laryngoscopy can use it successfully after reading this manual, without the
need for any special training. However, there are a few factors worth paying
attention to:
•
Use precurved rigid stylet
It is highly recommended to use rigid UESCOPE
®
Intubating Stylet, or
a similar one whose distal end is bent anteriorly to an angle of 45°.
This helps to make the tracheal tube conform better to the upper airway
anatomy and facilitate successful intubation, specifically when dealing
difficult airways.
•
Do not place the blade too deeply into the airway
When the device is in the optimal position the glottis should be viewed
in the central upper section of the screen. Inserting the video blade too
deeply will make it extremely difficult to pass the tracheal tube into the
glottis despite a good view. If the glottic exposure is inadequate, the
external laryngeal compression is suggested to improve the laryngeal
view.
•
Pre-heat reusable video blade to defog if necessarily
If the ambient temperature is too low, the reusable video blade or video
stylet should
not
be inserted into the patient’s mouth immediately after
the power is turned on. A one-minute preheating period, or immersing in
warm saline, are recommended to overcome the fogging issue.
After removal of the stylet from the tracheal tube, if the difficulty on advance-
ment of the tracheal tube downward into the trachea occurs, the following
measures are suggested:
•
Withdraw the video laryngoscope blade 1–2 cm backwards to allow the
glottis draw down.
•
Reduce the upward lifting force of the video laryngoscope so that the
patient’s head will be returned to the neutral position and the tracheal
tube tip can be away from the anterior tracheal wall.
