|Background: The positive influence of debridement on wound healing has been described in a number of clinical studies. To remove the necrosis, foreign material, and the damaged tissues from the surface of the wound we can use different methods and techniques. Mechanical debridement is fast and effective, but its usage is connected with many problems and disadvantages (damaging the underlying structures of the wound surface with a consequent deterioration of tissue nourishment, acute wound pain, bleeding etc.). Methods and materials: In our study, we monitored the extent of wound surface damage during the mechanical debridement on the model of a surgical wound. To remove the necrosis we used a scalpel, surgical scissors, electro-cautery and a water-jet handpiece. Tested tissue samples were sent to the coroner's office for histological analysis and assessment of the level of wound surface damage after debridement. To assess the degree of wound trauma we have created a special scoring system based on the presence of 6 microscopic markers on the tissue sample surface. This scoring system consists of three degrees of wound surface damage, indicating the range of tissue trauma. Results: We observed the smallest tissue trauma in a group treated with the hydrosurgery debridement technique. The gravest tissue trauma signs were in a group debrided with scissors. These results were validated by statistical analysis. Conclusion: Our study demonstrates that the hydrosurgery debridement method is safer than other mechanical debridement methods.
