How clean is clean? In-vitro comparison of biofilm removal efficacy and cleaning characteristics of three debridement pads

Abstract

AbstractObjectiveThe objective of this study was to elucidate the effectiveness of soft debridement in cleaning wounds varying in size and type of exudate and in creating/maintaining a window of opportunity for the wound to be able to heal.ApproachIn vitro comparison of cleaning characteristics (fluid holding capacity, cleaning efficacy/capacity) and biofilm removal efficacy of three different debridement pads of wounds varying in size and composition and viscosity of exudate.ResultsAll three debridement pads tested showed the ability to clean small to large wounds with different types of exudate (serous/fibrinous) as well as to remove biofilm cells to some extent. Long and dense fibres are favourable when it comes to taking up and holding onto exudate while shorter fibres help to break open harder to clean wounds.InnovationThis study presents a standardised comparison of three different debridement pads based on the defined composition of exudate and standardised cleaning protocol followed by an robotic cleaning arm. This way, the influence of the type of fibre and overall composition of the pad can be compared in a scientific manner.ConclusionA balance between fluid holding capacity and cleaning efficacy/capacity is important in order to achieve the best overall results and successfully remove exudate as well as biofilm cells from small to large wounds with different types of exudate. This in turn has a potential influence on the microenvironment of the wound.
