Negative pressure wound therapy (NPWT)

Negative pressure wound therapy (NPWT), also referred to as subatmospheric pressure wound therapy or vacuum-assisted wound therapy, is used in the treatment of slow or nonhealing wounds. NPWT involves the application of subatmospheric pressure to the open wound with the goal of creating a controlled, closed wound amenable to surgical closure, grafting, or healing by secondary intention. NPWT is thought to promote wound healing by providing a warm, moist wound bed while removing wound fluid.
