RESUMO
Critical conditions that develop because of hypoxia of different genesis are accompanied by endogenous intoxication induced to a considerable degree by the appearance in the blood of an excess amount of medium-sized molecules (MSM). An appreciable increase of the content of MSM was demonstrated since the very first days after the brain stroke as a result of examining 100 patients who suffered brain stroke, including 83 patients during the first week of the disease and 17 patients of the reference group with a history of acute impairment of cerebral circulation which had occurred over a month before. A reverse correlation was established between the level of endogenous intoxication and the clinical status of the patients which could be observed every day during the acute disease phase. The critical level of MSM was determined in the patients' blood plasma. In the majority of cases, the attainment of the above level resulted in a lethal outcome irrespective of the pattern of acute impairment of cerebral circulation. The data obtained make it possible to recommend using the level of MSM as one of the simple and rapid quantitative methods for assessment of the patients' status gravity and monitoring of persons with acute impairment of cerebral circulation.
