Segment:1 Device.
The Clarus Video System is an optical stylet with a video screen mounted on the handle. The 3" LCD screen can be tilted using a thumb control. A CMOS image sensor is located at the distal end of the stylet, which is detachable from the handle for cleaning and sterilization purposes. The handle also houses a rechargeable battery. The stylet shaft is semi-malleable and has a shaft-mounted tube stop adapter to enable optimal placement of the stylet tip just within the distal end of the endotracheal tube.
Segment:2 Preparation.
To prevent fogging, the stylet should be prepared with an antifogging solution, warm water immersion, or warming the device using an external source of heat such as the Bair Hugger. The stylet should also be lubricated before inserting into a tracheal tube. To remove blood and secretions, the hypopharynx should be suctioned prior to intubation. Like other intubating stylets, the Clarus Video System can be used alone or in conjunction with direct laryngoscopy.
Segment:3 Technique.
It is our preference to use the Clarus Video System together with a laryngoscope. The patient should be placed in the sniffing position and should be well oxygenated prior to intubation. The laryngoscope is inserted into the vallecula to elevate the epiglottis. The Clarus Video System and the trachael tube assembly can then be inserted in a midline position and carefully placed just beneath the epiglottis under direct vision.
The practitioner should then seek the glottic view through the video screen. The vocal cords should be readily seen. Once at the laryngeal aperture, the tracheal tube can be advanced off the stylet through the cords. Two placements should be confirmed using end-tidal CO2 and auscultation.
Segment:4 Trouble Shooting.
Fogging can occur. Meticulous stylet preparation is needed by performing an antifogging maneuver and ensuring the oral pharynx has been suctioned prior to intubation.
Despite a good glottic view, advancing the tracheal tube into the trachea over the stylet can be difficult sometimes. To avoid this, the tube should be immersed in warm saline solution prior to its use to reduce its stiffness and memory of its natural curvature. In addition, reverse loading of the trachael tube onto the stylet may minimize the tendency of the tube tip to bend anteriorly while advancing the tube into the trachea.
With reverse loading, the tip of the tracheal tube is more likely to be directed down the lumen of the trachea, making it easier to advance.
Segment:5 Summary.
The Clarus Video System is a malleable optical stylet with a video display on the handle. It can be used to direct the tracheal tube through the glottic opening under indirect vision. However, in order to have a successful intubation, careful preparation of the device and regular practice are necessary.
