Comparative studies on enflurane anesthesia and halothane anesthesia in dogs.

Anesthesia was induced by one hour's inhalation with enflurane or halothane at a concentration of 1 or 2%. There was no particularly remarkable difference in clinical signs shown under or after anesthesia, or in hematological findings after anesthesia between enflurane and halothane. Therefore, the two anesthetics were almost equivalent in the evaluation of clinical application.Further investigations will be made in the following subjects : inhalation of an anesthesia at a high concentration; repeated anesthesia; effects upon the living body under anesthesia for a long time; clinical findings when some surgical stress is added to anesthesia; hematological findings; effects upon the cardiovascular and nervous systems.
