Comparison of the CMAC® Device to the Airtraq® and the Macintosh Laryngoscope in Patients With Anatomical Characteristics Predictive of Difficult Tracheal Intubation.
Summary
It is essential that anaesthetists successfully perform orotracheal intubation in scenarios in which intubation is potentially more difficult, such as where anatomical characteristics predictive of difficult intubation are present.
The CMAC® Laryngoscope is a new intubating device. It is designed to provide a view of the glottis without alignment of the oral, pharyngeal and tracheal axes.
The CMAC may be especially effective in situations where intubation of the trachea is potentially difficult.
The efficacy of this device in comparison to the traditional Macintosh laryngoscope and other novel laryngoscopes is not known.
We aim to compare its performance to that of the Macintosh laryngoscope, the gold standard device, in patients with one or more anatomical characteristics predictive of difficult intubation.
We further aim to compare it to the Airtraq® device a device which has been shown to be superior to the Macintosh laryngoscope in previous trials.
Our primary hypothesis is that, in the hands of experienced anaesthetists, time to intubation would be shorter using the CMAC than using the Macintosh laryngoscope in patients with two or more anatomical characteristics predictive of difficult intubation.
We further hypothesize that the Airtraq® will be superior the CMAC® with one or more anatomical characteristics predictive of difficult intubation.

Indirect Laryngoscopy for Nasal Intubation
Comparison of ease and convenience of nasotracheal intubation with the use of the two indirect laryngoscopes, Airtraq or Glidescope, versus the traditionally used Macintosh laryngoscope.

Comparing Performance of Airtraq Versus Macintosh Laryngoscope for Pediatric Intubation by Novices.
During laryngoscopy, the laryngoscope blade sometimes comes in contact with the teeth, fracturing or dislocating them. However, no studies have compared the effects of newly marketed video laryngoscop...
In patients with predictive features associated with easy direct laryngoscopy, videolaryngoscoy with the GlideScope has been shown to require less force when compared with Macintosh direct laryngoscop...
Direct laryngoscopy using a Macintosh laryngoscope is the most widely used approach; however, this skill is not easy for novices and trainees. We evaluated the performance of novices using a laryngosc...
Medical and Biotech [MESH] Definitions
Asthma
A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).
Safety-based Medical Device Withdrawals
Removal of a MEDICAL DEVICE from the market due to the identification of an intrinsic property of the device that results in a serious risk to public health.
Airway Remodeling
The structural changes in the number, mass, size and/or composition of the airway tissues.
Airway Management
Evaluation, planning, and use of a range of procedures and airway devices for the maintenance or restoration of a patient's ventilation.
Laryngeal Masks
A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.
