This prospective, randomised clinical trial compared pain, comfort, exudate management, wound healing and safety with Hydrofiber dressing with ionic silver (Hydrofiber Ag dressing) and with povidone-iodine gauze for the treatment of open surgical and traumatic wounds. Patients were treated with Hydrofiber Ag dressing or povidone-iodine gauze for up to 2 weeks. Pain severity was measured with a 10-cm visual analogue scale (VAS). Other parameters were assessed clinically with various scales. Pain VAS scores decreased during dressing removal in both groups, and decreased while the dressing was in place in the Hydrofiber Ag dressing group (n = 35) but not in the povidone-iodine gauze group (n = 32). Pain VAS scores were similar between treatment groups. At final evaluation, Hydrofiber Ag dressing was significantly better than povidone-iodine gauze for overall ability to manage pain (P < 0.001), overall comfort (P < or = 0.001), wound trauma on dressing removal (P = 0.001), exudate handling (P < 0.001) and ease of use (P < or = 0.001). Rates of complete healing at study completion were 23% for Hydrofiber Ag dressing and 9% for povidone-iodine gauze (P = ns). No adverse events were reported with Hydrofiber Ag dressing; one subject discontinued povidone-iodine gauze due to adverse skin reaction. Hydrofiber Ag dressing supported wound healing and reduced overall pain compared with povidone-iodine gauze in the treatment of open surgical wounds requiring an antimicrobial dressing.

Objective: To evaluate the safety and performance of Medicel Tulle Dressing (MTD) in subjects with chronic or acute wounds left to heal by secondary intention. Method: This 28-day, multi-centre, single-arm clinical study was conducted at seven sites in France. Thirty patients with a chronic (n=20) or acute wound (n=10) were treated with MTD and gauze as a secondary dressing. Study treatment lasted 28 days or until healing. Results: Mean baseline wound area was 14.8cm2. There were 103 clinic dressing changes and 220 home dressing changes. Seven adverse events were reported in five subjects, including one treatment-related adverse event of dry scab. No adherence was reported for 66% of clinic dressing changes and 53% of home dressing changes. No trauma was reported for 96% of clinic dressing changes. Mean reduction in wound size was 7.0cm2. Conclusion: In this study, MTD demonstrated good safety results. Additional study is warranted to confirm the clinical utility of MTD in the management of chronic or acute wounds left to heal by secondary intention. Declaration of interest: This study was supported by ConvaTec, a division of ER Squibb & Sons, New Jersey, US.
