Wound Edge Microvascular Blood Flow

The aim of this study was to examine the effects of negative pressure wound therapy (NPWT) on wound edge microvascular blood flow, comparing different wound fillers. Wounds were created on the backs of 7 pigs. NPWT was applied, using either foam or gauze, at -50,-75, -100, -125, -150, or -175 mm Hg. Microvascular blood flow was measured in muscle tissue, subcutaneous tissue, and in the wound bed, at 0.5, 1, and 2.5 cm from the wound edge, using...
