“…Alternatively, the device can be inserted like a Guedel airway upside down and then rotated 180° in the mouth. [40] Inability to successfully pass the ETT may also occur despite view of the glottis and a bougie may first be passed through the loaded ETT into the larynx before railroading the tube. This is particularly useful if the blade length is not sufficient to pass posterior to the epiglottis, which can obstruct the path of the tube.…”

The incidence of difficult direct intubation in the intensive care unit (ICU) is estimated to be as high as 20%. Recent advances in video-technology have led to the development of video laryngoscopes as new intubation devices to assist in difficult airway management. Clinical studies indicate superiority of video laryngoscopes relative to conventional direct laryngoscopy in selected patients. They are therefore an important addition to the armamentarium of any clinician performing endotracheal intubation. We present a practical review of commonly available video laryngoscopes with respect to design, clinical efficacy, and safety aspects relevant to their use in the ICU.

“…The intubation procedure for the AWS is explained in four stages-insertion, rotation, elevation, and intubation [10]. We propose fifth stage, ''confirmation'' of the anatomical structure, for safe intubation with this device.…”

Displacement of the epiglottis during intubation with the Pentax-AWS Airway Scope

The Pentax-AWS system is a rigid indirect video laryngoscope with integrated tube guidance. Complications associated with this device are not well understood. We report two cases of epiglottis malposition during intubation with the Pentax-AWS. The standard technique of using the Pentax-AWS system involves direct elevation of the epiglottis for exposure of the vocal cords. The blade tip should be passed posterior to the epiglottis for laryngeal exposure, but pressure on the anterior surface of the epiglottis by the tip can rarely happen even during the correct maneuver. Although the Pentax-AWS provides clear images of the airway structures, it is sometimes difficult to observe the epiglottis continuously because the camera is located beneath the blade tip. Consequently, the view of the epiglottis from the camera may be impeded by the blade tip and may result in undiagnosed epiglottis malposition. The AWS's structural feature and its approach to the larynx can be associated with increased chance of unexpected epiglottis folding. It is particularly important to confirm normal position of the epiglottis during withdrawal of the device to prevent this complication.
