Treatment of Traumatic Brain Injury With Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy (HBOT) is defined as the use of oxygen at higher than atmospheric pressure for the treatment of underlying disease processes and the diseases they produce. Modern HBOT in which 100% O2 is breathed in a pressurized chamber dates back to the 1930s, when it was first used for treatment of decompression illness in divers. There are currently 13 FDA-approved uses for HBOT, including decompression illness, gas gangrene, air embolism, osteomyelitis, radiation necrosis, and the most recent addition—diabetic ulcers. HBOT can dramatically and permanently improve symptoms of chronic TBI months or even many years after the original head injury. This assertion is generally met with skepticism within the medical establishment because we have been taught for generations that any post-concussion symptoms persisting more than 6 months or so after a head injury are due to permanent brain damage that cannot be repaired.
The National Brain Injury Rescue and Rehabilitation Study – a multicenter observational study of hyperbaric oxygen for mild traumatic brain injury with post-concussive symptoms
The National Brain Injury Rescue and Rehabilitation Project was established as a preliminary study to test the safety and practicality of multi-center hyperbaric oxygen administration for the post-concussive symptoms of chronic mild traumatic brain injury as a precursor to a pivotal, independent, multi-center, controlled clinical trial. This report presents the results for 32 subjects who completed a preliminary trial of hyperbaric oxygen several years before the passage of the 21 st Century Cures Act. This study anticipated the Act and its reassessment of clinical research. Subjects received 40-82 one-hour treatments at 1.5 atmospheres absolute 100% oxygen. Outcome measures included repeated self-assessment measures and automated neurocognitive tests. The subjects demonstrated improvement in 21 of 25 neurocognitive test measures observed. The objective neurocognitive test components showed improvement in 13 of 17 measures. Earlier administration of hyperbaric oxygen post injury, younger age at the time of injury and hyperbaric oxygen administration, military status, and increased number of hyperbaric oxygen administrations were characteristics associated with improved outcomes. There were no adverse events. Hyperbaric oxygen was found to be safe, inexpensive and worthy of clinical application in the 21 st Century model of facile data collection provided by recent research regulatory shifts in medicine. The study was approved by the ethics review committee of the Western Institutional Review Board (WIRB; Protocol #20090761).
Erratum: Effect of hyperbaric oxygenation therapy on post-concussion syndrome.
The present review evaluated the effect of hyperbaric oxygenation (HBO) therapy on post-concussion syndrome (PCS). Searches for publications from the earliest date possible up until the first week of 2016 were conducted using the electronic databases Cochrane, EBSCOhost, Embase, Ovid MEDLINE, PubMed and Web of Science. Additional trials were identified through reference list scanning. Randomized controlled trials assessing the effectiveness of HBO therapy in PCS were selected and tested for eligibility for inclusion in the present review.
Effect of hyperbaric oxygen therapy on chronic neurocognitive deficits of post-traumatic brain injury patients: retrospective analysis.
The aim of the study is to evaluate the effect of hyperbaric oxygen therapy (HBOT) in participants suffering from chronic neurological deficits due to traumatic brain injury (TBI) of all severities in the largest cohort evaluated so far with objective cognitive function tests and metabolic brain imaging. A retrospective analysis was conducted of 154 patients suffering from chronic neurocognitive damage due to TBI, who had undergone computerised cognitive evaluations pre-HBOT and post-HBOT treatment. The average age was 42.7-14.6 years, and 58.4% were men. All patients had documented TBI 0.3-33 years (mean 4.6-5.8, median 2.75 years) prior to HBOT. HBOT was associated with significant improvement in all of the cognitive domains, with a mean change in global cognitive scores of 4.6-8.5 (p<0.00001).
