Use of the Pentax-AWS® in 293 Patients with Difficult Airways

Abstract

The success rate of tracheal intubation using the Pentax-AWS was high in patients with difficult laryngoscopy with a Macintosh laryngoscope and in patients with predicted difficult intubation.

Tracheal intubation during chest compressions using Pentax-AWS®, GlideScope®, and Macintosh laryngoscope: a randomized crossover trial using a mannequin

“…Les donne´es suivantes ont e´te´mesure´es et enregistre´es : temps jusqu'a`intubation trache´ale re´ussie (crite`re d'e´valuation principal), taux de re´ussite global, temps jusqu'a`visualisation des cordes vocales, pourcentage d'ouverture glottique, compression dentaire et facilited 'intubation. Résultats Dans les cas de voies ae´riennes normales, les temps (moyenne [e´cart interquartile]) jusqu'a`intubation trache´ale e´taient plus courts avec le Pentax-AWS (12,1 [10,1-14,4] sec) et le GlideScope (14,3 [12,[4][5][6][7][8][9][10][11][12][13][14][15][16][17]6] sec) qu'avec le laryngoscope Macintosh (16,5 [13,,1] sec) (P \ 0,03 pour les deux). La diffe´rence de temps entre les deux vide´olaryngoscopes n'e´tait pas significative d'un point de vue statistique.…”

Are videolaryngoscopes useful for nasotracheal intubation?

“…In addition, its routine use may be impractical, partly because of the high cost of purchasing and maintaining the device. Rigid indirect-optical laryngoscopes (or 'videolaryngoscopes'), which are known to be useful for orotracheal intubation [7][8][9], may well be useful for nasotracheal intubation. Ono and colleagues, in this issue of the Journal of Anesthesia [2], studied 103 patients (without limited mouth opening), to assess the efficacy of the Airway Scope, and nasotracheal intubation was always successful within 30 s. A previous study [10] has also reported that nasotracheal intubation using another videolaryngoscope (Glidescope) was always successful in 34 patients.…”

Parker Flex-Tip Tube® provides higher intubation success with the Pentax-AWS Airwayscope® despite the AWS tip being inserted into the vallecula

“…When compared to the conventional Macintosh laryngoscope, the AWS has been proved to be an effective intubation device not only for patients with normal airways [2], but also for cases with difficult airways [3].…”
