What Researchers Did
Researchers cataloged the side effects of 2.4 atmospheres absolute hyperbaric oxygen versus sham treatment for post-concussion symptoms in military service members with combat-related mild traumatic brain injury.
What They Found
Researchers found that ear block occurred in 5.51% of all exposures (1.09% sham, 5.91% treatment), sinus squeeze in 0.14% (0% sham, 0.27% treatment), and confinement anxiety in 0.27% (0.27% sham, 0.27% treatment). Other mild side effects like headache (0.61%) and nausea (0.2%) were also reported, with no major adverse events such as pulmonary barotrauma or seizures observed.
What This Means for Canadian Patients
Canadian patients considering hyperbaric oxygen therapy for mild traumatic brain injury may be reassured by the low incidence of severe side effects reported in this study. This information can help patients and their healthcare providers weigh the potential benefits against the minimal risks when making treatment decisions.
Canadian Relevance
This study has no direct Canadian connection as it was conducted with military service members in the United States.
Study Limitations
A limitation is that the study population consisted solely of military service members with combat-related traumatic brain injury, which may limit the generalizability of these findings to other patient groups.
