Background: The maned wolf (Chrysocyon brachyurus) is the largest south american canid and deemed a near threatenedspecies according to the International Union for Conservation of Nature (IUCN). Typically found in Brazilian Cerrado, it isoften a victim of animal trappings and vehicular accidents, where it may get deeply injured or end up fractured, demandingorthopedic procedures. Even though maned wolves are similar to the domestic dog, little is described regarding generalanesthesia and its complications for major procedures in ill patients in the scientific database. This case report describesa successful blood transfusion and anesthetic management of a critically ill C. brachyurus.Case: An adult female maned wolf was rescued after getting steel-jaw trapped. After chemical restraint with intramuscular(IM) ketamine (12 mg/kg), midazolam (0.3 mg/kg) and methadone (0.3 mg/kg), physical examination showed exposedbones to the distal end of the right hind limb, pronounced dehydration and moderate anemia and thrombocytopenia according to blood count. Radiographic images enlightened multiple right tarsus fractures. As the wound was highly infected,which made the osteosynthesis procedure impossible, it was decided to amputate the limb on the following day. Subcutaneous (SC) lactated Ringer’s solution (250 mL), IM meloxicam (0.2 mg/kg) and IM enrofloxacin (10 mg/kg) were alsoadministered at first. On the following day, after aforementioned chemical immobilization, anesthesia was induced withdose-effect intravenous (IV) propofol (2 mg/kg) until orotracheal intubation was possible, and general anesthesia wasmaintained with isoflurane diluted in oxygen. Lumbosacral epidural anesthesia was obtained with 0.5% bupivacaine (0.25mL/kg) and morphine (0.1 mg/kg) to provide analgesia and to reduce inhalant agent...(AU)
