ObjectiveTo explore the application effects of ultrasonic debridement combined with new functional dressing in the treatment of trauma infecting wounds.

MethodsSixty-two patients with trauma infecting wounds were randomly divided into the observation group and control group according to random number table method (30 cases in observation group and 32 cases in control group).The control group was treated with the traditional treatment methods, and the observation group was treated with ultrasonic debridement combined with new functional dressing covering and dressing the wound.The pain scores at the first 3 dressing changes, wound healing time, total cost of dressing changes and scar condition after 3 months of follow-up were compared between two groups.

ResultsThe pain scores at the first 3 dressing changes in the observation group were significantly lower than that in the control group(P < 0.01).The wound healing time in the observation group was significantly shorter than that in the control group(P < 0.01), and there was no statistical significance in the total dressing change cost between two groups (P>0.05).After 3 months of follow-up, the scar score in the observation group was lower than that in the control group(P < 0.05).

ConclusionsUltrasonic debridement combined with new functional dressing in the treatment of trauma infecting wounds can reduce the pain of patients during operation, promote wound healing, reduce scar formation, and does not increase the total cost of dressing change, which is superior to the traditional dressing change method.
