Chronic wounds are an economic burden to the patient as they put him out of work and consume quality working days. Local insulin therapy is an innovative method in wound care which accelerates wound healing by increasing angiogenesis and granulation tissue formation. This study aims to evaluate its efficacy. OBJECTIVES: To study the efficacy of topical use of insulin in terms of (1) Rate of wound healing (2) Hospital stay. MATERIALS AND METHODS: This is a prospective study carried out in a tertiary health care center in 46 patients after taking informed and written consent. All patients who were satisfying inclusion and exclusion criteria were randomised into two groups A and B. Local insulin therapy was given to group A and normal saline dressing were done to group B. Size and depth were recorded at the start of the treatment and every week thereafter during the period of study. Strict glycemic control was maintained. Results were compared at complete wound healing or at the end of 8 weeks which was earlier. RESULTS: Improvement of the wound in the form of diameter and depth is seen. Significantly increased proliferation of granulation tissue is noticed in most of the patients belonging to group A, that is who received local insulin therapy. CONCLUSION: Local insulin therapy appears to be an efficacious method in the treatment of chronic diabetic foot ulcers and is safe and effective without any systemic side effects. It significantly reduces the hospital stay.
