Abstract

The present clinical study assessed the clinico-physiological and haemato-biochemical effects of xylazine and dexmedetomidine as  preanaesthetic agents in dogs anaesthetised with tiletamine-zolazepam. A total of 12 dogs were presented for major surgical procedures.  They were randomly divided into two groups: Group I received xylazine (@ 1 mg/kg BW, IM) and Group II received dexmedetomidine  (@ 0.01 mg/kg BW, IM), followed by intravenous induction with tiletamine-zolazepam (@ 3 mg/kg BW till effect) and maintenance with  the same @ one-half of induction dose. Clinico-physiological and haemato-biochemical parameters were recorded before, during and  at 15 minutes intervals post-induction. Both anaesthetic protocols maintained cardiovascular and respiratory stability, time-dependent  variations observed within groups. No significant differences were noted between groups, indicating well-preserved cardiac function  and overall cardiovascular health. Haemato-biochemical parameters showed fluctuations but remained within normal physiological  limits confirming adequate hepatic and renal safety.
