What Researchers Did
Researchers reviewed the scientific evidence, including recent randomized controlled trials, on the use of hyperbaric oxygen therapy for diabetic foot ulcers.
What They Found
They found that typical hyperbaric oxygen (HBO) treatment for diabetic foot ulcers involves 20 to 40 sessions, each lasting 90 to 120 minutes at 2.0 to 2.5 absolute atmospheres. While earlier evidence was weak, two recent well-designed randomized controlled studies have provided stronger support for HBO's effectiveness in a selected group of patients, showing consistent positive outcomes for ulcer healing.
What This Means for Canadian Patients
For Canadian patients with chronic diabetic foot ulcers, hyperbaric oxygen therapy may be a beneficial treatment option, particularly for those who meet specific selection criteria. Patients should discuss with their healthcare providers whether HBO is appropriate for their individual condition, considering its potential to improve ulcer healing.
Canadian Relevance
This study does not have a direct Canadian connection as it is a review of international evidence.
Study Limitations
Earlier studies on hyperbaric oxygen therapy had methodological limitations, and health economic analyses are constrained by deficient primary clinical data.
