laryngoscope
Introduction
A tube with lighting for examining or operating on the larynx through the mouth.
Airtraq, a single-use optical laryngoscope, may be superior to direct laryngoscopy using a Macintosh blade for intubation in both routine airways & difficult airways.[2][3]
Airtraq also causes less cervical spine movement than a Macintosh blade.[4][5]
The Pentax Airway Scope (AWS) & the GlideScope are high-resolution video laryngoscopes. The AWS has an integrated channel designed to help guide the endotracheal tube through the glottis.[6]
AWS is available only in adult sizes.
Storz V-MAC results in better glottic views & higher intubation success rates than the GlideScope Ranger & McGrath video laryngoscopes, when used without stylet. The more exaggerated angle of the GlideScope Ranger & McGrath blades might aid visualization in certain difficult airways but necessitates use of a stylet. Use of a stylet has been associated with palatal perforation.[7]
