What Researchers Did
Researchers reviewed patient records from a hyperbaric medicine center in Seattle to find out how often people intentionally poisoned with carbon monoxide had also taken other toxic substances.
What They Found
Out of 426 patients treated for intentional carbon monoxide poisoning, 188 (42%) had ingested one or more other toxic substances. Ethanol was the most frequently found co-ingestion, but many other types of drugs were also identified.
What This Means for Canadian Patients
For Canadian patients experiencing intentional carbon monoxide poisoning, this study suggests that other toxic substances might also be involved. Healthcare providers should look for signs of additional poisonings to ensure patients receive the most complete and effective treatment.
Canadian Relevance
This study covers carbon monoxide poisoning, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
A limitation is that toxicology screens were only performed on a small number of patients, and the study was a retrospective review from a single center.
