All About of Negative Pressure Wound Therapy

Negative Pressure Wound Therapy, NPWT, or vacuum-assisted closure (VAC) is a wound healing technique used to expedite the wound healing process. Wound care techniques have grown throughout the ages, advancing over time in terms of technology, medical knowledge, and expertise so that wound healing can be precise, faster, and healthier than before. NPWT is one such technique that began gaining prominence during the turn of the 20th century and has now become a part of wound care around the world.

What is Negative Pressure Wound Therapy?

Negative pressure wound therapy or NPWT is a wound care technique that involves the use of negative or sub-atmospheric pressure to the local wound environment to speed up the healing process. A sealed wound dressing is used over the wound which is then connected to a tubing and a suction pump that continuously or intermittently apply negative pressure to the wound to draw fluids out from the wound and increase blood circulation at the wound bed. Depending on what type of wound is being cared for, we can vary the amount of pressure and the number of times and duration it is applied for.

How Does Negative Pressure Wound Therapy Work?

Apply negative pressure wound therapy to the wound involves three major steps. They are:

  • Dressing the wound – A foam or gauze dressing is first applied over the wound, gently but firmly. A secondary dressing or filter is then applied on top of the foam or gauze dressing which is sealed tight so that no air can enter or escape from the dressing. An overlay of transparent film is then finally applied to the wound to provide a final seal of protection. One can use different types of dressings such as foam, gauze, non-adherent, or contact layer dressings as the primary dressing. Ensure that the wound is filled properly and the secondary dressing is secure.
  • Attaching the tubing – The second step is to attach the tubing to the wound. The tubing is securely inserted into the dressing and is sealed with care to avoid any leaks or damages to the dressing. Leaks or damages to the dressing can render the therapy useless, and so it is important to make sure the tubing is attached properly. Incorrect attachment to the wound dressing can also damage the wound at times.
  • Applying the vacuum – The tubing is then connected to a vacuum pump that is set to deliver continuous or intermittent negative pressure to the wound to initiate NPWT. Depending on the type of wound, the pressure is adjusted. The goal of the negative pressure wound therapy is also important in deciding the amount of pressure that has to be applied as well as the duration of the therapy.

What Type of Wounds Benefit from NPWT?

There are a wide range of wounds that can benefit from negative pressure wound therapy, but the major wound types that benefit the most from NPWT include:

  • Open Surgical wounds
  • Closed Surgical wounds
  • Pressure ulcers
  • Diabetic foot ulcers
  • Skin grafts
  • Laparotomy
  • Venous insufficiency ulcers
  • Heavily exuding wounds
  • Heavily granulating wounds
  • Acute traumatic wounds
  • Chronic open wounds
  • Dehisced incisions

What are the Benefits of Negative Pressure Wound Therapy?

Negative Pressure Wound Therapy began as a simple technique to remove excess exudate but the technological advancements of NPWT have enhanced the process of wound healing over the years. The benefits of NPWT include:

  • Optimized blood flow to the wound bed
  • Decrease in local tissue inflammation thus reducing pain and irritation
  • Removal of excessive fluid which usually slows cell growth and proliferation in the wound bed
  • Creates an anti-bacterial environment at the wound to reduce chances of infections
  • Reduces hospital stay duration as it helps heal the wound faster
  • Reduces orthopaedic trauma and pain from open fractures
  • Better wound healing for patients with diabetes and gangrene

What are the Complications Associated with NPWT?

There are a few complications associated with negative pressure wound therapy, which can be avoided with the right kind of care and expertise. They include:

  • Pressure necrosis
  • Growth of granulation tissue into the dressing
  • Increased pain during the first few phases of therapy
  • Contact dermatitis due to the transparent taping
  • Injury to the skin around the wound
