To analyze the application effect of vacuum sealing drainage (VSD) combined with silver ion dressing on chronic refractory wound repair in elderly patients.

A total of 62 elderly patients with chronic refractory wounds who were admitted to Zhengzhou Ninth People’s Hospital from January 2015 to March 2021, aged 61 to 75 years, were divided into two groups according to the treatment plan. Thirty-one cases in the conventional group were treated with conventional treatment, and 31 cases in the combined group were treated with VSD combined with silver ion dressing. The curative efficacy, recovery indicators, wound area improvement rate, granulation maturity, lactate dehydrogenase (LDH), and C-reactive protein (CRP) were compared between the two groups.

The total effective rate in the combined group was 96.77% (30/31), which was higher than 70.97% (22/31) in the conventional group, P<0.05. The granulation growth time, wound healing time and hospital stay in the combined group were shorter than those in the conventional group (t=17.100, 12.098, 19.025, P<0.05). At 3, 7, and 21 days after treatment, the wound area improvement rate in the combined group was higher than that in the conventional group (t=4.746, 12.606, 18.966, P<0.05). The proportion of granulation maturity Ⅳ degree in the combined group was higher than that in the conventional group (U=2.357, P=0.018). After treatment, the LDH and CRP in the combined group were lower than those in the conventional group (t=8.686, 18.548, P<0.05).

The application of VSD combined with silver ion dressing in the repair of chronic refractory wounds in the elderly patients has a good effect. It can improve tissue hypoxia and inflammatory state, increase granulation maturity, and accelerate wound recovery.
