The aim of work was to test the using of reamberin on patients with cerebral deficiency due to severe forms of acute poisonings. The investigation was made on 60 patients (38 men and 22 women), whose average age was 34.7 +/- 2.6 (for men) and 28.4 +/- 3.2 (for women). The main group was divided into two parts, which had compared age, sex and gravity of condition. The first one was given reamberin with standart therapy (I - 32 patients), the second - only standart therapy (II - 28 patients). It was revealed that using of reamberin in complex therapy of acute cerebral deficiency lead to decrease of intensity of cerebral deficiency and to increase of speed of cerebral activity rehabilitation. These changes lead to improvement of clinic tendency of cerebral deficiency, what was illustrated by decrease of comatose period from 55.0+/- 2.2 to 33.0 +/- 2.6 hours, decrease of the time of being in reanimatology department from 69.1+/- 3.6 to 53.4+/- 4.3 hours.
