Oxygen therapy reduces stroke damage ________________________________________ Aug 25 (HeartCenterOnline) – An oxygen treatment may reduce brain damage after a stroke, scientists report. Stroke (also called cerebrovascular accident or CVA) is a life-threatening event in which part of the brain is deprived of oxygen. It is most often caused by a blood clot (ischemic stroke). Hyperbaric (high-pressure) oxygen has been shown to protect brain tissue against damage from a stroke, but the effects of the oxygen therapy on the small blood vessels are little known, according to researchers in Heidelberg, Germany. They investigated whether hyperbaric oxygen after a stroke could decrease swelling (edema) in the brain and damage to the blood-brain barrier (a membrane that protects the brain). Studying rodents, the researchers blocked the middle cerebral artery for two hours. The control group breathed normal air, with the other animals given high-pressure oxygen. The researchers found that the hyperbaric treatment group had significantly less edema and significantly less damage to the blood-brain barrier. The article was published in the August issue of the journal Stroke. Copyright 2000-2005 HealthCentersOnline Inc. #stroke #hbot hbot4u 909.477.4545
