Physical Treatment of Diabetic Foot Ulcers—Preliminary Study for Topical Application of Oxygen or Ozone Auxiliary Treatment of Diabetic Foot Ulcers.

Diabetes mellitus is one of the most common metabolic diseases in which one of the most serious complications is the diabetic foot ulcer (DFU). The aim of the study was to compare the efficacy of two physical therapeutic methods: topical oxygen therapy and topical ozone therapy in the treatment of DFU with the calculation of the financial costs for both applied physical methods. The study included 85 patients, 47 male (55.2%) and 38 female (44.7%) in age range between 40 and 90 years (mean age: 67.82 ± 12.42 years) with hard to heal diabetic foot ulcers. The mean diabetic foot ulcer duration was 3.6 ± 1.23 years. Patients were randomized into two study groups not significantly different in terms of age, body mass index (BMI) value, and baseline ulcer surface area value, who underwent topical oxygen therapy (group I) and topical ozone therapy (group II), respectively. Both the groups underwent a total of 30 daily treatments lasting 30 minutes, in 2 sessions of 15 treatments with a 14-day break between sessions. Progress in wound healing was evaluated by computerized planimetry and the pain intensity was assessed with use of a VAS scale. After the treatment, the ulcer area in group I decreased by an average of 33.25 ± 10.97% and by an average of 28.67 ± 14.47% in group II p = 0.030 . On the other hand, the intensity of pain ailments after the treatment was statistically significantly decreased in group I by an average of 57.13 ± 16.24% while in group II by an average of 40.21 ± 14.53% (p < 0.001). After application of topical oxygen therapy and topical ozone therapy in the treatment of diabetic foot ulcers a statistically significant reduction in the surface area of treated ulcers in objective planimetric assessment was observed, with local oxygen therapy showing only a slight advantage in this regard. Both compared methods also caused a statistically significant reduction in the pain intensity, while local oxygen therapy shows statistically significantly better analgesic effectiveness. Due to the calculated moderate cost, both applied methods appeared to be cost-effective. [ABSTRACT FROM AUTHOR]
