What Researchers Did
Researchers retrospectively analyzed 331 pediatric CO poisoning patients at a Turkish children hospital over 10 years, examining predictors of severe disease including demographics, GCS scores, cardiac markers, and treatment type.
What They Found
93 patients received HBOT. 18 patients had severe disease course. The risk factors for severe disease were low Glasgow Coma Scale score, high leukocyte count, and high troponin T levels at presentation. Six patients died. GCS, leukocyte count, and troponin T predicted which children would have the most serious outcomes.
What This Means for Canadian Patients
CO poisoning in children is an OHIP-covered indication for HBOT in Ontario. This study provides Canadian pediatric emergency physicians with three simple, rapidly available tests -- GCS, white cell count, and troponin T -- to identify children with CO poisoning who are at highest risk and most need HBOT.
Canadian Relevance
Carbon monoxide poisoning is an OHIP-covered indication for HBOT in Ontario.
Study Limitations
This was a retrospective single-center study from Turkey; patient demographics, CO exposure patterns, and healthcare access differ from Canada.
