A two-year-old, female walrus was presented with dento-alveolar abscesses. Tusk extraction was performed under general anesthesia using isoflurane. The walrus was atropinized (0.01mg/kg), and sedated with ketamine hydrochloride (3mg/kg) and diazepam (0.1mg/kg) injected intramuscularly. Anesthesia was induced using thiopental sodium (5 mg/kg) administered through an intravenous catheter placed within the extradural vein. Anesthesia was maintained with oxygen-isoflurane mixture. When the respiration rate decreased to less than 1 breath per min after administration of thiopental sodium, intermittent positive-presssure ventilation was performed at 10 breaths per min. The heart rate remained at approximately 100/min. The respiratory rate returned to normal 40 min after anesthesia.
