What Researchers Did
Researchers conducted a non-randomised case-control study at an Indian neurorehabilitation unit, comparing outcomes in 22 hypoxic ischaemic encephalopathy patients who received HBOT (20-60 sessions at 2 ATA) versus controls across three injury time intervals.
What They Found
CRS-R scores significantly favored the HBOT group in patients treated 1-3 months and 4-8 months after injury. More patients in the HBOT group improved their disorder of consciousness classification. The benefit was not significant in patients treated 9-12 months after injury.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The non-randomised design with unequal group sizes and no blinding means results must be interpreted cautiously; patient selection differences between groups could explain the findings.
