What Researchers Did
Researchers conducted a prospective study involving 60 patients with head injury coma, randomly assigning them to receive either daily hyperbaric oxygen therapy at 2.5 ATA or standard care.
What They Found
Overall, the study found no difference in mortality or mean duration of coma between the hyperbaric oxygen and standard therapy groups. However, in one specific subgroup of 18 patients (under 30 with a brain stem contusion without a supratentorial mass lesion), the rate of recovered consciousness at one month was significantly higher with hyperbaric oxygen therapy. Notably, 11 patients had their hyperbaric oxygen therapy interrupted due to complications.
What This Means for Canadian Patients
For Canadian patients with severe head injuries, this preliminary study suggests that hyperbaric oxygen therapy may not offer a general benefit for all cases. However, it indicates a potential for improved consciousness recovery in a specific subset: younger patients with brain stem contusions without other major brain lesions. Patients should consult their healthcare providers regarding appropriate treatment options.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study's preliminary nature and frequent interruptions of hyperbaric oxygen therapy in some patients limited its ability to definitively assess the treatment's overall effectiveness.
