ROLE OF NEGATIVE PRESSURE WOUND THERAPY IN PREVENTION OF SURGICAL SITE INFECTION IN COLORECTAL SURGERY

We try to demonstrate the reduction of infection of the surgical site with the preventive use of negative pressure dressing in colorectal surgery. Case-control study with 40 patients in each group. Both groups, baseline without differences. Test t-student was used for the comparison of means in variables of normal distribution, while the Wilcoxon test was used for the comparison of means of non-normal distribution. The multivariate analysis was used in the study of risk factors. The wound infection is reduced with the use of negative pressure dressing from 25% to 7.5% p: 0.034 OR (0.006-0.964). The hospital stay is reduced from 12 to 8 days with the use of these dressings p: 0.22 The data have shown a significant reduction in the reduction of wound infection with the use of negative pressure dressings in a preventive manner in colorectal surgery
