:• Maintain anaesthesia either with incremental doses of ketamine or inhalational anaesthesia either via a nasal airway in the other nostril connected to the breathing circuit or using a specially designed facemask with a port for insertion of the fibreoptic bronchoscope. | :• Maintain anaesthesia either with incremental doses of ketamine or inhalational anaesthesia either via a nasal airway in the other nostril connected to the breathing circuit or using a specially designed facemask with a port for insertion of the fibreoptic bronchoscope. | ||
:• Use a topical vasoconstrictor to prevent bleeding from the nose during FOI, as otherwise this may make intubation impossible. Pseudoephedrine, ephedrine, phenylephrine, oxymetazoline, or nasal packs soaked in 1:10,000 adrenaline may be used, depending on local availability. | :• Use a topical vasoconstrictor to prevent bleeding from the nose during FOI, as otherwise this may make intubation impossible.

:• Apply topical lidocaine to the nose and oropharynx. Larger fibreoptic laryngoscopes often have a channel through which local anaesthesia can be injected. Alternatively an epidural catheter can be passed through the suction port (if present) and local anaesthetic injected through this. Be careful not to exceed the maximum dose of lidocaine (3mg.kg-1 i.e. 0.3ml.kg-1 of a 1% solution). | :• Apply topical lidocaine to the nose and oropharynx.
