Evaluation of Propofol Anaesthesia inMedetomidine-Pentazocine and Midazolam-Pentazocine Premedicated Buffalo Calves
Abstract:
Twelve buffalo calves of either sex presented to the college clinic with various surgical conditions were utilized to study the effect of continuous intravenous infusion of propofol after premedication with medetomidine – pentazocine and midazolam – pentazocine. The animals were divided into two groups of six animals each. Group I animals were premedicated with Medetomidine @ 2.5 µg/kg b.wt. – pentazocine @ 0.5 mg/kg b.wt IV and Group II animals received midazolam @ 0.25 mg/kg b.wt. – pentazocine @ 0.5 mg/kg b.wt. IV.. Propofol was given @ 4 mg/kg b.wt. IV after premedication and maintained by continuous intravenous infusion of propofol @ 0.4 mg/kg b.wt. in 5 % dextrose normal saline in both groups. Induction quality was excellent, smooth and attained sternal recumbency rapidly without struggling in both groups. Anaesthetic character, Physiological & haematobiochemical parameters were studied at 0, 5,10,15,30 and 60 minutes following anaesthetic injections. No significant changes were recorded in both the groups. ECG studies did not reveal any abnormalities except slight variations in the amplitude of P wave, T wave and QRS complex in both groups. The study suggests that medetomidine – pentazocine premedication with continuous intravenous infusion of propofol provided better surgical anaesthesia and was compatable and safe in buffalo calves.
