What Researchers Did
Researchers investigated the neuropsychological effects of severe carbon monoxide poisoning in 27 children and adolescents at two time points.
What They Found
Among 27 patients (mean age 11.8 years), the mean carboxyhemoglobin level was 31.5%. Only one patient experienced delayed neurological sequelae. Researchers found no correlation between carboxyhemoglobin levels and later neuropsychiatric test scores, but a correlation existed between loss of consciousness and anxiety, and hyperbaric oxygen therapy sessions and behavioral problems.
What This Means for Canadian Patients
This study highlights the potential neuropsychological impacts of carbon monoxide poisoning in children and adolescents. Canadian healthcare providers can use these findings to better identify and support pediatric patients at risk for anxiety or behavioral problems following CO exposure.
Canadian Relevance
This study was not conducted in Canada and has no direct Canadian connection.
Study Limitations
A limitation of this study is its relatively small sample size of 27 patients.
