Abstract
A smooth and rapid recovery from anesthesia allowing safe release is desirable, especially for wild species. This study describes the clinical effects of the combination of dexmedetomidine and ketamine and the partial reversal with atipamezole in golden-headed lion tamarins. Dexmedetomidine 10μgkg-1 and ketamine 15mgkg-1 were administered to 45 golden-headed lion tamarins undergoing vasectomy. Following surgery, animals were assigned to three groups: control (SAL; 0.9% NaCl), atipamezole 20μgkg-1 (ATI20), and atipamezole 40μgkg-1 (ATI40). All animals presented great scores of sedation and muscle relaxation during the procedure. Recovery in the control group was smooth and uneventful. Salivation, muscle tremors, and head movements were observed in ATI 20 and ATI40. The administration of atipamezole did not change total recovery times (ATI20 69±23minutes; ATI40 72±45minutes; SAL 57±23minutes).
