Pressure ulcers are skin and soft tissue lesions appearing in over-pressured places of the body. According to EPUAP/ NPUAP classification, the presence of necrosis is a basic condition for determining the third and fourth stage of pressure ulcers. Necrotic tissue on the wound impedes the healing process and granulation tissue formation and is a source of infection and malodour. It poses a serious wound bioburden. Removal of the necrosis (necrectomy) and pressure ulcer bed debridement are important steps in a wound bed preparation (TIME concept). In practice, presence of moist necrosis (slough) is often being connected with presence of a wound infection, whereas dry gangrene (eschar) obstructs wound healing far less, and non-infected eschar can in some cases serve as a temporary pressure ulcer covering. Proper timing of debridement together with selectionof a correct debridement method noticeably affects treatment results. Despite of the well-known advantages, debridement can sometimes disrupt the healing process: over-excision leads to removal of the necrosis and even of the vital tissue close to the necrosis; debridement methods causing wound trauma (scissors, electrocautery) remove deficient tissues as well as they disrupt the wound bed vitality. Our research consisted of two parts: experimental (on a tissue model) and clinical part (on a group of probands). We have shown that sharp (scalpel) and hydrosurgical debridement (Vestajet) speed up the debridement process and shorten the total time for tissue recovery.

Key words:
debridement – pressure ulcer – necrectomy
