What Researchers Did
Researchers retrospectively analyzed patients with iatrogenic cerebral gas embolism (CGE) referred to The Alfred Hospital hyperbaric unit to assess if hyperbaric oxygen treatment (HBOT) improved outcomes.
What They Found
Of 45 patients with iatrogenic cerebral gas embolism, 36 received hyperbaric oxygen treatment (HBOT), and 4 (8.9%) died. Good neurological outcomes were observed in 27 patients, and the only independent factor associated with a good outcome was a shorter time to the first HBOT (OR 0.94, P = 0.05).
What This Means for Canadian Patients
Canadian patients experiencing iatrogenic cerebral gas embolism may benefit from hyperbaric oxygen treatment, especially if administered promptly. Rapid diagnosis and transfer to a hyperbaric facility are critical to maximize the chances of a good neurological recovery.
Canadian Relevance
This study has no direct Canadian connection as it was conducted at The Alfred Hospital in Australia.
Study Limitations
As a retrospective study with a relatively small sample size, this research may be subject to selection bias and limitations in data completeness.
