What Researchers Did
Researchers presented two case reports of patients with severe neurological impairment due to carbon monoxide intoxication who received delayed hyperbaric oxygen therapy.
What They Found
Two patients with severe neurological impairment, despite low admission carboxyhaemoglobin levels of 2% and 1.7%, responded well to hyperbaric oxygen therapy. In one of these cases, symptoms recurred several days later but also improved with further hyperbaric oxygen treatment.
What This Means for Canadian Patients
Canadian patients experiencing carbon monoxide poisoning with neurological symptoms might benefit from hyperbaric oxygen therapy, even if initial carboxyhaemoglobin levels are low or if treatment is delayed. This therapy could also be considered for recurrent symptoms following initial improvement.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in New Zealand.
Study Limitations
As a case study involving only two patients, the findings cannot be generalized to a larger population.
