Effect of combining nano-silver dressing and vacuum sealing drainage with negative pressure treatment on patients with diabetic foot ulcers

This study investigates the efficiency of the combination of nano-silver dressing and vacuum sealing drainage (VSD) with negative pressure treatment on healing diabetic foot ulcers (DFU). A total of 100 patients with DFU admitted to our hospital between January 2022 and February 2023 were selected and randomly divided into a control group and an observation group, each consisting of 50 cases. Both groups received nano-silver dressings after debridement, but the observation group also underwent closed negative pressure drainage. Scores for wound granulation morphology and comfort were assessed before and after treatment. Efficacy rate, healing time, and clinical outcomes were evaluated before and after treatment. Serum levels of procalcitonin (PCT), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and cystatin C were measured before treatment and 30 days into treatment. After 10 days of treatment, the observation group showed a higher effective rate (96%) compared to the control group (88%). The observation group had better wound granulation morphology and comfort scores, shorter granulation and healing times, reduced hospitalization duration, and smaller wound areas than the control group. Both groups experienced decreased levels of IL-6, PCT, hs-CRP, and cystatin C after treatment. The observation group had lower levels of these markers compared to the control group. In conclusion, the combination of nano-silver dressing and VSD with negative pressure treatment improves the clinical efficacy of treating DFU. This approach reduces inflammation and promotes wound healing, as evidenced by improved wound scores, faster healing times, and reduced inflammatory marker levels.
