title: [Toxic activity of the blood plasma in the early postresuscitation period].
abstract: The time course of blood plasma toxicity was studied in dogs in the early postresuscitation period 10 minutes after clinical death because of acute hemorrhage. The duration of dying, the rate of the recovery of the main vitally important body functions were discovered to affect the rate of accumulation in the blood of substances with different molecular weights. There were 3 phases in blood plasma toxicity accumulation. The first phase is marked by the overflow of blood vessels with low-molecular substances, the second one by relative lessening of the content of low-molecular metabolites and an increase in the content of medium-molecular substances. The second phase is in agreement with the maximal rise of blood plasma toxicity. The third phase that develops by the 60th minute of the postresuscitation period is characterized by reduction of the peak activity of all substances under study and by overt toxicity with relative normalization of the main body functions.
