What Researchers Did
Researchers conducted a randomised controlled double-blind trial to compare hyperbaric oxygen with normobaric oxygen for neurological sequelae in patients with carbon monoxide poisoning.
What They Found
The study found that more patients in the hyperbaric oxygen group required additional treatments (28% vs 15%, P = 0.01 for all patients). Furthermore, hyperbaric oxygen patients showed a worse outcome in the learning test at treatment completion (P = 0.01 for all patients).
Canadian Relevance
This study was conducted in Australia and has no direct Canadian connection.
Study Limitations
A limitation of this study is its single-center design, which may affect the generalizability of the findings.
