What Researchers Did
Researchers conducted a prospective randomized trial with 168 patients who had severe closed-head trauma to evaluate the effect of hyperbaric oxygen therapy (HBOT), administered at 1.5 ATA for one hour every 8 hours over two weeks, on patient outcomes.
What They Found
The study found that HBOT significantly reduced the mortality rate from 32% in 82 control patients to 17% in 84 treated patients. For those with initial Glasgow Coma Scale scores of 4-6, mortality dropped from 42% to 17%, and for patients with peak intracranial pressure greater than 20 mm Hg, mortality decreased from 48% to 21%. However, HBOT did not increase the number of survivors achieving a good recovery or moderate disability.
What This Means for Canadian Patients
For Canadian patients with severe closed-head trauma, these findings suggest that HBOT could potentially lower the risk of death. However, it is important to understand that while survival improved, the therapy did not increase the number of patients who achieved a good recovery or moderate disability.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A key limitation is that while HBOT reduced mortality, it did not increase the number of patients who achieved favorable long-term outcomes like good recovery or moderate disability.
