[Effect of fetanol on animal tolerance in ftorotan anesthesia]

Experiments on 20 dogs with simultaneous recording of bioelectrical activity of the brain cortex, medial thalamus, heart, arterial pressure, respiration and oxygen tension in brain tissues have shown that purposive correction of arterial hypotension with the aid of pharmacological substances, particularly fetanol increases the resistance of the brain cortex and respiratory center, thereby raising the animals' tolerance of increasing ftorotan anesthesia.
