[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.
