Silver ‐based wound dressings reduce bacterial burden and promote wound healing

This study investigated the potential of three silver‐containing dressings, namely KoCarbonAg®, Aquacel® Ag and Acticoat 7, in reducing bacterial survival and promoting wound healing. The ability of these dressings to block the entry of bacteria from external environment and retain intrinsic bacteria was studied in vitro. In addition, the study used a rat model to compare the healing efficiencies of the three dressings and investigate the quantity of collagen synthesis in vivo. In vitro results indicated that the silver‐containing dressings prevented bacterial growth in wounds by blocking the entry of external bacteria and by retaining the bacteria in the dressing. In vivo study indicated that reduction in bacterial burden accelerated wound healing. Wounds treated by the silver‐containing dressings showed better healing than those treated with gauze. Moreover, KoCarbonAg® further accelerated wound healing by promoting collagen synthesis and arrangement.
