What Researchers Did
Researchers retrospectively studied four comatose carbon monoxide-poisoned patients who did not receive hyperbaric oxygen therapy to assess their neuropsychologic and functional recovery.
What They Found
All four patients demonstrated normal performance on a neuropsychologic test battery and the Folstein Mini-Mental Status Examination at 6 months. Furthermore, all patients achieved normal functional outcomes.
Canadian Relevance
This study has no direct Canadian connection as it was conducted at a large, urban tertiary hospital outside of Canada.
Study Limitations
A significant limitation of this study is its very small sample size of only four patients, which limits generalizability.
