The C-MAC videolaryngoscope: first experiences with a new device for videolaryngoscopy-guided intubation.
We studied the efficacy of the C-MAC (Karl Storz, Tuttlingen, Germany), a new portable videolaryngoscope, in 60 patients during routine induction of anesthesia. It was possible to insert the blade (Size 3) of the C-MAC and to get a view of the glottis on the first attempt in all patients. Tracheal intubation also was successful in all 60 patients; 52 patients were intubated on the first attempt, 6 on the second, and 2 on the third. ⋯ The median time taken for tracheal intubation was 16 s (range, 6-58 s). In addition, we describe our experience with 3 patients in whom we had unexpected difficulty with direct laryngoscopy with a conventional Macintosh laryngoscope (Cormack-Lehane Class 3, 4, and 4, respectively). These patients' airways were successfully managed on the first attempt when using the C-MAC Size 4 blade (improvement to Cormack-Lehane Class 1, 2a, and 2b, respectively) in a modified manner by uploading the epiglottis, which is known as "straight blade technique."

Case Reports
Pentax-AWS videolaryngoscope for awake nasal intubation in patients with unstable necks.
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. ⋯ 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.

Randomized Controlled Trial Comparative Study
Comparison of a single-use GlideScope Cobalt videolaryngoscope with a conventional GlideScope for orotracheal intubation.
This study was conceived to compare the single-use GlideScope Cobalt videolaryngoscope with the conventional GlideScope videolaryngoscope for orotracheal intubation, as judged by time to intubation (TTI) and ease of intubation. ⋯ The GlideScope Cobalt has similar performance characteristics compared with the conventional GlideScope videolaryngoscope when used for orotracheal intubation. The two devices can likely be used interchangeably. (ClinicalTrials.gov number, NCT00459797.).
