Anestesia para osteossíntese de úmero em quati (Nasua nasua) - relato de caso

Abstract

Coatis are omnivorous mammals of the Procyonidae family, highly adaptable to urban environments and increasingly seen in these spaces due to the reduction of wild areas. Chemical restraint for field evaluation is already widely known, however, for complex anesthesia, in this species, there is a lack of reports and protocols. A specimen of Coati (Nasua nasua), an adult male, was delivered as a victim of a car accident to the Outpatient Clinic of Wild Animals of the Veterinary Hospital of the Federal University of Uberlândia. The physical examination identified a closed fracture in the middle third of the right humerus diaphysis, confirmed by radiographic examination. Surgical correction of the fracture was chosen and complementary exams were requested for pre-anesthetic evaluation, indicating patient ASA III. Was chosen as preanesthetic medication (PAM) an association of ketamine, diazepam and methadone at doses of 15, 0.3 and 0.15 mg/kg, respectively. Propofol was administered at a dose of 4 mg/kg for orotracheal intubation, followed by a brachial plexus block with bupivacaine at a dose of 2 mg/kg. Anesthetic monitoring was performed assessing temperature, heart and respiratory rate, mean arterial pressure, saturation of oxyhemoglobin and end-expiratory carbon dioxide concentration. The total surgery time was four hours and 30 minutes and there were no losses in anesthetic recovery or subsequent clinical presentation. Therefore, it was considered a successful protocol for a long-term anesthetic procedure.
