What Researchers Did
Researchers treated 230 patients with acute carbon monoxide poisoning, with 203 receiving hyperbaric oxygen (HBO) based on specific neurological criteria and 27 receiving normobaric oxygen.
What They Found
Out of 230 patients, 4 died, and 7 experienced minor neurological problems within two weeks of discharge, which resolved within one month. Additionally, 2 patients were re-hospitalized for neuropsychiatric sequelae, recovering within 3 to 6 months, and neither admission status nor carboxyhemoglobin levels predicted outcomes.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study's observational design and lack of a randomised comparison between hyperbaric and normobaric oxygen for all patients limit the generalizability of its findings.
