What is the initial management for laryngospasm during sedation?

• A. Immediate 100% oxygen, jaw thrust, and attempt to relieve obstruction; if unresolved, consider pharmacologic airway relaxation and advanced airway support.
• B. Administer sedatives
• C. Remove oxygen
• D. Ignore and continue

Answer: (A)

This question tests the immediate airway management of laryngospasm during sedation. The priority is to rapidly restore oxygenation and relieve the vocal cords’ reflexive closure with simple, effective maneuvers before moving on to medications or definitive airway procedures. Start with 100% oxygen and actively open the airway. A jaw thrust helps move the tongue and soft tissues away from the laryngeal inlet, reducing obstruction. If needed, use suction to clear secretions and provide ventilation with a bag-valve mask delivering high-concentration oxygen, continuing to monitor air exchange and oxygen saturation. These steps aim to break the spasm and re-establish a patent airway without delaying ventilation. If the obstruction persists despite these measures, escalate to pharmacologic airway relaxation and advanced airway support. This often means administering a rapid-acting muscle relaxant (such as a small dose of a neuromuscular blocker) to relieve the laryngospasm and then securing the airway with an endotracheal tube or a supraglottic device as appropriate. Why the other options don’t fit: sedatives would worsen airway obstruction by suppressing protective reflexes; removing oxygen removes the very stimulus needed to prevent hypoxemia; ignoring the problem risks progression to severe hypoxemia or cardiac arrest. The correct approach is to prioritize oxygenation and airway maneuvers first, then escalate if needed.
