“…On the other hand, intubation time was shorter with the Macintosh laryngoscope in patients undergoing cervical spine surgery with equivalent laryngeal views . The rate of oral or pharyngeal injury may be higher with the Macintosh laryngoscope than with the Pentax AWS , or it may be similar .…”

Pentax Airway Scope^® vs Macintosh laryngoscope for tracheal intubation in adult patients: a systematic review and meta‐analysis

SummaryThe Pentax Airway Scope â is a single-use optical videolaryngoscope designed to assist with difficult tracheal intubation. We systematically reviewed the efficacy of the Pentax Airway Scope with that of a conventional laryngoscope for tracheal intubation in adults with 'normal' and 'difficult' airways. We included 17 randomised controlled trials with a total of 1801 participants. We used the DerSimonian and Laird random-effects model to calculate pooled relative risk or weighted mean differences. The relative risk (95%

“…Video and optical laryngoscopes Intubation using the Pentax AWSÒ (Pentax Medical Company, Montvale, NJ, USA) has been compared with intubation using a conventional MAC 4 blade, 85 and success was similar. More data are available on the GlidescopeÒ (Verathon Medical Inc., Bothell, WA, USA), including intubation times and success comparable with oral fibreoptic intubation under anesthesia, 86 better views and reduced difficulty with intubation compared with the MAC 4 blade, 87 and success in the awake intubation scenario -although the success rate on first attempt was only 54%, 12% required three attempts, and 4% were failures.…”

“…However, recent studies comparing the GlideScope video laryngoscope (Verathon, Bothell, WA, USA) and the Pentax AWS (Ambu, Inc., Glen Burnie, MD, USA) to Macintosh DL for intubating morbidly obese subjects failed to support the superiority of VL in this patient population [1, 2]. Additionally, financial constraints, particularly in developing nations, make substitution of the far more costly VL devices for the traditional DL blades impractical.…”

Background. Teaching direct laryngoscopy is limited by the inability of the instructor to simultaneously view the airway with the laryngoscopist. Our primary aim is to report our initial use of the GlideScope Direct, a video-enabled, Macintosh laryngoscope intended primarily as a training tool in direct laryngoscopy. Methods. The GlideScope Direct was made available to anyone who planned on performing direct laryngoscopy as the primary technique for intubation. Novices were those who had performed <30 intubations. Results. The GlideScope Direct was used 123 times as primarily a direct laryngoscope while the instructor viewed the intubation on the monitor. It was highly successful as a direct laryngoscope (93% success). Salvage by indirect laryngoscopy occurred in 7/9 remaining patients without changing equipment. Novices performed 28 intubations (overall success rate of 79%). In 6 patients, the instructor took over and successfully intubated the patient. Instructors used the video images to guide the operator in 16 (57%) of those patients. Seven different instructors supervised the 28 novices, all of who subjectively felt advantaged by having the laryngoscopic view available. Conclusions. The GlideScope Direct functions similarly to a Macintosh laryngoscope and provides the instructor subjective reassurance, while providing the ability to guide the trainee laryngoscopist.

A Randomized Comparison Between the Pentax AWS Video Laryngoscope and the Macintosh Laryngoscope in Morbidly Obese Patients

Abstract: The time required for tracheal intubation using the Pentax AWS was longer than for the Macintosh laryngoscope and #4 blade. The AWS should not routinely be substituted for a conventional Macintosh #4 blade in morbidly obese patients.
