Which scenario would be MOST appropriate for hyperbaric oxygen therapy in a wound clinic?

• A. A chronic diabetic foot ulcer that is infected
• B. A large abdominal wound from a recent hernia surgery
• C. A superficial burn covering the majority of the body
• D. A penetration wound that caused a pneumothorax

Answer: (A)

Hyperbaric oxygen therapy works by delivering 100% oxygen at higher-than-atmospheric pressure, which raises tissue oxygen tension. This boost in oxygen helps elevate neutrophil bactericidal activity, supports collagen synthesis and new blood vessel formation, and reduces tissue edema in areas of hypoxia. These effects make it a valuable adjunct for wounds where infection and poor oxygen delivery hinder healing, such as chronic diabetic foot ulcers.

In a chronic diabetic foot ulcer that is infected, HBOT aligns with these mechanisms and can enhance healing alongside standard care like infection control, debridement, and offloading. Diabetes often impairs microcirculation and immune response, so the extra oxygen during therapy can improve bacterial clearance and tissue repair, reducing the risk of complications.

Other scenarios don’t fit the typical HBOT indications. A large abdominal wound after recent hernia surgery is usually managed with local wound care and standard treatments unless there are specific complications that warrant HBOT. A superficial burn covering most of the body is not a standard HBOT indication and is typically treated with general burn care unless there are special circumstances. A penetrating wound with a pneumothorax is a contraindication to HBOT because the pressurized environment can worsen the pneumothorax.

So, the infection-laden chronic diabetic foot ulcer best matches the common, evidence-based use of hyperbaric oxygen therapy in a wound clinic.
