SURGICAL SITE INFECTION
From October 2018 to October 2021, a retrospective study was conducted on 55 patients hospitalized with surgical site infection after abdominal surgery. Thirty patients with SSI were treated with improved vacuum drainage sealing. Twenty-five patients with SSI were treated with vacuum drainage. In the vacuum sealing drainage group, there were 13 males and 12 females ranging in age from 46 to 79 years, with a mean of (64.09 ± 15.07) years. There were 19 males and 11 females between the ages of 47 and 84 years in the improved vacuum-sealing drainage group, with a mean age of (52.16 ± 17.54) years.
