What Researchers Did
Researchers investigated how hyperbaric oxygen therapy (HBOT) affected blood markers of inflammation and oxidative stress in ten patients with acute traumatic brain injury (TBI).
What They Found
Patients receiving early HBOT (30 sessions over six weeks, starting two weeks post-injury) showed higher serum glutathione (GSH) levels (1.40 μmol/L) at 10 weeks compared to late HBOT (1.16 μmol/L) and control (1.05 μmol/L). Early HBOT also decreased serum TBARS levels (11.21 μmol/L) at 10 weeks compared to late HBOT (17.23 μmol/L) and control (17.14 μmol/L). Late HBOT also increased GSH levels to 1.49 μmol/L by 18 weeks, with a statistically significant difference observed at this time point (p = 0.006).
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study was limited by its very small sample size of only ten patients and the lack of statistically significant differences in some key biomarkers at earlier time points.
