Negative Pressure Wound Therapy

Over the span of a century, researchers and clinicians have described improved wound healing with adjunctive NPWT. In practice, the benefits and goals of removing excessive exudate from purulent wounds through vacuum assisted drainage have grown to include:

  • Reduction of painful dressing changes
  • Increased blood flow
  • Maintenance of a moist wound environment
  • Removal of third-space fluids and debris
  • Establishment of fluid balance
  • Reduction of edema
  • Increased growth factors
  • Positive effects on leukocytes and fibroblasts
  • Removal of slough
  • Improved wound stability
  • Prevention of maceration

Recent research and expanding clinical experience aim to more fully explain the underlying mechanisms by which NPWT confers its benefits, and to optimize treatment protocols. In general, there is increased dialogue among wound care specialists about:

  • The use of lower negative pressure settings in general than traditionally applied
  • The use of different pressure recommendations for different types of tissue
  • The potential benefits of using variable pressure therapy and intermittent pressure therapy protocols versus continuous therapy
