Cervical spine movement during laryngoscopy using the Airway Scope compared with the Macintosh laryngoscope.
Anaesthesia. 2007 Oct; 62(10):1050-5.A

Abstract

The Airway Scope is a new rigid laryngoscope. This intubation device provides a non-line-of sight view of the glottis. A non-line-of sight view is expected to cause less movement of the cervical spine during laryngeal visualisation. We compared the degree of cervical spine movement during laryngoscopy with the Airway Scope and conventional direct laryngoscope. Twenty patients requiring general anaesthesia and tracheal intubation were studied. Movements of the cervical spine were measured using radiography in the same patient during laryngoscopy with the Airway Scope and a Macintosh laryngoscope. Cervical spine movement during laryngoscopy with the Airway Scope was 37%, 37% and 68% less than that with the Macintosh laryngoscope at the C0/C1, C1/C2 and C3/C4 motion segments, respectively (p < 0.05). The movement of the atlanto-occipital distance using the Airway Scope was 42% less than that during laryngoscopy using the Macintosh laryngoscope (p < 0.05). Laryngoscopy using the Airway Scope involves less movement of the cervical spine compared to conventional laryngoscopy using the Macintosh laryngoscope.
