Abstract
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/zolazepam + medetomidine (TZM). For KM, the induction time was 9.67 ± 4.36 min, reaching and maintaining a level of anesthesia by 56.11 ± 11.55 min. Atipemazole (antagonist of the medetomidine) was administered 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 administered considering it as a safe option for immobilization of free-ranging ocelots. / Thirteen free-ranging ocelots (Leopardus pardalis) were captured for health studies in the Rio Hondo valley of Madidi National Park, Bolivia and two different anesthetic protocols for immobilizations were evaluated; the combinations of ketamine + medetomidine (KM) and tiletamine/zolazepam + medetomidine (TZM). For KM, the induction period was 9.67 ± 2.36 min, with an anesthesia plane duration of 56.11 ± 11.55 min. Administration of the antagonist for medetomidine was at 59.2 ± 20.26 min, animals recovered at 10.44 ± 9.83 min and escaped at 16.89 ± 11.41 min after recovery, with a total time of 97.11 ± 31.21 min from injection of the initial dose to exit from the trap. With the TZM combination, induction was 4.25 ± 0.96 min with an anesthetic duration of 51.5 ± 8.74 min. The antagonist for medetomidine, atipamezole, was injected at 57.5 ± 10.89 min, with animals recovering at 21.25 ± 16.15 min after atipemazole, and escaping at 28.75 ± 12.20 min after recovery, for a total duration of 111.75 ± 13.30 min from initial injection to trap exit. Anesthesia with both protocols was safe and effective for the required maneuvers. With the TZM combination, the induction time and drug volume were significantly reduced, making it a safe option for anesthesia of free-living ocelots.
