What Researchers Did
Researchers described two pregnant women in their third trimester who experienced moderate carbon monoxide poisoning and were treated with hyperbaric oxygen therapy.
What They Found
Both women received hyperbaric oxygen therapy at 2.5 atmospheres for 90 minutes and delivered their babies at term. However, one of the two newborns developed a brain injury before birth, which was thought to be caused by the carbon monoxide poisoning.
What This Means for Canadian Patients
For Canadian patients experiencing carbon monoxide poisoning during pregnancy, this study highlights that hyperbaric oxygen therapy (HBOT) is a treatment option. It also suggests that even with maternal treatment, there can still be a risk of brain injury to the unborn baby, emphasizing the importance of prompt diagnosis and treatment.
Canadian Relevance
This study covers carbon monoxide poisoning, which is a Health Canada-recognized indication for hyperbaric oxygen therapy. No direct Canadian connection for the study or authors was identified.
Study Limitations
This study is limited by its small sample size of only two cases, which means the findings may not apply to all pregnant women with carbon monoxide poisoning.
