BackgroundSilver has been used to reduce infection for centuries. This study retrospectively analyzed whether the introduction of silver-impregnated dressing (SD; Silverlon, Argentum Medical, LLC, Lakefront, GA) rather than RD (iodine- or alcohol-based swab and dry 4 x 4 gauze) would reduce the risk of superficial or deep infection after lumbar laminectomy with instrumented fusion.MethodsThe first 128 patients had RD applied postoperatively, whereas the second population of 106 patients received SD. These dressings were used for the first 2 weeks after surgery. Other clinical, surgical, and outcome data were comparable for both groups.ResultsThree of 128 patients who underwent multilevel laminectomies with instrumented fusions receiving RD developed deep postoperative wound infections (culture confirmed). All were successfully managed with 6 weeks of postoperative antibiotics, and none required secondary surgery. In addition, 11 patients who had RD developed superficial infection/irritation; 7 required oral antibiotics (7-10 days) alone, whereas 4 were referred to plastic surgeons for superficial wound revision. Alternatively, there were neither deep nor superficial wound infections/irritation among the 106 patients who received SD. Although the number of cases in each series was small, there appeared to be a positive trend toward a reduction in postoperative wound infection using SD.ConclusionsUse of SD for application on lumbar wounds after laminectomies with instrumented fusions appeared to limit/reduce the incidence of both postoperative deep and superficial wound infections.
