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.
What This Means for Canadian Patients
Canadian patients experiencing a stroke after cardiac surgery might benefit from hyperbaric oxygen therapy, even if treatment is delayed. This therapy could potentially improve neurological outcomes and facilitate a return to their previous level of care.
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.
