What Researchers Did
Researchers reviewed cases of patients poisoned with carbon monoxide from indoor charcoal briquet burning who were referred for hyperbaric oxygen treatment.
What They Found
Out of 509 patients treated for acute unintentional carbon monoxide (CO) poisoning, 79 cases (15.5%) across 32 incidents were attributed to indoor charcoal briquet burning. These incidents primarily occurred between October and January, often during power outages, and disproportionately affected patients of minority races.
What This Means for Canadian Patients
Canadian patients should be aware of the severe risk of carbon monoxide poisoning when burning charcoal briquets indoors for heating or cooking. During power outages or in situations where electricity is unavailable, alternative safe heating and cooking methods should be prioritized to prevent such avoidable incidents.
Canadian Relevance
This study was conducted in the state of Washington, USA, and does not have a direct Canadian connection.
Study Limitations
This study is limited by its retrospective review of cases referred to a single tertiary care center, which may not represent the full scope of carbon monoxide poisoning incidents.
