Comparison of sedation scores and propofol induction doses in dogs after intramuscular premedication with butorphanol and either dexmedetomidine or medetomidine

Combined IM with butorphanol, medetomidine 0.01 mg kg−1 produced effective sedation more frequently than dexmedetomidine 0.005 mg kg−1 in dogs undergoing sedation prior to anaesthesia for elective procedures but this did not affect the propofol dose required for induction of anaesthesia significantly.
