Awake Fiberoptic Intubation

A 48-year-old male with a history of laryngeal papillomatosis and previous difficult intubation (Cormack–Lehane Grade 3) presents for elective laryngeal microsurgery. Awake fiberoptic intubation is planned. During the procedure, the scope is advanced into the larynx and the operator notes significant subglottic narrowing with papillomatous tissue. Which of the following is the MOST appropriate immediate action to optimize visualization and reduce the risk of tube malposition?

A 52-year-old man with severe ankylosing spondylitis and limited neck mobility is scheduled for elective spinal fusion. Awake fiberoptic intubation is planned. Which investigation is most appropriate to assess the feasibility of oral fiberoptic intubation and rule out anatomical obstruction?

A 52-year-old male with severe ankylosing spondylitis and fixed cervical kyphosis is scheduled for elective spinal fusion. Awake fiberoptic intubation is planned. Which is the most common complication encountered during the procedure?

Regarding awake fiberoptic intubation (AFOI) in a patient with anticipated difficult airway, all of the following are correct EXCEPT:

A 52-year-old male with severe rheumatoid arthritis and ankylosing spondylitis presents for elective lumbar spine fusion. Clinical examination reveals severely restricted cervical spine mobility, inability to open mouth beyond 2 cm, and a Mallampati score of IV. Routine induction with propofol and succinylcholine is contraindicated due to anticipated difficult airway. The anesthesiologist decides to perform awake fiberoptic intubation. Which of the following is the MOST appropriate initial step in the preparation for this procedure?
