The pathophysiology linking OSAS to cor pulmonale is:
Hyperventilation-induced alkalosis
Repetitive hypoxemia raising pulmonary pressures
Central nervous dysfunction only
Tracheal narrowing alone
A 45-year-old with Mallampati Class 4 airway is scheduled for elective tonsillectomy. Which is the most appropriate step?
Proceed with direct laryngoscopy under deep inhalational anesthesia
Use blind nasal intubation as first choice
Rely on LMA without backup devices
Plan for awake fiberoptic intubation under topical anesthesia
A 5-year-old with snoring, daytime somnolence, and obesity is evaluated. The STBUR questionnaire is positive. What would be your next step?
Proceed directly to surgery
Cancel surgery
Schedule polysomnography or DISE based on availability
Rely only on physical exam
For a child with severe OSAS (AHI > 10, O₂ nadir < 80%), you plan:
Postoperative ICU admission for monitoring
Day-case discharge
No special monitoring
Discharge after 30 min PACU stay
Which induction technique aligns with the goal of rapid emergence in pediatric adenotonsillectomy?
Inhalational induction with sevoflurane and N₂O
Intravenous propofol bolus avoiding long-acting agents
High-dose midazolam premedication
Ketamine infusion for deep sedation
Extubation awake versus deep in pediatric ENT surgery yields:
Similar airway complication rates; choose based on surgical field and reflex return
Always safer deep
Always safer awake
Depends on steroid use only
A child vomits blood-tinged fluid post-tonsillectomy. First action is:
Administer high-flow N₂O
Increase TIVA rate
Insert orogastric tube to decompress stomach
Oral NSAID bolus to reduce inflammation
During mastoidectomy, you maintain mean arterial pressure at 10% below baseline to:
Prevent pneumothorax
Enhance evoked potentials
Increase cardiac output
Optimize surgical field by reducing bleeding
For foreign-body aspiration into right mainstem bronchus, choosing spontaneous ventilation over controlled ventilation may reduce:
Cough reflex
Bronchospasm
Oxygenation
Distal migration of the object via ball-valve effect
Which fluid strategy best prevents dehydration without causing airway edema?
Isotonic crystalloid intraoperatively, early postop encouragement of clear fluids
Dextrose 5% only
Hypertonic saline bolus
Restricting all fluids
