[Effect of average-duration ether anesthesia on the behavior and clinical indices of dogs]

The investigations made use of ten clinically normal dogs which were subjected to an overall ether intubation anaesthesia with no surgical intervention, with the preliminary medication of a mixture of morphine and atropine applied subcutaneously. In the surgical phase (III)3 after Guedel there was full relaxation of muscles; full absence of the eye and the unconditional reflexes; downward rotation of the eye-balls; covering of the cornea up to one/third by the nictitating membrane; decrease in the lacrimal secretion and drying up of the cornea; lack of response at surgical intervention or at pricking with a needle in the interdigital space. The postnarcotic sleep continued 3-4 hours. The dogs came back to normal on the 3rd, 4th, and 5th day after anaesthesia.
