Negative-pressure wound therapy (NPWT) is a medical treatment that uses a vacuum dressing to enhance the healing process in acute or chronic wounds, as well as in second- and third-degree burns.

Overview[edit | edit source]

NPWT involves the application of a controlled negative pressure (vacuum) to the wound bed, which helps reduce edema, removes excess exudates, and promotes granulation tissue formation.

Indications[edit | edit source]

This therapy is particularly effective for:

Mechanism of Action[edit | edit source]

The suction provided by NPWT removes excess fluids and infectious materials from the wound. It also stimulates blood flow to the area, encouraging tissue regeneration and wound contraction.

Components[edit | edit source]

Suction Pump[edit | edit source]

The suction pump creates a controlled negative pressure environment for the wound.

Dressing Material[edit | edit source]

Specialized dressing materials are used to ensure a tight seal and effective suction around the wound area.

Procedure[edit | edit source]

The procedure for applying NPWT typically involves:

  • Cleaning the wound
  • Applying the dressing material
  • Connecting the dressing to the suction pump
  • Setting the appropriate level of negative pressure

Benefits[edit | edit source]

NPWT offers several benefits, including:

  • Faster wound healing
  • Reduced risk of infection
  • Enhanced granulation tissue formation

Risks and Complications[edit | edit source]

Although NPWT is generally safe, potential risks include:

  • Wound infection
  • Bleeding
  • Pain at the wound site

Clinical Evidence[edit | edit source]

Numerous studies and clinical trials have demonstrated the efficacy of NPWT in various wound types, underscoring its value in wound management.
