Hyperbaric oxygen therapy and the diabetic foot.

Area of Science:

• Wound Healing
• Hyperbaric Medicine
• Diabetic Complications

Background:

• Diabetic foot ulcers often fail to heal due to infection and ischemia, compounded by impaired immune responses in diabetic patients.
• Diabetes mellitus compromises cellular and humoral immunity, affecting leukocyte function and inflammatory responses crucial for wound repair.
• Oxygen is vital for wound healing, and hyperbaric oxygen therapy (HBOT) can elevate tissue oxygen levels.

Purpose of the Study:

• To discuss the potential benefits of hyperbaric oxygen therapy (HBOT) as an adjunct treatment for diabetic foot ulcers.
• To review existing evidence, including anecdotal reports, retrospective, and prospective studies on HBOT for diabetic wounds.

Main Methods:

• Review of literature on the role of oxygen in wound healing and the effects of HBOT on diabetic patients with foot ulcers.
• Discussion of HBOT's mechanisms, including increased tissue oxygenation, enhanced leukocyte activity, and antimicrobial effects against anaerobes.

Main Results:

• Existing studies suggest HBOT may be beneficial for managing diabetic foot wounds.
• Anecdotal reports and some prospective studies indicate positive outcomes with HBOT.
• Methodological limitations in current studies necessitate further investigation.

Conclusions:

• Hyperbaric oxygen therapy (HBOT) shows promise as an adjunctive therapy for diabetic foot ulcers.
• There is a critical need for high-quality, international, randomized controlled trials to establish HBOT as a standard treatment.
• A multidisciplinary approach is essential for managing diabetic foot lesions effectively.
