Silver from Polyurethane Dressing Is Delivered by Gradient to Exudate, Tissue, and Serum of Patients Undergoing Negative-Pressure Wound Treatment

Abstract

The high concentration of silver found in wound exudate reflects not only the affinity for silver in serum components and wound fluids, but also that most silver ions are not distributed systemically in the patient; instead, they are transported by the vacuum created by therapy.
