Modified wound negative pressure suction technology combined with silver nanoparticle dressings in elderly chronic wound care

OBJECTIVES: The aim of this study was to evaluate the clinical efficacy of modified wound negative pressure suction technology combined with nano-silver dressings in the management and care of chronic wounds in elderly patients. METHODS: 101 elderly patients with chronic wounds admitted to hospital between January 2023 and December 2023 were selected as research subjects. Patients were divided into control (50 cases: routine dressing changes) and treated groups (51 cases: modified wound negative pressure suction technology combined with nano-silver dressings). The wound bed score (WBS) and visual analogue score (VAS) of each group at different time points were collected, as well as relevant wound characteristics data, to compare therapeutic effects. RESULTS: Both groups completed the expected treatment and follow-up period, and there were no significant differences in the baseline data before treatment (P > 0.05). Before treatment, the WBS score of the treated group (6.53±2.75) was lower than that of the control group (8.06±2.05), and the VAS score of the treated group (4.55±2.38) was higher than that of the control group (3.42±0.79), albeit not statistically significant (P > 0.05). After the stipulated treatment period, the WBS score of the treated group (11.94±2.03) was significantly higher than that of the control group (10.84±1.91, P < 0.001, and the VAS score of the treated group (1.92±0.75) was significantly lower than that of the control group (0.75±0.72, P < 0.001. The number of dressing changes, exudate reduction time, pain onset time, hospital stay, and dressing satisfaction of the treated group were significantly better than those of the control group (P < 0.5). In addition, the positive rate of bacteria was decreased, the wound healing rate was increased, and the healing time was shortened (P < 0.05). CONCLUSIONS: Modified wound negative pressure suction technology combined with nano-silver dressings is effective for the treatment of elderly chronic wounds.
