Resumo
Background: The use of distinct drugs and techniques for establishing balanced anesthesia protocols has shown promisingresults in birds. The techniques of locoregional block can be incorporated to these protocols, thereby providing intra- andpost-operative analgesia and reducing the requirement for general anesthesia. Additionally, the use of neurostimulatorsincreases the chances of success and reduces the risk of toxicity; however, there are limited reports in the literature of itsapplicability in wild birds. Therefore, the aim of this study was to describe the brachial plexus block technique guidedusing a neurolocalizer in a striped owl (Asio clamator) submitted for right wing amputation.Case: A striped owl weighing 400 g with a history of exposed fracture of the right wing was supplied by the clinical sectorat the Veterinarian Hospital of the Federal University of Bahia. Following hydration and stabilization of vital signs, theanimal was referred to the surgical center for amputation of the limb. Dexmedetomidine (10 µg.kg−1 IM) was administeredas premedication, and after 20 min, anesthetic induction was performed using sevoflurane (FiO2 = 100%) via a mask followed by maintenance using the same drug. The animal was positioned in a left lateral decubitus position with access to thebrachial plexus determined by palpation and identification of the border of the following muscles: pectoral, cranial branchof the brachial biceps, and dorsal branch of the ventral serratus. The brachial plexus nerves are situated in the subcutaneous site craniodorsal to the axillary depression. For the block, a neurolocalizer was used, fixing the positive electrode toapproximately 5 cm from the needle insertion site (21G × 2) in the axillary depression, which remained connected to theneurostimulator by the second electrode. At first, the needle was attached to the peripheral nerve stimulator using a pulsefrequency of 1 Hz with an... (AU)
