The Airtraq® (Prodol Meditec SA, Vizcaya, Spain) is a single use device which consists of an anatomically shaped laryngoscope with a built-in tube channel. A battery operated light emitting diode is present at the tip and provides the illumination. The laryngeal view is transmitted to the proximal viewfinder through a combination of lenses and prisms. Facilities are also available for transmitting the image to an integrated monitor or an external wireless monitor.

Prior to RSI, equipment and team preparation is paramount. A trained anaesthetic assistant should be available and ideally a second clinician whose role is to administer drugs and to monitor vital signs. A team member should be designated to perform thoracostomy should a tension pneumothorax become evident. In the event of cervical spine control being necessary, any cervical collar should be opened or removed and replaced with manual in-line stabilization by another team member. All equipment should be checked daily and again prior to casualty arrival. Minimum equipment immediately available includes: Self-inflating bag and correctly sized facemask.Two sizes of laryngoscope (MAC 3 and 4 for adults).Appropriately sized endotracheal tubes.Failed/difficult intubation equipment.Bougie.Oropharyngeal and nasopharyngeal airways.Laryngeal mask airway (ideally second generation e.g. ProSeal®, iGel®).Alternative laryngoscope (e.g. AirTraq®, Glidescope® if available).Surgical airway equipment.Working suction.Monitoring including end-tidal CO2, ECG, non-invasive blood pressure (NIBP) and SpO2.
Laryngoscopes for difficult airway scenarios: a comparison of the available devices
Published in Expert Review of Medical Devices, 2018
Airtraq (Prodol Meditec S.A., Vizcaya, Spain) is a single-use, disposable indirect optical laryngoscope with an eyepiece on the handle which can be attached to a camera to allow video viewing on a wireless monitor or smartphone [43]. The smallest device size, 0, allows intubation with a tube with the internal diameter of 4.0–5.5. The blade consists of two parallel channels: one guiding the endotracheal tube, and the other with the optical and anti-fogging system. The image is derived from close to the tip of the blade. The optical channel is made of a series of lenses, prisms, and mirrors, allowing for a proper visualization of the anatomical structures that are in the reach of the tip of the device [44]. The Airtraq videolaryngoscope is inserted to the mouth in the midline and passed into the vallecula. For an effective intubation to be achieved, the image of the vocal cords must be located at the center of the display, and the manufacturers describe a ‘back-and-up’ maneuver to perform this. Besides the aforementioned anti-fog system, the laryngoscope is equipped with a low-temperature battery-powered light source [45].

The Airtraq laryngoscope is an anatomically shaped, optical laryngoscope. It is a single-use device and is made up of reusable optical components which feature an antifogging effect, disposable blades and eyecup, a docking station, and an optional camera. The battery can be used approximately for 90 min after fully charged. Furthermore, light indicators are presented at the tip of the blade showing the status of battery charge and service life. The optics can be protected from patient contact by the disposable blades and eyecup. The blades have two parallel conduits for the optical and guiding channels. Different sizes of blades are available to work with various types of endotracheal tubes for adult, pediatric, and neonatal use. The docking station is used for charging the battery and the Wi-Fi camera and for displaying the service life of the optical system. Since the Airtraq has two viewing systems, the patient’s airway can be looked through the eyecup or through the Wi-Fi camera.

The Totaltrack VLM has been used for securing the airway for emergent surgery in uncooperative patients with cervical masses causing airway distortion and trismus [67,68]. It has also been used as a rescue device after failed ventilation and tracheal intubation with other devices, such as Airtraq or LMA Fastrach in emergent difficult airways with satisfactory results [69–71].
