Reatment of Morganella Morganii-associated Non-healing Diabetic Foot Ulcer with Vaporous Hyperoxia Therapy: A Case Report

Introduction: Diabetic foot ulcers represent a significant complica- tion of diabetes mellitus, characterized by mechanical changes of bony architecture often leading to chronic wounds with increased risk of infection and impaired healing. Methods: Morganella morganii, a Gram-negative bacterium, is one of the pathogens found in infected diabetic foot ulcers. It is a human gastrointestinal commensal organism that may cause widespread deadly infections. This report discusses the case of a 76-year-old male with diabetes mellitus who presented with M. morganii diabetic foot ulcer to an in-patient rehabilitation facility. Results: Despite conventional wound care and antibiotic therapy, the ulcer failed to improve. The management approach for this patient con- sisted of a rehabilitation modality called Vaporox, a machine that utilizes vaporous hyperoxia therapy (VHT), as it combines ultrasonic mist and high concentration of oxygen to fasten revascularization and healing. Discussion: This case highlights the potential efficacy of VHT as an adjunctive therapy for the management of diabetic foot ulcers, particu- larly those complicated by pathogens, such as M. morganii.
