What Researchers Did
Researchers described a rare case where a 70-year-old patient developed a cerebral air embolism after a lung biopsy procedure, which was successfully treated with hyperbaric oxygen therapy.
What They Found
This case report highlighted that cerebral air embolism following a transbronchial needle aspiration (TBNA) is extremely rare, with an estimated incidence of 0.02-0.07%. A 70-year-old patient experienced an epileptic seizure and left-sided paralysis immediately after TBNA, and subsequent brain imaging confirmed air embolisms. The patient's neurological symptoms completely resolved after several hyperbaric oxygen therapy sessions.
Canadian Relevance
Although this study was not conducted in Canada, it covers arterial gas embolism, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
As a single case report, the findings cannot be generalized to a larger population, and further research would be needed to confirm these results across more patients.
