Extended anaesthesia and nasotracheal intubation of a red kangaroo (Macropus rufus)

Anaesthesia requires maintenance of a patent airway. Nasotracheal intubation of a red kangaroo (Macropus rufus) was performed when the inability to open the animal’s mouth prevented orotracheal intubation. Nasotracheal intubation was easy to perform, secured the airway and permitted delivery of supplemental oxygen, isoflurane and intermittent positive pressure ventilation.
