Brachial plexus block in a tamanduá-mirim (Tamandua tetradactyla) using a peripheral nerve stimulator: Case report

<p></p><p>ABSTRACT The aim of this study was to report the use of the neurolocalizer for blocking the bilateral brachial plexus in tamanduá-mirin. The subject weighing 5kg was attended by the Center for the Rehabilitation of Wild Animals and referred to the Veterinary Hospital of the Federal University of Mato Grosso do Sul for complementary tests. Through the examinations, the need to perform humerus and left radius/ulna osteosynthesis and cerclagem placement on right olecranon was established. For surgery performance, the patient was pre-medicated with ketamine S (5mg/kg-1) associated to midazolam (0.15mg/kg-1) via intramuscular and intravenous propofol (5mg/kg-1) was used for induction. The anesthetic maintenance was performed with isoflurane, provided by an oxygen mask. Cardiovascular and respiratory parameters were monitored throughout the procedure. Brachial plexus block was performed in both limbs using peripheral nerve stimulator. The local anesthetics used were lidocaine without vasoconstrictor (3mg/kg-1) plus 0.75% ropivacaine without vasoconstrictor (1mg/kg-1). Blocking was first performed on the right thoracic limb followed by the surgical procedure. The same blockage was performed on the contralateral limb. The patient had a smooth recovery, without vocalization and pain. The release to its natural habitat occurred after 120 days.</p><p>
