Tracheal Intubation of a Difficult Airway Using Airway Scope, Airtraq, and Macintosh Laryngoscope

Abstract

Both the AWS and ATQ may be suitable devices for difficult intubation by inexperienced personnel in this manikin simulated scenario. Further studies in a clinical setting are necessary to confirm these findings.

Influence of clinical experience of the Macintosh laryngoscope on performance with the Pentax-AWS Airway Scope®, a rigid video-laryngoscope, by paramedics in Japan

“…The AWS requires fewer operator skills to achieve intubation, which is useful in emergency settings [3,4] and for difficult airways [5-7] and appears to be particularly suitable for novices [8][9][10][11].…”

“…We ensured that our study had a sound rationale and ethical basis, justified by (a) the widespread and safe use of the AWS as an aid to intubation in routine clinical practice, (b) the lack of reporting of any severe adverse events with the AWS, and (c) published evidence showing the clinical utility of the AWS in the OR and emergency scenarios-particularly for novice personnel [8][9][10][11]. Furthermore, we took the necessary steps to gain the approval of the relevant government agencies and the local Medical Control and Ethics Committees as previously described.…”

Airtraq laryngoscope: a solution for difficult laryngeal exposure in phonomicrosurgery

“…Hypoesthesia and immobility of tongue, loss of taste, injury to the upper teeth and laceration of the lateral tonsillar pillar, which usually occurred in phonomicrosurgery using a suspension laryngoscope [18], were not observed. This could be explained by the fact that an anatomically shaped blade of Airtraq V R essentially enables easier and better access to the glottis and laryngeal lesions and allows an atraumatic placement in virtually all anatomical configurations with remarkably reduced forces exerted on the tongue, upper teeth, and oropharyngeal soft tissue [12,19]. Another outstanding advantage is that Airtraq V R , in combination with a highresolution camera and video monitor, can provide very fine and magnified images of the larynx and, thus, enables a precise monitor-guided operation.…”

Comparison of Pentax-AWS Airwayscope video laryngoscope, Airtraq optic laryngoscope, and Macintosh laryngoscope during cardiopulmonary resuscitation under cervical stabilization: a manikin study

“…Although participants had significantly less clinical experience with the AWS than with the McL before the study, the rate of successful intubations was higher with the AWS; in addition, intubation times were shorter with the AWS, and subjective evaluation as assessed by VAS score was lower. During an emergency situation, airway management is often performed by less-experienced physicians [24]. A short training on the use of the video laryngoscope will be beneficial for novice doctors in emergency airway management [25,26].…”
