Negative Pressure Wound Therapy (NPWT) is a topical treatment used to promote healing in acute and chronic wounds. It involves the application of negative pressure (suction) to the wound bed. The concept is to turn an open wound into a controlled, closed wound while removing the excess fluid from the wound bed, thus enhancing circulation and disposal of cellular waste from the lymphatic system. (1) NPWT consists of a nonadherent, porous wound dressing; a drainage tube placed adjacent to or inserted into the dressing; an occlusive transparent film used to seal the wound and the drainage tube; and a connection to a vacuum pump that supplies the negative pressure. This technique is usually considered only for chronic, acute, and difficult-to-heal wounds. The common applications for NPWT appear in the table (see p. 60). (1)

The use of negative pressure to promote healing of open wounds has a proven track record for efficacy and ease of use. This article discusses how NPWT works and reviews the documented benefits of this therapy. Two case studies are presented that demonstrate NPWT's efficacy.

The American Medical Directors Association crafts guidelines specifically for long-term care

Pressure ulcers are serious problems not only for nursing home residents, but for the long-term care industry, as well. In today's litigious climate, nursing homes must take steps to ensure that their wound management programs quickly identify, treat and, preferably, prevent pressure ulcers. To help them devise programs that are best for both residents and the industry, the American Medical Directors Association (AMDA) offers the Pressure Ulcer Therapy Companion.
