Wound V.A.C. Therapy

How can you help hard-to-heal wounds?

Negative pressure wound therapy (NPWT) may be an option for you. This type of therapy promotes healing in acute and chronic wounds. It involves the application of negative pressure (suction) to the wound bed.

NPWT consists of a non adherent, porous wound dressing. A drainage tube is placed adjacent to or inserted into the dressing; an occlusive transparent film is used to seal the wound and the drainage tube; and a connection to a vacuum pump supplies the negative pressure.

Wound therapy is applied to an open wound for periods of 48 hours. There are two types of polyurethane foam (white and black) that is cut to shape and inserted to contact the entire wound. Black foam is more commonly for larger or deeper wounds cut to the appropriate shape of the wound and is then inserted to contact the entire wound. White foam is better used to help protect skin grafts. The foam allows for distribution of the negative pressure. Suction tubing is placed onto or in the foam, and then the entire wound/foam complex is covered with a clear plastic dressing to seal the wound. The tubing is connected to a suction pump. The drainage from the wound filter into a canister attached to the suction pump.

Positive effects:

  1. Can promote wound healing through multiple actions, includes the removal of exudates[1]
  2. Removal of slough[2], a potential decrease in wound bacterial burden
  3. A reduction in edema[3] and third-space fluids
  4. An increase in the blood flow to the wound
  5. Promotion of white cells and fibroblasts[4] within the wound
  6. Negative pressure brings tissue together, promoting caption, which allows the tissues to stick together through natural tissue adherence and increases healing
