Animal Health FAQs

  • Can you treat more than one wound with one therapy unit?

    Yes. KCI has established two methods for connecting wounds to one therapy unit: “Bridging” and “Y-connecting.” Bridging can be accomplished when you have multiple wounds of similar pathology in close proximity to one another. The V.A.C.® Drape is placed on the intact skin between wounds, and a strip of foam is placed from one wound bed to the other over the draped skin. As long as all pieces of foam are touching each other, you can place the tubing in a central location and use one pump to distribute pressure throughout all the wounds.
    Y-connecting allows you to treat multiple, non-infected wounds that are a larger distance apart by using the Y-Connector that can support two separate tubing connections. Negative pressure in either situation is distributed across the wounds, yet controlled by one pump. Please reference the V.A.C.® Therapy for Veterinary User Manual  for more information. Note: Negative pressure will be monitored at only one arm of the Y; it is not recommended for use for flaps/grafts.
  • Gauze or foam dressings. Is there a difference?

    Yes, there is a clinical difference. Although the V.A.C.® GRANUFOAM™ Dressing (black foam) may seem like simple surgical foam, it has been specifically engineered to deliver NPWT. The hydrophobic, open pore structure of V.A.C.® GRANUFOAM™ Dressings adapt to the contours of deep or irregularly shaped wounds in order to provide equal distribution of pressure at the wound site. These open pores are also manufactured under specifications to achieve a 400-600 micron pore size to help promote wound healing. Since gauze cannot provide these physical properties, it will not provide the proven benefits of V.A.C.® Therapy, and, in some cases, it may allow for the pooling of fluids, which may interfere with the wound healing process.
  • How do I know if V.A.C.® Therapy is appropriate for my patient’s wound?

    V.A.C.® Therapy is indicated for a wide range of acute and chronic wounds and is appropriate for use in all care settings. Please reference the V.A.C.® Therapy for Veterinary Use Clinical Guidelines for more information.
  • Is the V.A.C.® Therapy Dressing change a clean or sterile technique?

    The decision to use clean versus sterile/aseptic technique is dependent upon wound pathophysiology, physician/clinician preference, and institutional protocol. Dressing applications regarding clean or sterile technique are completely at the preference of the physician/clinician. Disposable components of the V.A.C.® (VACUUM ASSISTED CLOSURE™ Therapy  System), including the foam dressing (i.e., V.A.C.® GRANUFOAM™ Dressing, V.A.C.® GRANUFOAM SILVER™ Dressing, or V.A.C. WHITEFOAM™ Dressing), tubing and drape are packaged sterile and are manufactured without natural rubber latex. V.A.C.® Therapy Unit canisters are packaged sterile or fluid path sterile and are also manufactured without natural rubber latex. A clinician has the option of applying the dressings in the Operating Room utilizing a sterile/aseptic technique if needed. The clinician can also use clean technique for placement in the home setting or for pathologies that do not require sterile technique. As with all dressings that are packaged sterile, the options for use would be those in compliance with the protocols and institutional policies regarding wound care.
  • What’s the difference between the black foam and the white foam?

    The black foam — V.A.C.® GRANUFOAM™ Dressing — is hydrophobic or water repelling. The reticulated, open pore foam allows exudate to be removed and enables the dressing to conform to the wound bed providing the foam-tissue interface. This design allows for increased distribution of negative pressure across the wound bed and promotes granulation tissue formation.
    The white foam — V.A.C. WHITEFOAM™ Dressing — is hydrophilic or moisture retaining. Its higher tensile strength and less adherent properties are typically indicated for use in tunnels and shallow undermining.
