Immediate skin grafting of sub-acute and chronic wounds debrided by hydrosurgery

A wound bed may be prepared by various non-surgical debridements using autolytic, biological or enzymatic techniques. These are all effective in selective wounds but tend to be time consuming. Surgical debridement is not selective since healthy collateral tissue is also removed. Physical debridement uses whirlpool therapy to slough off necrotic tissues e the saline which comes out of the hand piece if vapourised over the wound e and therefore disseminates contaminated droplets. Hydrosurgery combines physical and surgical debridement but does not have their drawbacks. Water dissection works by using a high-pressure jet of sterile saline that travels parallel to the wound and creates a Venturi effect, thus enabling the selective removal of necrotic tissues without dissemination of contaminants. In this study, the authors report on 167 sub-acute and chronic wounds from 155 patients treated under general anaesthesia by hydrosurgery (Versajet(R)). Of these, 95% of the debrided wounds were immediately covered with an autologous meshed graft. Compared to other debridement techniques, hydrosurgery has two main advantages: namely its tissue selectivity and its high percentage of successful engraftment after immediate skin grafting.
