EFEITOS ANESTÉSICOS DA ADMINISTRAÇÃO INTRANASAL OU INTRAMUSCULAR DA ASSOCIAÇÃO DE MIDAZOLAM E CETAMINA RACÊMICA OU S+ EM PERIQUITO AUSTRALIANO (Melopsittacus undulatus) ANESTHETICS EFFECTS OF INTRANASAL OR INTRAMUSCULAR ASSOCIATION OF MIDAZOLAM AND RACEMIC OR S+ KETAMINE IN BUDGERIGARS (Melopsittacus undulatus)

Intranasal anesthesia in birds is considered a safe, simple and efficient technique. The aim of this study was compare the anesthetic effects of midazolam (5 mg.kg -1 ) with racemic (R) or S+ (S) ketamine (15 mg.kg -1 ), administered intranasally (IN) or intramuscularly (IM) in budgerigars (Melopsittacus undulatus). Eight budgerigars were used in a crossover design with four treatments: INR, INS, IMR and IMS. Onset time, dorsal recumbency time duration, total anesthesia time, total recovery time, sedation degree and recovery quality were evaluated. Significant differences were observed in onset
