Segment:1 Device.
The Shikani Optical Stylet is a fiber optic scope in a semi-rigid malleable stylet that can accommodate tracheal tubes greater than 5.5 millimeter internal diameter. Tracheal fixation on the stylet shaft is achieved by a movable tube stop adapter. The fiber optic bundles deliver the image to a proximal eyepiece which is compatible with standardized camera adapters.
Lighting is supplied from a battery handle containing a 6-volt halogen bulb, or using an adapter via a Green specification fiber optic laryngoscope handle.
Segment:2 Preparation.
To prevent fogging, the device should be prepared with an anti-fogging solution, warm water immersion, or warming the device using an external source of heat, such as the bear 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. The Shikani stylet can be used alone or in conjunction with direct laryngoscopy. If it is used with a laryngoscope, the distal angulation should not be more than 30 degrees.
Segment:3 Technique.
It is our preference to use the Shikani stylet together with a laryngoscope. Following denitrogenation and with the patient placed in a sniffing position, the laryngoscope is inserted into the vallecula to elevate the epiglottis.
The Shikani stylet and tracheal tube assembly can then be inserted in a midline position. Once at the laryngeal aperture, the tracheal tube can be advanced off the stylet through the cords. Tube placement should be confirmed using end tidal CO2 and auscultation.
Segment:4 Trouble Shooting.
Fogging of the lens can occur. Meticulous stylet preparation is needed by performing an anti-fogging maneuver and ensuring the oral pharynx has been suctioned prior to tracheal 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 tracheal 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 Shikani stylet is a fiber optic scope in a semi-rigid, malleable stylet that can be used to direct the tracheal tube through the glottic opening under vision.
However, in order to have a successful intubation, careful preparation of the device and regular practice are necessary.
