What Researchers Did
Researchers conducted a prospective, open-label feasibility study to assess recruitment, tolerance, and safety of hyperbaric oxygen therapy for chronic sequelae after brain injury.
What They Found
Sixty-three participants with chronic stroke, anoxia, or trauma-related brain injury were enrolled, with 53 completing the intervention. The study met feasibility criteria for recruitment, though 44% of participants required additional time to complete the 60 hyperbaric oxygen sessions. HBO2-related adverse events were rare and not serious, and many participants reported symptom improvements, including 51% for memory and 51% for attention/concentration.
What This Means for Canadian Patients
This feasibility study suggests that hyperbaric oxygen therapy for chronic brain injury sequelae may be tolerable and safe, potentially paving the way for larger randomized controlled trials. If proven effective in future studies, this therapy could offer a new treatment option for Canadian patients living with long-term effects of brain injury.
Canadian Relevance
This study was conducted in a tertiary academic hospital outside of Canada, with no direct Canadian involvement or specific Canadian patient population.
Study Limitations
As an open-label feasibility study, this trial was not designed to definitively assess the efficacy of hyperbaric oxygen therapy for chronic brain injury sequelae.
