What Researchers Did
Researchers presented a case report of a pregnant patient successfully treated with hyperbaric oxygen for acute carbon monoxide poisoning and reviewed existing literature on the topic.
What They Found
Carbon monoxide is the leading cause of death due to poisoning, and when it occurs during pregnancy, it can lead to foetal mortality and neurological malformations. A review of animal studies and human clinical experience indicated that the short duration of hyperbaric oxygen therapy for CO poisoning is tolerated by the foetus in all stages of pregnancy, reducing the risk of death or deformity for both mother and foetus. This was supported by a case report where a pregnant patient with acute CO poisoning was successfully treated with hyperbaric oxygen.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian participants or researchers.
Study Limitations
As a case report and literature review, this study's findings are limited by the inherent generalizability of a single case and the scope of the reviewed literature.
