Uso da combinação dos anestésicos tiletamina e zolazepam na imobilização de Ctenomys lami (Rodentia-Ctenomyidae) no sul do Brasil Use of the anesthetic combination of tiletamine and zolazepam for immobilization of Ctenomys lami (Rodentia-Ctenomyidae) in southern Brazil

Studies about chemical contention are extremely important for wildlife animal’s manipulation, to guaranty safety of it and the people who are manipulating them. Zoletil ® was used for contention of tuco-tucos (Ctenomys lami) captured in Rio Grande do Sul state (Brazil) between May and June of 2008. The dosage utilized was 8mg/kg by intramuscular injection. The induction time was 2,5±1,05min. The reflex recuperation (when the animals returned to be on sternal decubitus) took 37,3±12,32min and the ambulation return occurred in 52,83±14,32min. No adverse reaction to Zoletil unless a little temperature regulation loss. Two individuals deceased during anesthesia process. This anesthetic showed to be effective as immobilization agent for tuco-tucos in wildlife.
