Immobilization of captive tigers (Panthera tigris) with a combination of tiletamine, zolazepam, and detomidine.

The aims of this study were to evaluate the effects of the administration of a combination of tiletamine-zolazepam and detomidine (TZD) in 9 tigers (Panthera tigris). Nine captive tigers were immobilized with tiletamine-zolazepam and detomidine administered intramuscularly. At the end of the procedure immobilization was partially reversed with atipamezole. Lateral recumbency was achieved in 15.6 ± 5.9 min. The median induction score [scored 1 (excellent) to 4 (poor)] was 1. The immobilization score [scored 1 (poor) to 6 (too deep)] was 5 (4-5) at all study times. After atipamezole administration, all tigers experienced severe ataxia and incoordination. Median recovery score [scored 1 (excellent) to 4 (poor)] was 2.5 (range 2-3). No neurologic and/or important adverse reactions were noticed within 5 days after recovery. The combination tiletamine-zolazepam with detomidine proved to be effective in immobilizing captive healthy tigers but it maybe associated with hypertension and ataxia during recovery.
