Introduction

In recent years, a range of wound care courses, study days, and conferences have been developed in an attempt to update health care professionals about advances in wound management. One of the knowledge and skills that have to be acquired are the techniques of the debridement. Debridement is an important element of the wound bed preparation paradigm [1] and describes any method by which devitalized tissues/necrosis are removed [2]. In addition, tissue necrosis in the wound bed serves as an area ideal for bacterial overgrowth and infection; it can contribute to protein losses in wound exudate and often delays healing [3]. They also form a barrier to prevent angiogenesis, the formation of granulation tissue or the extracellular matrix, as well as the re-epithelialization [4]. Necrotic tissue may inhibit the direct contact of agents applied in the wound bed and hamper the clinician from making a proper assessment, for example, in masking a possible underlying infection [2]. There is a growing body of evidence and agreement among wound clinicians and scientists that debridement represents a necessary process in reducing bacteria, infection, and a biofilm within a wound and promotes a stimulatory environment for healing [5].
