[The characteristics of the neurophysiological diagnosis and the main directions in the differentiated therapy of brain edema and swelling in patients who are in a critical state].

A total of 186 patients with encephalopathies caused by critical states and reanimation were examined. A complex of neurophysiologic studies was proposed involving impedancemetry of the brain, rheoencephalography, echoencephalography, electroencephalography, ophthalmoscopy. The studies made showed that adoption of the proposed complex permits differentiating the processes of edema, swelling, edema-swelling of the brain as well as determining the condition of cerebral bloodflow and assessing the extent of impairement of cerebral homeostasis. Early diagnosis of edema/swelling of the brain enabled the main trends in the differential therapy of the above processes to be outlined and adequacy of its treatments administration to be effectively controlled on an as-needed basis. Differential approach to diagnosis and treatment of edema and swelling of the brain permitted the parameters studied to return to normal in 75.2 percent of the patients.
