[Course of ether anesthesia and the post-anesthesia period against a background of prior vibration]

The experiment on albino rats showed that three-hour vibration (46.6 Hz, 1mm amplitude) decreases the functional activity of the central nervous system as well as that of the respiratory and circulatory apparatus. Ether anesthesia against this background aggravates the animals condition and they die during the post-anesthesia period (60% of cases). Survival of the animals under conditions of extreme actions (vibration, anesthesia) is estimated by the cerebral cortex resistance level.
