EDAIC Airway Management 4

Question 1

Which videolaryngoscope blade geometry provides the best glottic view in a patient with limited mouth opening (<25 mm)?

Accepted Answer

Hyperangulated blade (e.g., GlideScope LoPro)

Answer

Hyperangulated blades require less mouth opening and achieve superior glottic views in restricted-aperture scenarios compared to Macintosh-geometry videolaryngoscope blades.

Question 2

In the 'can't intubate, can't oxygenate' (CICO) scenario, what is the recommended first-line surgical airway technique according to DAS guidelines?

Accepted Answer

Scalpel-finger-bougie cricothyroidotomy

Answer

The scalpel-finger-bougie technique is the DAS-recommended first-line approach for surgical airway in CICO because it is fast, reliable, and minimizes failed attempts compared to needle or percutaneous methods.

Question 3

A patient undergoing awake fibreoptic intubation develops sudden apnoea after topical airway anaesthesia. What is the most likely cause?

Accepted Answer

Systemic absorption of lidocaine causing CNS toxicity

Answer

Excessive systemic absorption of topical lidocaine, especially with high doses or mucosal inflammation, can cause CNS toxicity manifesting as seizures or apnoea.

Question 4

Which anatomical landmark defines the correct position for needle cricothyroidotomy?

Accepted Answer

Midpoint of the cricothyroid membrane in the midline

Answer

The cricothyroid membrane lies between the thyroid and cricoid cartilages in the midline, and its midpoint is the target for needle or surgical cricothyroidotomy.

Question 5

During rapid sequence induction, which agent provides the fastest onset of complete neuromuscular blockade for intubating conditions?

Accepted Answer

Succinylcholine 1.5 mg/kg

Answer

Succinylcholine 1.5 mg/kg achieves complete neuromuscular blockade within approximately 60 seconds, faster than any non-depolarising agent at standard doses.
