Background

  • Negative Pressure Wound Therapy (NPWT), also known as a wound vac, is a technique for treating acute and chronic wounds by using a sealed wound dressing attached to a vacuum pump.
  • The vacuum creates a negative pressure gradient that draws out fluid and increases blood flow to the area.
  • Often applied to wounds that are expected to heal poorly, such as diabetic foot ulcers, pressure ulcers, or very large tissue defects.

Contraindications

  • Malignancy in the wound
  • Untreated osteomyelitis
  • Non-enteric or unexplored fistulas
  • Presence of an eschar
  • Direct exposure of blood vessels, anastamoses, internal organs, or nerves.

Efficacy

  • High quality evidence exists for improved outcomes in the treatment of diabetic foot ulcers.
  • Poor quality or insufficient evidence suggests NPWT may improve treatment of bedsores, large tissue defects, or other wounds.
  • There is little evidence to suggest an increased risk of complications, so wound vacs are often applied to many other kinds of wounds.
