Disorders in the Functional State of the Central Nervous System, Intestinal Peristalsis and Microbiocenosis in Experimental Barbiturate Poisoning

Following a single administration of sodium thiopental in high doses (85 mg/kg intraperitoneally), the animals demonstrated the absence or weakening of reflexes at the levels of the spinal cord, medulla oblongata, bridge and midbrain and cerebral cortex over the period of one day. Other signs included a pronounced hypothermia, a decrease in the respiratory rate and a violation of its rhythm, a distinct tendency to bradycardia. On days 1-3 after the administration of sodium thiopental, a restoration of the respiratory rate, heart rate, body temperature, and the functional state of the central nervous system at various levels was observed, with the exception of the cerebral cortex. In the long term, following the administration of sodium thiopental for up to 21 days, a depression of the functional state of the central nervous system at the level of the cerebral cortex, violation of coordinated propulsive peristalsis of the small intestine and intestinal microbiocenosis were detected. Hence, in experimentally simulated barbiturate poisoning, not only is the suppression of the functions of the central nervous system observed, but also significant and prolonged restructuring of the functional state of the gastrointestinal tract.
