cause pain, impair quality of life, and are expensive to treat. Dehydration is a problem in some nursing home residents and under-perfusion a problem in others. Theoretically, providing supplemental fluid to under-hydrated residents should increase fluid in the various fluid compartments of the body, increase subcutaneous oxygen, support skin integrity, enhance pressure ulcer blood flow and pressure ulcer healing, including collagen production. This proposition has not been examined in nursing home residents with pressure ulcers.
