              Abstract 
 Aim:
              The aim was to evaluate and compare the clinico-physiological, 
              hemodynamic and hematobiochemical effects in response to different 
              total intravenous anaesthesia techniques using xylazine or 
              dexmedetomidine with propofol in canine patients. 
              Materials and Methods: Under a prospective randomized blinded 
              clinical study, 12 apparently healthy adult dogs (14.27±3.2 kg) 
              divided into two groups (n=6). Animals were administered with 
              xylazine (0.5 mg/kg body weight IV) in X group or, dexmedetomidine 
              (10 μg/kg 
              body weight IV) in D group and propofol (as IV bolus till the 
              induction and continuous IV infusion for maintenance). Clinical 
              reflexes, physiological, hemodynamic parameters, were recorded at 
              5-min intervals. Blood was collected at zero, 30 and 60 min after 
              initial injection for hematobiochemical evaluation. Statistical 
              analysis was performed using analysis of variance, Duncan’s 
              multiple range tests, paired - t-test and Kruskal–Wallis one-way 
              test. 
              Results: Animals showed quicker attenuation 
              of all clinical reflexes in group D. Induction doses of propofol 
              were 3.17±0.21 and 2.72±0.15 mg/kg and rate of infusion of 
              propofol for maintenance of anaesthesia were 0.33±0.02 mg/kg/min 
              and 0.35±0.02 mg/kg/min respectively in group X and D. Recovery 
              was quicker in group D. There were no significant statistical 
              differences in physiological, hemodynamic and hematobiochemical 
              parameters in both the groups. There were no adverse effects after 
              recovery. 
              Conclusion: Both anesthetic protocols provided satisfactory 
              immobilization, but dexmedetomidine-propofol combination may be 
              preferred owing to slightly better degree of basal anaesthesia, 
              lesser doses of propofol required for induction and maintenance of 
              anaesthesia along with a lesser degree of respiratory depression. 
              However, there was no clear preference for either of the protocol, 
              and both appear suitable for canines.  
              Keywords: alpha2 adrenoreceptor agonist, 
              canine surgery, dexmedetomidine, propofol, total intravenous 
              anaesthesia, xylazine.
