What Researchers Did
Researchers retrospectively analyzed wound healing outcomes in 73 patients with 85 non-healing lower extremity wounds undergoing a six-week course of hyperbaric oxygen therapy.
What They Found
Healing responses varied, with 31 wounds showing robust healing (over 50% reduction), 33 showing minimal healing (15% reduction), and 21 showing non-healing (60% increase in area). Cigarette smoking was significantly associated with poor response (p<0.0001), while diabetes was not, and robust responders were younger with higher creatinine, urea nitrogen, and peripheral oxygenation.
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy for non-healing wounds may experience variable outcomes, with some not benefiting from the treatment. Clinicians should consider factors such as age, smoking status, and specific lab values to better identify which patients are most likely to respond positively to HBOT.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
As a retrospective study, it relies on existing data and may be limited by uncontrolled variables or selection bias.
