What Researchers Did
Doctors describe one patient with severe (grade 3-4) frostbite in both feet who was treated with hyperbaric oxygen therapy along with other standard treatments.
What They Found
This case report describes a patient who developed frostbite three days after an 11-day walk in cold, snowy, wet conditions in Tasmania, Australia, and was treated with hyperbaric oxygen along with vasodilator and rheological (blood flow-improving) drugs. The treatment seemed to reduce the area of poor blood flow (ischemia) in both feet. The authors state this possibly reduced how much of the toe joints needed to be amputated. No specific pressure, session count, or numeric outcome measures are reported in the abstract.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This is a single case report from one patient with no comparison group, so it cannot establish that hyperbaric oxygen caused the outcome or predict results in other patients.
