NALLAR, Rodolfo. Comparison of two protocols of immobilization with ketamine + medetomidine VS tiletamine/zolazepam + medetomidine on free - ranging ocelot (Leopardus pardalis) in Madidi National Park, Bolivia. Ecología en Bolivia [online]. 2010, vol.45, n.1, pp.55-63. ISSN 1605-2528.

Thirteen free-ranging ocelots (Leopardus pardalis) were captured for health studies in the Rio Hondo valley of the Madidi National Park, Bolivia. Two different anesthetic protocols were evaluated; the combination of ketamine + medetomidine (KM) and tiletamine / zolazepan + medetomidine (TZM). For KM, the induction time was 9.67 ± 4.36 min, reaching and maintaining a level of anesthesia by56.11 ± 11.55 min. Atipemazole (antagonist of the medetomidine) was administrated at 59.2 ± 20.26 min, recovering 10.44 ± 9.83 min, and escaping at 16.89 ± 11.41 min after recovery. The total time for KM was 97.11 ± 31.21 min from the initial dose injection until the exit of the trap. On the other hand, for the TZM, induction and anesthesia were 4.25 ± 0.96 min and 51.5 ± 8.74 min respectively. After injected atipemazole, 57.5 ± 10.89 min, ocelots recovered in 21.25 ± 16.15 min and they escaped from the trap 28.75 ± 12.20 min after recovery, totaling 105.25 ± 13.30 min from the initial injection until the exit of the trap. The immobilizations in both protocols were safe and effective for the maneuvers required. With TZM the induction time was reduced significantly as well as the volume of the drug administrated considering it as a safe option for immobilization of free-ranging ocelots.
