The mean results for heart rate and % SpO2 for the different anesthetic mixtures. The values for ketamine and xylazine (KX) include all three such groups, and the ketamine plus 500 μg/kg dexmedetomidine (KD500) value includes all six such groups. Values for DO (dexmedetomidine only), and for KO, KD4, KD20 and KD100 (ketamine plus zero, 4 μg/kg, 20 μg/kg and 100 μg/kg, respectively) include only the specific group.
