ISOFLURANE ANESTHESIA IN A RHINOCEROS

During surgical exploration of the reproductive tract of a 15-year-old female white rhinoceros, anesthesia was maintained by administration of isoflurane in oxygen. Anesthesia was induced with IM administration of etorphine, and, to facilitate endotracheal intubation, muscle rela xation was achieved by IV administration of additional etorphine, acep romazine maleate, guaifenesin, and thiamylal sodium. Minor complicatio ns encountered during the anesthetic monitoring period included hypove ntilation and ventilation/perfusion inequality, which contributed to h yperemia. Recovery was not evaluated because the rhinoceros was euthan atized at the end of the surgical procedure.
