This study presents the perianaesthetic management for eight dogs, aged between 3 and 9 years old that underwent a hemilaminectomy surgical procedure for medullar decompression. The patients were presented at the Faculty of Veterinary Medicine in Bucharest for acute onset of posterior unilateral paresis. Following the examination through magnetic resonance imaging, medullar compression was diagnosed at different thoraco-lumbar levels and surgery was recommended (hemilaminectomy). Four of the patients were premedicated with Fentanyl 3 μg/kg and Midazolam 0.2 mg/kg administered intravenously (IV) and the other four received Dexmedetomidine 2 μg/kg, Butorphanol 0.2 mg/kg and Ketamine 2 mg/kg intramuscularly (IM). For induction Propofol was administered IV at a dose of 3 mg/kg and patients were intubated. All patients had an epidural anaesthesia with Lidocaine (2 mg/kg). Maintenance consists in the administration of a constant rate infusion (CRI) of Fentanyl (3 μg/kg per hour) and Ketamine (1 mg/kg per hour) for the first four patients and a CRI of Lidocaine (3 mg/kg per hour) and Ketamine (1 mg/kg per hour) for the other four patients. Post-surgery multimodal analgesia protocols ensured pain control during recovery.
