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. For these reasons, gauze will not provide the proven benefits of NPWT, and, in some cases, the pooling of fluids may occur and interfere with the wound healing process.
