One of the most important principles of proper wound bed preparation is certainly wound cleansing, as only a clean wound can heal rapidly and without complications. A vital tissue such as necrosis and fibrin coating, detritus and a high bacterial load can considerably affect wound healing, resulting in stagnation of the wound healing process, the so-called “chronic” or “non-healing” wound. Only a clean wound can heal; consistent cleansing of a wound, combined with the correct application of wound coverings, leads to the successful wound healing that one expects.
