Anesthetic protocol for Sapajus libidinosus (nail monkey) submitted to vasectomy and ligation of elective tubes

Abstract

Safe and effective capture, immobilization or anesthesia of wild animals, such nail monkey (Sapajus lididinosus), is generally required for research and management purposes, as well as surgical and diagnostic procedures, and of the neotropical species, it is the one that presents greater geographical distribution. The genus has been used in several researches, given its phylogenetic proximity to the human species, serving as a biological model in experiments applied to this species There are a variety of anesthetic protocols used so that the capture and handling of nail monkey is performed simply and safely. The objective of this study is to report the use of the combination of dexmedetomidine with ketamine, morphine and midazolam for the chemical restraint of eight adult nail monkeys submitted to two surgical procedures, to vasectomy and ligation of elective tubes, with the goal of establishing a safe and effective chemical containment and containment protocol for the species in captivity. During the surgical procedures the physiological parameters of heart rate and respiratory rate and rectal temperature and oxyhemoglobin saturation by pulse oximetry of the eight nail monkeys were monitored. At the end of the surgeries, the animals received atipamezole intramuscularly. The protocol used was safe and effective for the chemical containment of nail monkeys in captivity submitted to different surgical procedures allowing reversal of the pharmacological effects at the end of the surgery.
