KADAM topical warm oxygen therapy device for diabetic foot ulcer-a novel approach

Purpose: Diabetic foot ulcer (DFU) is a significant healthcare burden demanding prompt attention. In the past decade, newer technologies such as topical oxygen therapy have grown increasingly popular. The purpose of the study was to determine effect of KADAM-a topical warm oxygen therapy (TWOT) medical device in healing of DFU. Methods: The KADAM medical device developed by Yostra Labs Pvt Ltd, delivered pure oxygen between 93 ± 3% concentration at an optimal temperature range of 39-42º Celsius to DFU wound site. Results: A total of 40 diabetic foot ulcer individuals, aged over 18 years were included in the study. Individuals with the Grade 1 DFU were 34 (85%), grade 2 were 5 (12.5%) and grade 3 were 1 (2.5%). The changes in initial area and final area for the various diabetic foot ulcer grades were as follows: 0.32 [0.12, 0.96] (< 0.001) for grade 1 ulcer, 0.76 [0.54, 1.17] (P = 0.013) for grade 2 ulcer and 1.26 for grade 3 ulcer. The percentage reduction in wound size achieved for the grade 1 & 2 DFU were 100%, and grade 3 was 75%. Conclusion: Topical warm oxygen therapy serves as an adjunctive modality to facilitate diabetic foot ulcer healing in the clinical practice.
