Negative Pressure Wound Therapy

Negative Wound Pressure Therapy

Wound therapy can often be both expensive and difficult for the patient.  Recent developments in Negative Pressure Wound Therapy or “Wound-vacs” have provided an alternative solution for the patient that can be very effective and cost-efficient.  Many different types of wounds, either chronic or acute, can now be treated utilizing this therapy.  You can even use this breakthrough technology in the comfort of your own home.

Negative Pressure Wound Therapy can help people heal faster, discharge from the hospital sooner, and thereby save healthcare costs.

What Is Negative Pressure Wound Therapy?

A therapeutic technique using a vacuum dressing to promote healing in acute or chronic wounds. Therapy is performed by applying controlled sub-atmospheric pressure evenly to the local wound environment, using a sealed wound dressing connected to a vacuum pump.

Who Is A Candidate For Negative Pressure Wound Therapy?

Candidates for negative pressure wound therapy include individuals suffering from:

  • Chronic ulcers caused by unrelieved pressure (bedsores), diabetes mellitus, venous insufficiency or arterial insufficiency
  • Wounds with copious drainage
  • Chronic wounds that have not responded to other treatments
  • Acute or surgical wounds at high risk for infection

Negative pressure wound therapy can be used on wounds such as: open fractures, infected wounds, skin grafts, pressure ulcers and more.

When Is Negative Pressure Wound Therapy No Longer Necessary?

The best sign of treatment completion is when there are no clinical signs of active infection at the wound site. Your doctor will work with you to determine the most successful treatment plan. Any questions about discontinuing Negative Pressure Wound Therapy treatment should be discussed with your physician.

How Does A Negative Wound Pressure Therapy Machine Work?

Foam dressings apply mechanical forces to the wound to create an environment that promotes wound healing. These forces are known as macrostrain and microstrain.

Macrostrain is the visible stretch that occurs when negative pressure contracts the foam. It draws wound edges together, provides direct and complete wound bed contact, evenly distributes negative pressure, and removes infectious substances.

Microstrain is the microdeformation at the cellular level, which leads to cell stretch. It reduces edema, promotes perfusion, and promotes granulation tissue formation by facilitating cell migration and proliferation.
