Abstract: Objective：To explore the value of ultrasonic debridement combined with moist therapy in the treatment of diabetic foot ulcer.Methods：68 patients with diabetic foot ulcer in our hospital from January 2019 to January 2020 were randomly divided into two groups:the observation group and the control group，there were 34 cases in each group.Ultrasound debridement combined with moist therapy was the observation group,and traditional debridement combined with moist therapy was the control group,34 cases in each group.The wound healing,local tissue perfusion,wound healing time and dressing change times of diabetic foot ulcer in the two groups were recorded and analyzed statistically.Results：The wound healing of the observation group was better than that of the control group on the 7th and 14th day after the first treatment(33.13±3.05 vs.35.19±3.82,P<0.05;21.58±3.63 vs.28.22±4.75,P<0.05).On the 14th day after the first treatment,the local blood perfusion in the observation group was significantly better than that in the control group[(1.21±0.19 )PU vs.(0.83±0.15）PU,P<0.05].The number of dressing changes and healing time in the observation group were significantly shorter than those in the control group[12.61±1.44 vs.20.44±2.40,P<0.05;(21.29±2.84)d vs.(30.88±3.28)d,P<0.05].Conclusion：Ultrasonic debridement combined with moist therapy has obvious advantages over traditional debridement combined with moist therapy in the treatment of diabetic foot ulcer wounds.
