Background: In captivity, capuchin monkeys compete for space and rank. Fights can result in traumas, especially to the limbs, requiring interventions that are often outpatient. Local anesthesia as a tool in these procedures, as an aid to chemical restraint, is very relevant for small outpatient surgeries, or even for pain relief. Knowledge of peripheral nerve anatomy is essential to perform local anesthesia. Thus the objective of the present study was to determine, by anatomical studies of the brachial plexus region, the best access pathways for anesthetic blocking of the nerve. Materials, Methods & Results: Seven adult capuchin monkeys (Sapajus libidinosus) were used, weighing 2-3 kg, fixed and preserved in formaldehyde aqueous solution at 10%. In five of these animals the supraclavicular, infraclavicular and axillar regions were dissected to visualize the muscles, clavicle and bracchial plexus nerves. An analogical pachymeter was used to measure the depth of the plexus in relation to the cranial and caudal clavicle face and axillary fossa, comparing the length of two hypodermic needles (13x4.5 mm and 15x5 mm). Simulation of the anesthetic block was tested in two animals: before dissecting an acrylic varnish solution was injected using a syringe and 13x4.5 mm needle in the supraclavicular, infraclavicular regions and axillary fossa. To assess the positioning points of the [...](AU)
