EDAIC Airway Management 2

Question 1

According to NAP4 and standard anesthetic guidelines, a 'difficult airway' is best defined as:

Accepted Answer

A situation where a trained anesthesiologist experiences difficulty with mask ventilation, laryngoscopy, or intubation

Answer

Tracheal intubation requiring more than two attempts by an experienced anesthesiologist

Answer

Any patient with a Mallampati score of Class III or IV

Answer

A patient with documented previous difficult intubation

Question 2

The primary indication for awake fiberoptic intubation (AFOI) is:

Accepted Answer

An anticipated difficult airway where loss of consciousness risks loss of the airway

Answer

All patients with a Mallampati Class II score

Answer

Patients requiring emergency rapid sequence induction

Answer

Any patient with a BMI greater than 35 kg/m²

Question 3

A second-generation supraglottic airway device (e.g., LMA Supreme, i-gel) differs from a first-generation device primarily by:

Accepted Answer

Incorporating a gastric drainage channel and improved oropharyngeal seal

Answer

Providing a higher oropharyngeal seal pressure exceeding 40 cmH₂O

Answer

Being designed exclusively for pediatric use

Answer

Allowing unobstructed passage of a standard endotracheal tube

Question 4

Video laryngoscopy compared to direct laryngoscopy for anticipated difficult airways:

Accepted Answer

Improves glottic visualization but tube delivery can still be challenging

Answer

Always provides a superior glottic view and always improves intubation success equally

Answer

Is contraindicated when blood or secretions are present in the airway

Answer

Consistently results in faster intubation times across all operators

Question 5

In a 'cannot intubate, cannot oxygenate' (CICO) emergency, after all supraglottic rescue attempts have failed, the correct next step is:

Accepted Answer

Emergency front-of-neck airway (eFONA) via scalpel-bougie-tube technique

Answer

Administer sugammadex and allow the patient to wake up

Answer

Repeat laryngoscopy with a different blade

Answer

Call for senior help and defer the decision

Question 6

The recommended pre-oxygenation target before RSI to maximize safe apnea duration is:

Accepted Answer

End-tidal oxygen (EtO₂) > 90% or SpO₂ > 98% maintained for at least 3 minutes

Answer

SpO₂ > 95% with standard-flow oxygen for 1 minute

Answer

SpO₂ > 99% achieved in 30 seconds only

Answer

PaO₂ > 80 mmHg confirmed on arterial blood gas

Question 7

Succinylcholine is the traditional agent of choice for RSI because:

Accepted Answer

It provides the fastest onset (~60 seconds) and shortest duration (~10 minutes) of neuromuscular blockade

Answer

It has no contraindications and is safe in all patient populations

Answer

It can be fully reversed with sugammadex at any time

Answer

It does not cause fasciculations or increase intraocular pressure
