Silver colloid dressings score over conventional dressings in diabetic foot ulcer: a randomized clinical trial
Background: Topical silver treatments and silver dressings are increasingly used for the local treatment of contaminated or infected wounds; however, there is a lack of clarity regarding the evidence for their effectiveness. To compare the outcome of silver colloidal based dressing in comparison to conventional dressing in management of diabetic foot ulcers.Methods: This was a single institution prospective randomized controlled trial. Patients with Wagner grade 1and 2 diabetic foot ulcer were enrolled in this study. Patients were assessed on day one and then at two weeks interval for twelve weeks for ulcer size by planimetry.Results: Out of 25 patients, 13 were randomized to silver colloid group and 12 in conventional dressing group. Age and sex distribution was comparable among two groups. Total 29 ulcers were present in silver colloidal and conventional dressing group. Mean wound area in silver colloidal dressing group and conventional dressing group on admission was 36.8 and 20.46 cm2 respectively. After 12 weeks of dressing mean wound area in silver colloidal dressing group and conventional dressing group decreased by 31.52 (85.65%) and 14.04 (68.62%) and after 12-week complete healing was seen in 11 (84.62%) patients in silver colloidal dressing group and 5 (41.67) patients in conventional dressing group.Conclusions: The results suggest that silver colloidal based dressing had significantly better outcome in form of complete healing and decrease in ulcer size in comparison to conventional dressing in diabetic foot ulcers (p value <0.05).
