What Researchers Did
Researchers conducted a systematic review to evaluate the benefits and harms of hyperbaric oxygen therapy for acute, subacute, or chronic stroke.
What They Found
The review identified only four randomized controlled trials and one controlled clinical trial. The best available evidence from these trials indicated no benefit of hyperbaric oxygen therapy for stroke patients. Additionally, 17 observational studies were found, all of which were deemed to be of poor quality.
What This Means for Canadian Patients
Based on this review, Canadian patients with stroke should not expect significant benefits from hyperbaric oxygen therapy. Current evidence does not support its routine use for acute, subacute, or chronic stroke management.
Canadian Relevance
This systematic review did not include any specific Canadian data or patient populations.
Study Limitations
The generalizability of the findings is limited due to significant variability in patient characteristics, stroke types, and hyperbaric oxygen therapy dosages across the included studies, and the poor quality of observational studies.
