What Researchers Did
This retrospective review examined the outcomes of 12 patients who received hyperbaric oxygen therapy for post-cardiac surgical strokes at Christchurch Hospital.
What They Found
Despite treatment delays of up to 48 hours, 10 of the 12 patients (83%) achieved full neurological recovery or had mild residual symptoms, with 9 returning to their previous level of care. One patient remained hemiplegic, and one experienced an early neurological death.
Canadian Relevance
This retrospective study was conducted in Christchurch, New Zealand, and does not have a direct Canadian connection.
Study Limitations
A key limitation is the paucity of prospective data in this area, as this was a retrospective case series.
