ABSTRACT
Objective:To investigate the effect of ultrasonic debridement mediated by 0.9% sodium chloride solution and 0.5% iodophor volt combined with eddy current washing and high pressure pulse washing on the removal of colonized bacteria on the wound surface of diabetic foot and wound healing.Methods:From March to November 2020, a total of 60 patients using ultrasonic therapy for debridement were divided into control group, experimental group 1, experimental group 2 and experimental group 3 by random digit table in the fourth People′s Hospital of Dalian. The final effective data collected was 15 cases in each group. The control group was given ultrasonic debridement mediated by 0.9% sodium chloride solution and eddy current washing.Experimental group 1 was given ultrasonic debridement mediated by 0.9% sodium chloride solution and high pressure pulse washing. Experimental group 2 received 0.5% iodophor mediated ultrasonic debridement and eddy current washing. Experimental group 3 0.5% iodophor mediated ultrasonic debridement and high pressure pulse washing. The size of the wound was measured, sampled and bacterial cultured before and after the first, fifth and 10th intervention. The wound bacterial clearance rate and wound area reduction rate were calculated and compared.Results:Before and after 3 interventions, the bacterial clearance rate and the total reduction of wound surface in 4 groups were increased ( P<0.01), the total bacterial clearance rate of experimental group 3 was the highest, which was (93.85 ± 9.87)%.The total reduction rate of wound in experimental group 2 was the highest, which was (20.831 4 ± 9.379 8)%. Conclusions:0.5% iodophor mediated ultrasonic debridement combined with high pressure pulse washing is the most effective way in the removal of diabetic foot wounds, and 0.5% iodophor solution mediated ultrasonic debridement combined with eddy current washing is the most effective in reducing diabetic foot wounds.
