CABRALES, Rodolfo Adrián et al. Efectividad de los apósitos de plata en la prevención de la infección del sitio operatorio en heridas contaminadas. Iatreia [online]. 2014, vol.27, n.3, pp.247-254. ISSN 0121-0793.

Introduction: Silver gauzes are designed to treat infected wounds, but there is controversial evidence about their effectiveness in preventing surgical site infections in contaminated wounds. Objective: To evaluate the effect of silver gauzes in patients undergoing surgery with contaminated wounds at a university-based tertiary referral center. Methods: This was a prospective, controlled trial comparing a silver gauze dressing with saline gauze dressings in patients undergoing abdominal surgeries with contaminated wounds. Patients were randomly assigned to receive either a silver gauze (SG) dressing or saline gauze dressings (SD). The primary end point was surgical site infection occurring within 30 days of surgery. Results: 65 patients were enrolled in the review. The incidence of surgical site infection was 14% (9/65). No differences were observed among groups (15.2% vs. 12.5%, p = 0.75). Multivariate analysis revealed no relationship between the type of dressing and surgical site infection. Conclusion: Silver gauzes are safe and effective in preventing surgical site infections in surgeries with contaminated wounds. Further trials are required to find out if they have advantages over standard dressings.
