Comparación de dos protocolos anestésicos en chigüiros (Hydrochaerus hydrochaeris itsmius) silvestres en el departamento de Córdoba, Colombia

Abstract

ABSTRACT: The aim of this study was to compare the effects of two anesthetic combinations: tiletamine/zolazepam 5 mg/kg IM and ketamine 10 mg/kg + xylazine 0.5 mg/kg IM in 16 free-living adult capybaras (Hydrochaerus hydrochaeris itsmius) captured in the department of Córdoba, Colombia. The subjects went through classic conditioning for their entrance to a cage trap where they were anesthetized with darts using a blowgun. Heart and respiratory rates, rectal temperature, muscle relaxation and side effects were evaluated. All these parameters were checked every 15 minutes during 60 minutes. The results showed that the two anesthetic combinations are safe and do not cause greatest collateral effects when administered intramuscularly in capybaras. Ketamine-xylazine combination produces greater bradycardic effects and inspiratory dyspnea compared to using tiletamine-zolazepam. For chemical restriction on animals with cardiac or respiratory compromise it could be counter-productive to use the ketamine-xylazine combination, if an 2-adrenergic antagonist is not available.. Both combinations are recommended for routine procedures
