| Abstract: | Medetomidine 10 μg/kg, was combined with butorphanol 0.1 mg/kg and administered intramuscularly to 27 dogs requiring sedation for various diagnostic or therapeutic procedures. All the dogs became deeply sedated. Heart rate fell by a mean of 55 per cent. Eighteen dogs showed signs of pain as the combination was injected. Sedation was sufficient for the intended procedure to be carried out in 25 of the dogs. General anaesthesia was induced in four dogs — the mean dose of thiopentone required for induction of anaesthesia was 2 mg/kg. Administration of atipamezole at the end of the procedure produced rapid and sudden recoveries in all the dogs, with a mean time to standing of nine minutes. |
