Clinical experiences with isoflurane in dogs and horses.

The inhalational anaesthetic agent isoflurane was administered to 22 dogs and 21 horses undergoing a variety of surgical procedures. Satisfactory anaesthesia was produced in all the animals. The cardiopulmonary changes were similar to those observed with halothane. Rapid changes in the depth of anaesthesia were achieved and recovery from anaesthesia was rapid in both dogs and horses, which was a reflection of the relative insolubility of isoflurane. Recovery from anaesthesia in the horses was particularly smooth and rapid with the animals spending a greater part of their recumbency in the sternal position, as opposed to lateral recumbency, before standing in a well coordinated manner.
