Cardiorespiratory effects of epidural anesthesia using lidocaine with morphine or dexmedetomidine in capuchin monkeys (Sapajus sp.) undergoing bilateral tubal ligation surgery, anesthetized with isoflurane.

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.
