title: Clinical experience with wound biofilm and management: a case series.
abstract: Biofilm is a relatively new concept in the fields of infectious disease, wound infection, and healing. Although scientific research and "noise" regarding wound biofilm is increasing, little is known about the presentation, diagnosis, potential implications, and management strategies regarding wound biofilms. A series of four clinical cases is utilized to demonstrate the existence of wound biofilm. All patients presented with or developed a film on the wound bed that appeared to be distinct from slough; wounds also were failing to progress. Although the slough in some of the wounds was easily removed with traditional debridement methods, removal of the film required physical disruption with a curette or dry gauze. All wounds eventually progressed to healing. Considering the biofilm concept and available preclinical research, it is evident from this small case series that the appearance of biofilm in wounds is quite different from slough and requires different management strategies for its control. The evolving biofilm paradigm could profoundly change approaches to wound management. Additional research is needed in this evolving aspect of wound management.
