Which inhalation induction agent is preferred for pediatric patients due to its non-pungent, sweet odor?
Answer: Sevoflurane
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.
During a failed airway situation, the 'can't intubate, can't oxygenate' (CICO) scenario is definitively managed with:
Answer: Emergency front-of-neck access (cricothyrotomy)
When all intubation attempts and supraglottic airway insertions fail and oxygenation cannot be maintained, emergency surgical cricothyrotomy provides a definitive rescue airway.
Awake fiberoptic intubation is the technique of choice for anticipated difficult airway management primarily because:
Answer: It preserves the patient's spontaneous breathing and airway reflexes until the airway is secured
Awake fiberoptic intubation allows the patient to maintain spontaneous ventilation and protective airway reflexes, providing a safety margin that disappears after induction of anesthesia.
Postoperative nausea and vomiting (PONV) prophylaxis using ondansetron works by blocking:
Answer: Serotonin 5-HT3 receptors in the gut and chemoreceptor trigger zone
Ondansetron is a selective 5-HT3 receptor antagonist that blocks serotonin signaling in both the gastrointestinal tract and the chemoreceptor trigger zone, reducing PONV.
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:
Answer: Avoidance of triggering agents (volatile anesthetics and succinylcholine)
TIVA avoids volatile halogenated anesthetics and succinylcholine — the two known triggers of malignant hyperthermia — making it the recommended technique for MH-susceptible patients.
Transversus abdominis plane (TAP) blocks provide analgesia primarily to which anatomical region?
Answer: Anterior abdominal wall from T6 to L1 dermatomes
TAP blocks deposit local anesthetic between the internal oblique and transversus abdominis muscle layers, blocking the thoracolumbar nerves that supply the anterior abdominal wall (T6–L1).
