Ultrasonic wound debridement.

• Abstract: Current management of hand injuries includes debridement by abrasive scrubbing with anti-bacterial detergents, surgical excision, or pressure irrigation. A rat model with a contaminated laceration was used to study the efficacy of ultrasonic debridement to diminish bacterial counts and particulate matter in open wounds. Ultrasonic debridement of hand wounds has several advantages over the current methods of wound debridement. These include a technically simple procedure that is effective in the removal of particulate matter and the reduction of bacterial counts (p less than 0.005). In addition there was no blood loss and no detectable damage of viable tissues as evaluated by electron microscopy. This technique may prove to be a significant advance in the early management of hand wounds.
