In managing a laryngospasm during sedation, which intervention is the reversal technique recommended?

Laryngospasm during sedation is an abrupt, protective closure of the vocal cords that can rapidly compromise the airway. The fastest, least invasive way to try to break that spasm is a trapezius pinch. This maneuver stimulates the sympathetic nervous system via a brief, reflex response, which can help relax the laryngeal muscles and open the airway. It’s quick to perform, requires no equipment, and can buy time to advance other airway measures if needed. In practice, you start with basic airway support for a sedated child: ensure 100% oxygen delivery, perform a jaw thrust, use continuous positive airway pressure as appropriate, and suction if secretions are contributing. If the laryngospasm persists, you escalate to pharmacologic or definitive airway steps, such as using a short-acting muscle relaxant (e.g., succinylcholine) after confirming adequate oxygenation, or proceeding with deeper anesthesia or airway instrumentation as indicated. Other options are not primary reversal techniques for laryngospasm. Atropine does not reverse the spasm; it’s used for cholinergic effects or bradycardia in other contexts. Using a laryngoscope with suction can help clear secretions but does not directly reverse the spasm. Cricotracheostomy is an invasive rescue procedure for complete airway obstruction when less invasive measures have failed, not a first-line reversal for laryngospasm.
