AbstractBackgroundMany primates are kept in breeding for scientific or conservation purposes, but much of the clinical care is represented by trauma. To provide more effective interventions in some of these cases, the present study aimed to evaluate the technique of local anesthesia through the epidural space in capuchin monkeys (Sapajus libidinosus).MethodsTen animals were used, which have been deposited in the epidural space 1% lidocaine at a dose of 0.3 ml/kg over the lumbosacral joint. Heart and respiratory rates, oxygen saturation in arterial hemoglobin, blood pressure, rectal temperature, nociception, and cutaneous sensitivity were assessed before and after application.ResultsThe technique promoted loss of sensation of the skin and muscle relaxation of the pelvic limbs, tail, and perineal region for a period of 35 minutes without any of the physiological parameters measured varies beyond normal values.ConclusionsThe technique proved easy to perform, safe, and effective.
