Dr Paul Harch M.D. speaks to Congress about value of Hyperbaric Oxygen Therapy


On May 2, 2002 Dr. Paul G. Harch, Clinical Assistant Professor of Medicine of the Louisiana State University School of Medicine, New Orleans was invited and presented evidence for a restorative effect of


low pressure HBOT on chronic brain injury before the Subcommittee on Labor, Health, Human Services, and Education of the House of Representatives Appropriations Committee. The testimony consisted of functional brain imaging (SPECT) documentation of improvements in brain blood flow in 15 patients with a variety of chronic brain injuries.

Chronic Traumatic Brain Injury: TBI is a condition that affects nearly 2 million U.S. citizens annually and leaves approximately 6 million chronically impaired. The figures are significantly underestimated because of the under diagnosis and under reporting of mild TBI. Dr. Harch showed multiple cases of improvement in brain blood flow and clinical condition in chronic TBI. Most of the cases were many years old.

Cerebral Palsy: Dr. Harch showed a dramatic improvement in brain blood flow in an 8 year old CP boy. The child experienced behavioral and neuro-cognitive gains.

Alzheimer's Disease: The testimony featured the first known case of HBOT improvement of an Alzheimer's patient. The Oklahoma patient had plateaued on the last of all available experimental and approved drug therapies. Post HBOT brain scans demonstrate impressive increases in brain blood flow in the areas typically affected by Alzheimer's Disease with concomitant mild cognitive benefits.

Autism: The testimony features one of the few cases of autism treated with HBOT in the United States. The brain blood flow improves along with the patient's behavior and social interaction.

Alcoholism and Substance Abuse: Two impressive cases are featured, an elderly alcoholic man with a severe stroke and a 19 year old with chronic substance abuse. Both cases highlight the diffuse restorative potential of HBOT on the substance abused brain and patient.

Shaken Baby: The testimony shows the devastating injury of a shaken baby with partial improvement from low pressure HBOT. This is one of three cases that Dr. Harch has treated.

Carbon Monoxide and Toxic Brain Injury: These cases demonstrate the effectiveness of low pressure HBOT on yet another neuropathology.

The diversity of cases in the testimony and the uniform results from Dr. Harch's low pressure protocol of HBOT strongly suggest a generic effect of HBOT on the chronically injured brain. The impressive brain scans demonstrate the power of this treatment modality.

Animal Data
The above human data, while irrefutable from the vantage of functional imaging, was significantly bolstered by confirmatory animal data in early 2001. In 1996 Dr. Harch sought a model of chronic brain injury to validate his clinical studies. A controlled pilot experiment with 12 rats was implemented using the Feeney Open Head Bonk model of brain contusion. This experiment demonstrated significant improvement in cognitive function and matching improvements in brain blood flow with are identical to the human clinical experience. Believing this was a statistical fluke of small numbers of animals Dr. Harch's co-researcher Dr. Rob Sutherland of the University of New Mexico urged replication with a larger number of animals. In January, 2001 the results were returned on 60 rats with greater statistical significance. This represents the first ever non-invasive improvement of chronic brain injury in animals in the history of science. More importantly, it duplicated the human cases in the congressional testimony above.
