Clinical evaluation of enflurane in the dog

Enflurane (Ethrane; Abbott Laboratories Ltd), a new inhalation anaesthetic, was used on 30 clinical cases. A surgical plane of anaesthesia was quickly obtained and recovery was rapid. Respiratory depression occurred with a reduction in rate which was more marked in deeper planes of anaesthesia. Hypotension was not severe and was more marked in deeper plans of anaesthesia. Clinically the agent did not appear to be a good analgesic. No signs of spontaneous muscle activity were seen, possibly due to premedication with acepromazine.
