Summary

What Researchers Did

Researchers reported a case of a 31-year-old man with CO poisoning who experienced convulsive seizures and pulmonary oedema during his second HBOT session in a multiplace chamber.

What They Found

The seizure was managed with IV propofol and the HBOT session was terminated. Chest X-ray revealed bilateral pulmonary oedema. Echocardiography showed normal heart function, suggesting the oedema was from HBOT-related CNS toxicity triggering neurogenic pulmonary oedema. The patient recovered fully with no delayed neurological effects.

Canadian Relevance

No direct Canadian connection identified.

Study Limitations

This is a single case report from Japan; the exact incidence of seizures and pulmonary oedema in Canadian hyperbaric settings may differ based on protocols, patient selection, and monitoring practices.
