Krebs cycle intermediates normalized gas exchange and decreased the mortality rate in rats with barbiturate coma. Treatment with other substrates including glucose and products of glycolysis was ineffective. Oxygen inhalation had no effect on oxygen consumption and indexes of external respiration. Our results suggest that deficiency of endogenous intermediates of the Krebs cycle, but not disturbances in oxygen mass transfer, serves as a limiting factor for oxygen consumption in rats with barbiturate coma.
