Randomized Controlled Trial Comparative Study
Randomized controlled trial comparing the McGrath videolaryngoscope with the C-MAC videolaryngoscope in intubating adult patients with potential difficult airways.
Difficult and failed intubations, although rarely encountered, are major causes of morbidity and mortality in the current anaesthetic practice. To reduce the incidence of difficult and failed intubations, several devices including the recently developed videolaryngoscopes are available. This randomized controlled study aims to compare the use of the McGrath videolaryngoscope with the C-MAC videolaryngoscope in adult patients with potential difficult airways. ⋯ The C-MAC videolaryngoscope allowed a quicker intubation time, fewer intubation attempts, and greater ease of intubation compared with the McGrath videolaryngoscope when used in patients with the Mallampati grade of ≥3.

Securing the airway with supraglottic airway devices, such as a laryngeal tube, is a regular component of most difficult airway management algorithms. It is further recommended that in emergency medicine rescuers less skilled in endotracheal intubation should use supraglottic airways as a first line device. Exchanging the laryngeal tube with an endotracheal tube can be performed with video-assisted laryngoscopy as described below. ⋯ The C-MAC videolaryngoscope is a mobile system which facilitates endotracheal intubation in patients with a difficult airway and a laryngeal tube in place. It is not only possible but recommended to leave the laryngeal tube in situ as a back-up when videolaryngoscopy fails.

Randomized Controlled Trial Comparative StudyEfficacy of Coopdech videolaryngoscope: comparisons with a Macintosh laryngoscope and the Airway Scope in a manikin with difficult airways.
We studied the efficacy of the Coopdech videolaryngoscope Portable VLP-100, by comparing it with a Macintosh laryngoscope, and another videolaryngoscope, the Airway Scope (AWS), in a manikin with four simulated difficult airways. In a randomized, crossover design, each of 50 residents inserted the three devices, in turn, and graded the view of the glottis at laryngoscopy. Time to see the glottis, time to intubate the trachea, and the success rate of tracheal intubation (within 120 s) were recorded. ⋯ In a manikin with cervical spine rigidity or pharyngeal obstruction, the AWS and the VLP-100 provided significantly higher success rates of intubation than the Macintosh laryngoscope (P < 0.05). In a manikin with laryngospasm, no one could intubate the trachea using any device. Our results indicate that, in patients with difficult airways, the videolaryngoscopes (VLP-100 and AWS) would provide higher success rates of tracheal intubation than the Macintosh laryngoscope, but the VLP-100 may be inferior to the AWS.
