Case Report: A 3‐year‐old female neutered greyhound presented for a dental procedure under general anesthesia. At the time of presentation, the dog was clinically well, with no health concerns from the client except for halitosis. The dog underwent general anesthesia with 13 teeth extracted and was stable until a severe, acute bradycardia was noticed at 2 h and 20 min postinduction. Venous blood analysis revealed a marked hyperkalemia. The dog was treated with calcium gluconate, an intravenous fluid bolus, glucose, and atropine. Serum potassium levels returned to within normal reference range at 60 min posttreatment. The dog developed ventricular tachycardia in recovery which responded to two lignocaine boluses. The dog was discharged from hospital in a stable condition. Conclusions: Unanticipated hyperkalemia during anesthesia was treated in an otherwise healthy greyhound undergoing a dental procedure.

Immobilisation and anaesthesia of wild felids may be complex and potentially dangerous events, making it difficult to implement more advanced anaesthetic techniques such as neuraxial anaesthesia. A Eurasian lynx was referred for femur fracture repair after it was seen with lameness of the left pelvic limb sustained in its natural environment. The animal was remotely darted using a combination of ketamine (5 mg/kg) and xylazine (5 mg/kg) intramuscularly. Once immobilised, the lynx was transported to the veterinary hospital in a restraining cage. After induction and endotracheal intubation, pelvic limb radiographs confirmed a closed, comminuted fracture of the left femur that required open reduction and internal stabilisation. A sacrococcygeal epidural was performed before surgery using lidocaine (2 mg/kg) and morphine (0.1 mg/kg) to complement the ketamine–xylazine–isoflurane anaesthesia, which allows a low‐end‐tidal isoflurane concentration. Clinical signs were continuously monitored and remained stable during the entire procedure, with the exception of a temperature that decreased to 35.8°C. No intraoperative analgesic rescues were necessary. Recovery was smooth and uneventful. The lynx showed no signs of motor weakness after surgery or other side effects related to the anaesthetic procedure. The successful management of this surgical case suggests that the described anaesthetic protocol could be recommended in orthopaedic procedures of the pelvic limbs in wild Felidae.
