Pentax-AWS videolaryngoscope for awake nasal intubation in patients with unstable necks.
British Journal of Anaesthesia 2010 January
In patients with unstable necks and at risk of pulmonary aspiration, awake fibreoptic intubation is often appropriate. However, stabilization of the neck can make fibreoptic intubation more difficult. I report the use of awake nasal intubation using the Pentax-Aiway Scope (AWS) in three patients with restricted neck movement, in whom awake fibreoptic intubation had failed. Case 1: a 59-yr-old man, at risk of aspiration, required an emergency cervical laminectomy. Awake fibreoptic intubation was attempted while a Halo vest was being applied, but it was impossible to see the glottis, mainly due to pharyngeal and laryngeal oedema. The Pentax-AWS was easily inserted orally, and nasotracheal intubation was achieved within 20 s. Case 2: an 85-yr-old woman with neck injury required emergency surgical stabilization. A retropharyngeal haematoma prevented a fibreoptic bronchoscope from being advanced beyond the epiglottis. Nasotracheal intubation using the Pentax-AWS (with the aid of a gum elastic bougie) was achieved within 1 min. Case 3: a 22-yr-old man, with partial spinal cord damage, was undergoing cervical laminoplasty. He was at risk of aspiration and had an oedematous larynx. Although it was possible to insert a fibreoptic bronchoscope into the trachea while the neck was stabilized with a Halo vest, it was impossible to advance a tube over the fibrescope. Awake nasotracheal intubation using the Pentax-AWS was achieved within 15 s. The Pentax-AWS may be useful for nasotracheal intubation in awake patients with restricted necks.
