An Extra Breath of Fresh Air: Hyperbaric Oxygenation as a Stroke Therapeutic

Abstract: Stroke serves as a life-threatening disease and continues to face many challenges inthe development of safe and effective therapeutic options. The use of hyperbaric oxygen therapy(HBOT) demonstrates pre-clinical effectiveness for the treatment of acute ischemic stroke and reportsreductions in oxidative stress, inflammation, and neural apoptosis. These pathophysiological benefits contribute to improved functional recovery. Current pre-clinical and clinical studies are testing the applications of HBOT for stroke neuroprotection, including its use as a preconditioning regimen.Mild oxidative stress may be able to prime the brain to tolerate full extensive oxidative stress that occurs during a stroke, and HBOT preconditioning has displayed efficacy in establishing such ischemic tolerance. In this review, evidence on the use of HBOT following an ischemic stroke is examined, and the potential for HBOT preconditioning as a neuroprotective strategy. Additionally, HBOT as a stem cell preconditioning is also discussed as a promising strategy, thus maximizing the use of HBOTfor ischemic stroke.
