Objective:To investigate the clinical effect of negative pressure combined with silver dressing in the infected wounds treatment.Methods:A retrospective analysis was performed on 58 patients with infectious wounds from January 2022 to January 2023,and the patients were randomly divided into the combined treatment group and control group,with 29 cases in each group.The control group was treated with traditional sterile dressing after mechanical/ultrasonic debridement,and the combined treatment group was treated with negative pressure combined with silver ion dressing based on me-chanical/ultrasonic debridement.On the 7th day of treatment,the positive rate of bacterial culture,the coverage rate of granulation tissue and the visual analogue scale(VAS)scores of the two groups were compared,and the wound healing time and the total effective rate of treatment were recorded.Results:The positive rate of bacterial culture in the combined treatment group was 10.34%(3/29),which was significantly lower than the rate of 34.48%(10/29)in the control group(P<0.05).The granulation tissue coverage rate of the combined treatment group was(86.97±3.78)%,which was significantly higher than the rate of(70.66±1.75)%in the control group(P<0.05).The wound VAS score of the combined treatment group was 1.83±0.80 points,which was significantly lower than the score of 3.76±0.95 points in the control group(P<0.05),and the wound healing time of the combined treatment group was significantly less than in the control group as(16.93±2.34)d vs(22.41±2.20)d(P<0.05).The total effective rate of the combined treatment group was 93.10%(27/29),which was significantly higher than the rate of 72.41%(21/29)in the control group(P<0.05).Conclusion:Negative pressure combined with silver dressing can effectively control wound infection,promote granulation growth,reduce pain,and shorten wound healing time.
