The current study assesses the effects of methylene blue along with the use of platelet-rich plasma-fibrin glue on wound healing in patients with nonhealing diabetic foot ulcers (non-healing DFU). This randomized controlled trial is performed on 20 patients with non-healing DFU. Patients were treated with PRP-FG dressing plus 200 ml of oral methylene blue dissolved in milk(intervention group) or PRP-FG dressing plus placebo (200 ml of milk) (control group) for 4 weeks.
The aim of this study is to evaluate the chance of non-healing diabetic foot ulcers repair by improving the condition of lack of oxygen or hypoxia in the wound area caused by diabetes using methylene blue along with the use of platelet-rich plasma-fibrin glue as an effective treatment for wound healing.
