Abstract

In this study, we wanted to analyse the wound healing efficacy of collagen dressings as compared to povidone iodine dressings in acute diabetic foot ulcer patients, evaluate the difference in wound size between the two dressing groups along with the difference in the wound healing duration between the two groups. MATERIALS AND METHODS: This was a hospital based prospective comparative observational study conducted among 102 patients who presented with acute diabetic foot ulcers to the Department of General Surgery or from any other department in a Tertiary Care Referral Hospital in Mangalore, Karnataka, over a period of 2 years from October 2019 to September 2021, after obtaining clearance from Institutional Ethics Committee and written informed consent from the study participants. RESULTS: Males had a higher incidence of diabetic ulcers; this is statistically significant with a p value of 0.03. The quality of the ulcer bed was better in group A with 43 out of 51 patients having healthy granulation tissue and satisfactory ulcer bed (84.31 %) when compared to group B patients which had only 19 out of 51 patients who had satisfactory wound healing (37.25 %) on day 21; p = 0.004, which is statistically significant with collagen group showing better results. The collagen group had faster wound healing rates in comparison with the povidone iodine group, which is statistically significant. (p = 0.035) CONCLUSION: Collagen is a more efficient and readily available alternative to topical povidone iodine in patients with acute diabetic ulcers.
