Chapter 31. Airway Management of a Patient in a Halo-Jacket with Acute Obstruction of a Reinforced Tracheal Tube
++
++
++
Which of the following methods is NOT suitable for the exchange of an endotracheal tube in a patient with anticipated difficult airway, such as in a halo jacket?
++
++
++
++
++
B. flexible bronchoscopic intubation
++
++
C. laryngoscopy with a McCoy blade
++
++
D. airway exchange catheter
++
++
+
++
(C) Direct laryngoscopy using a Macintosh laryngoscope is known to be difficult in patients in a halo jacket.
++
++
++
A possible complication during an airway exchange is
++
++
++
++
++
B. increased abdominal pressure
++
++
C. acute respiratory failure
++
++
D. ventilator associated pneumonia (VAP)
++
++
E. acute airway obstruction
+
++
(E) The likely complications that occur during airway exchange are acute airway obstruction and failure to intubate.
++
++
++
All of the following can be tried if the tracheal tube cannot be advanced over the tube exchanger through the glottis EXCEPT
++
++
++
A. counterclockwise rotation of the tube
++
++
B. gentle pressure to force the tube through the glottis
++
++
C. lubrication of the tip of the tube
++
++
++
++
E. assist with video-laryngoscopy
+
++
(B) To avoid laryngeal injury, the endotracheal tube should never be advanced over the airway exchange catheter by force.
