CAA CAA Anesthesia Techniques & Airway Management 3

Question 1

Which inhalation induction agent is preferred for pediatric patients due to its non-pungent, sweet odor?

Accepted Answer

Sevoflurane

Answer

Sevoflurane is the preferred inhalation induction agent in pediatrics because of its pleasant, non-irritating smell and low blood-gas solubility coefficient allowing rapid induction.

Question 2

During a failed airway situation, the 'can't intubate, can't oxygenate' (CICO) scenario is definitively managed with:

Accepted Answer

Emergency front-of-neck access (cricothyrotomy)

Answer

When all intubation attempts and supraglottic airway insertions fail and oxygenation cannot be maintained, emergency surgical cricothyrotomy provides a definitive rescue airway.

Question 3

Awake fiberoptic intubation is the technique of choice for anticipated difficult airway management primarily because:

Accepted Answer

It preserves the patient's spontaneous breathing and airway reflexes until the airway is secured

Answer

Awake fiberoptic intubation allows the patient to maintain spontaneous ventilation and protective airway reflexes, providing a safety margin that disappears after induction of anesthesia.

Question 4

Postoperative nausea and vomiting (PONV) prophylaxis using ondansetron works by blocking:

Accepted Answer

Serotonin 5-HT3 receptors in the gut and chemoreceptor trigger zone

Answer

Ondansetron is a selective 5-HT3 receptor antagonist that blocks serotonin signaling in both the gastrointestinal tract and the chemoreceptor trigger zone, reducing PONV.

Question 5

The primary advantage of total intravenous anesthesia (TIVA) with propofol-remifentanil over volatile anesthetic-based anesthesia in patients with a history of malignant hyperthermia susceptibility is:

Accepted Answer

Avoidance of triggering agents (volatile anesthetics and succinylcholine)

Answer

TIVA avoids volatile halogenated anesthetics and succinylcholine — the two known triggers of malignant hyperthermia — making it the recommended technique for MH-susceptible patients.
