Traumatizace rány při chirurgickém débridementu – experimentální studie

Overview

Surgical debridement is included in many guidelines and clinical standards. The meaning of surgical debridement is to remove necrotic parts of tissue, coatings, foreign bodies, stuck remains of dressings and senescent cells without any ability to reproduce. We can assume different techniques of surgical debridement bring about different grade of local tissue trauma. This experiment is objectifying the soft tissue trauma degree on experimental wound model during sharp debridement procedure and comparing the tissue sample trauma degrees (n=128). We tested debridement realized by surgical scissors, scalpel, electrocautery and hydrosurgery (Versajet device). The analysis of the obtained experimental data gave appealing information hydrosurgery method has reconcilable lower levels of wound surface damage and clinical efficiency related to wound healing than scissors and electrocauthery (p=0.00013, p=0.00145). There was no difference (p=0.17775 ) in tissue trauma degree spread between scalpel and hydrosurgery. Surgical scissors cause more serious wound bed trauma, they are unselective and increase the incidence of secondary necrosis at the wound bed.
