The purpose of this study was to assess the potential differences in antibacterial activity and fluid flow rates Of 2 commonly used silver dressings: an alginate-only dressing and an alginate dressing with a nonadherent contact layer. Materials and Methods. The dressings' antibacterial activities were tested against 2 major bacterial pathogens for skin wounds Staphylococcus aureus and Pseudomonas aeruginosa using 2 in vitro models of skin wounds. The fluid flow rate through the 2 dressings was also measured and compared. Results. While materially similar, the choice to include a nonadherent layer leads to reduced antibacterial performance and a reduced rate of fluid flow into and through the dressing. Conclusion. The use of the silver antimicrobial alginate dressing with a nonadherent layer provides a welcome feature in that it does not adhere to surfaces; however, the results demonstrate lower rate Of fluid removal when compared to a silver antimicrobial alginate without the nonadherent layer.
