[Time course of toxic hypoxic encephalopathy during combined therapy including hyperbaric oxygenation]

The mechanisms of action of hyperbaric oxygenation (HBO) in toxic hypoxic encephalopathy (THE) were studied using clinical psychopathological examinations, functional and laboratory tests in 268 patients with THE treated by a therapeutic complex including HBO and 75 patients with THE treated routinely (controls). The earliest possible addition of HBO to a complex of treatment of THE patients led to involution of signs of brain edema shown by computer tomography (CT) and improvement of its functional activity, while in patients exposed to HBO later the psychoorganic symptoms and CT signs of cerebral ischemia did not disappear. Detoxifying, neuroimmunomodulating, and neuroimmunostimulating effects of HBO in THE were demonstrated. Early HBO treatment decreased the dysfunction of various compartments of the brain characteristic of THE. The technology of HBO developed by the authors prevented the development of socially dysadapting psychoneurological disorders and reduced the mortality of THE patients.
