RESUMEN
BACKGROUND: The objective of the present study was to study the anatomy of the respiratory system of Sapajus libidinosus. METHODS: Ten corpses of adult animals were used. To analyze the bronchial tree, transparent acetic silicone was injected and then dissected. RESULTS: The trachea presented a mean of 32 rings. These spaces were delimited for tracheostomy and tracheotomy between the 1st and 3rd ring or between the 9th and 11th ring, and for thoracocentesis at the 7th or 8th intercostal space. For tracheostomy and tracheotomy, the best access point was in the ventral region of the neck and transverse incision of the rings. For thoracocentesis, cranioventral insertion of the catheter is recommended in the 8th intercostal space. CONCLUSIONS: The trachea and lung anatomy applied to clinical and surgical procedures the robust capuchin monkey is similar to both wild and domestic carnivores.

BACKGROUND: Epidural anesthesia is indicated to decrease other anesthetic requirements, prolong analgesia, and reduce side effects. In primates, its use has been scarcely described. The aim was to evaluate the cardiorespiratory effects of epidural anesthesia with lidocaine and dexmedetomidine (DEX) or morphine (MOR). METHODS: Ten female capuchin monkeys (Sapajus sp.) received epidural anesthesia with lidocaine and DEX or MOR under general anesthesia. RESULTS: There was a significant decrease in heart rate with DEX and in blood pressure in all groups, with no changes in SpO2 . There was a significant reduction in rectal temperature over time. A stable cardiac rhythm was observed; however, there was a prolonged QT interval with DEX. CONCLUSIONS: Epidural anesthesia with access to the lumbosacral space was safe and easy to perform. DEX decreased heart rate. All groups promoted a decrease in rectal temperature with respiratory and cardiac rhythm stability; however, hypotension should be considered.
