What Researchers Did
Researchers looked back at records of 113 patients treated with hyperbaric oxygen therapy for iatrogenic air embolism to understand factors affecting their recovery.
What They Found
Of the 113 patients, 71% presented with neurological disorders, 43% with respiratory issues, and 33% with hemodynamic problems. Overall, 69% recovered, 26% experienced lasting effects, and 5% died. Patients with venous emboli showed better improvement than those with arterial emboli. Hyperbaric oxygen therapy protocols varied, with neurological cases receiving initial compression to 6 atmospheres absolute (ATA) for 10-15 minutes followed by 100% oxygen at 2 ATA for one hour, while non-neurological cases received 100% oxygen at 2 ATA for one hour.
Canadian Relevance
This study covers iatrogenic gas embolism, which can include arterial gas embolism, a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
A limitation of this study is its retrospective design, which relies on existing patient records and may not capture all relevant details.
