What Researchers Did
Researchers studied 175 patients with prolonged coma after severe traumatic brain injury to see how different arousal methods, including hyperbaric oxygen therapy, affected their recovery of consciousness.
What They Found
Out of 175 patients in prolonged coma, 110 (62.9%) recovered consciousness. Patients with shorter coma durations showed better recovery rates: 72.9% for those in coma for 1-3 months, compared to 47.6% for 4-6 months, and 26.7% for over 6 months. Recovery was also linked to factors like brain stem damage, cerebral hernia, Glasgow Coma Scale score, and age.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A limitation of this study is that it combined hyperbaric oxygen therapy with physical therapy and arousal drugs, making it difficult to determine the specific contribution or optimal protocol of HBOT alone.
