What Researchers Did
Researchers reviewed medical records from 15 patients at Mayo Clinic to understand the causes, symptoms, and outcomes of cerebral air embolism.
What They Found
Out of 15 patients, 80% had focal deficits and 53% experienced coma. Computed tomography (CT) scans detected free air in only 4 of 13 patients who underwent this imaging. While 40% of patients received hyperbaric oxygen therapy, its use was not linked to better functional outcomes after one year in this group.
Canadian Relevance
This study covers arterial gas embolism, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
This study was limited by its small sample size of 15 patients and its retrospective design from a single institution.
