Dexmedetomidin-midazolambutorfanol kombináció hatásai vörös rókák (Vulpes vulpes) anesztéziája során
Abstract
Summary
Background: There are different approaches to the sedation or anaesthesia of
the red fox (Vulpes vulpes). Published drugs and drug combinations include ketamine plus different alpha2-agonists, tiletamine-zolazepam, medetomidinemidazolam, medetomidine-butorphanol-midazolam and medetomidine alone.
Objectives: To evaluate the anaesthetic and physiological effects of a dexmedetomidine-midazolam-butorphanol combination in red foxes. Prospective study.
Materials and Methods: Ten healthy, young adult (8–12 months old) male
red foxes were included, average weight of the animals was 5.0 kg. Foxes were
treated with 0.01 mg/kg dexmedetomidine, 0.57 mg/kg butorphanol and 0.45
mg/kg midazolam by hand given intramuscular injection. All animals were castrated using a prescrotal approach and 2 mg/kg lidocaine was applied subcutaneously and intratesticularly immediately after lateral recumbency was achieved
to support analgesia. No oxygen supplementation was used for the procedures.
Animals were given 0.1 mg/kg atipamezole intramuscularly at the end of procedure. 0.2 mg/kg meloxicam was applied at the end of surgery in all animals to
give further analgesia.
Results and Discussion: All of the animals reached light plain of surgical
anaesthesia and intubation was possible. Average time to lateral recumbency
was 12 minutes. Average heart rate was 88/min, respiratory rate 24/min, while
blood oxygen saturation was 90% without oxygen supplementation. No major
changes of these parameters were revealed with time. No electrocardiogram
(ECG) abnormalities were observed. Animals were able to stand within five minutes from the application of atipamezole. No fatalities or emergencies were
experienced in any animals and all of them recovered from surgery without
complications.
