title: Cytotoxicity testing of burn wound dressings: first results.
abstract: Topical antimicrobial therapy represents an essential part of burn wound care. In order to prevent and treat burn wound infection dressings with antimicrobial properties are applied directly on the wound surface. Not only the infection control but also promotion of healing is very important in burn wound management. It is well known, that a dressing in bactericidal concentration might also delay wound healing. This study was aimed to evaluate the potential toxic effect of topical antimicrobial agents on murine and human dermal cells. For toxicity testing the method by Vittekova et al. was used to evaluate potential toxic effects of 16 agents and 6 control samples on two in vitro cultured cell systems [3T3 cells and dermal fibroblasts] during the first 24 h. Following the 24 h cell culture with the tested agents the live cell counts were evaluated. According to results obtained on both cell systems, the tested samples were divided into three groups-nontoxic, semi-toxic and toxic. Nontoxic samples included Acetic acid 1%, Acticoat®, Dermacyn®, Framykoin®, Silverlon®, gauze, acellular human allodermis and acellular porcine xenodermis. Semi-toxic group included Algivon®Plus, Aquacel®Ag, Betadine®, Nitrofurazone, Octenisept®, Suprasorb®A and a porcine dermal scaffold Xeno-Impl. Finally, the toxic group included Algivon®, Dermazin®, Ialugen®Plus, Prontoderm®, Suprasorb®A Ag and 20% SDS. As the preliminary results of this study have shown, our findings may serve as a potential guide to selection of the most appropriate topical antimicrobial dressings for treatmet of burns. However before they can be translated into clinical practice recommendations, more research on antimicrobial dressings cytotoxicity testing will be necessary.
