Hawkins JR(1), Gonzalez KE(1), Heumann K(1).

Clinical Scenario: Concussions are a prevalent topic in medicine. Concussion
symptoms include headaches, dizziness, nausea, neuropsychiatric symptoms, and
cognitive impairments, the persistence of these referred to as postconcussion
syndrome. The use of hyperbaric oxygen therapy (HBOT) has been proposed and
evaluated as an additional treatment of these symptoms. Using HBOT is an
innovative approach that has been considered by many, but has received both
criticism and acceptance.CLINICAL QUESTION: Is hyperbaric oxygen therapy
treatment an effective means of reducing symptoms for individuals suffering from
postconcussion syndrome (persistence of symptoms for > 3 months)? Summary of
Search: The literature was searched for studies that were relevant to the
clinical question. Literature provided 5 level 1 studies that were relevant
enough to be considered. Clinical Bottom Line: Based on the research that is
available, we conclude that there is more evidence to refute the use of HBOT for
postconcussion syndrome than to support it. Strength of recommendation: Four
studies disprove the use of HBOT. One study supported the use of HBOT. These 5
studies are the same level of evidence (level 1), and provide significant
findings in their studies. The strength of this recommendation is a B according
to the Centre for Evidence-Based Medicine.
