ABSTRACT Locoregional anesthesia reduces the requirement for inhaled agents and reduces the autonomic responses to noxious surgical stimuli. The aim of this study was to describe an anesthetic block of the brachial plexus guided by a neurostimulator in a donkey submitted to right limb amputation. Preanesthetic medication was performed with detomidine 0.01mg.kg-1 induction with diazepam 0.05mg.kg-1 and ketamine 2mg.kg-1 all intravenously, and maintenance of anesthesia with isoflurane. The brachial plexus was blocked by subscapular access, using a neurostimulator. For this purpose, 1mg.kg -1 of bupivacaine 0.5%, without vasoconstrictor, and 1mg.kg- 1 of lidocaine 2%, without vasoconstrictor were used. The values of HR and ƒ during the surgical procedure ranged from 62 to 78bpm, and 24 to 32bpm, respectively. Four blood samples were collected for cortisol dosing. This, prior to the application of the pre-anesthetic medication was 6.4ug/dL and 30 minutes was 2.8ug/dL. Anesthesia recovery was rapid and uncomplicated. Neurostimulator-guided brachial plexus blockade proved to be effective in donkeys, providing satisfactory analgesia and anesthesia.
