What skill is performed as a last resort for full upper airway occlusion?

• A. Needle cricothyroidotomy
• B. Endotracheal intubation
• C. Tracheostomy
• D. Laryngoscopy

Answer: (A)

When the upper airway is completely blocked, the priority is to create a direct airway that bypasses the obstruction to deliver oxygen. Needle cricothyrotomy achieves this quickly by puncturing through the cricothyroid membrane into the trachea, allowing rapid oxygen delivery (often with jet ventilation). It’s used as the last-resort maneuver because other methods that rely on passing a tube through the mouth or larynx may fail or be impossible in a blocked airway, and more definitive surgical airways take more time to establish. This approach buys time to secure a longer-term airway, such as a surgical airway, while maintaining ventilation. Laryngoscopy and endotracheal intubation aim to place a tube through the vocal cords but cannot bypass a complete upper airway obstruction quickly, and a tracheostomy, while definitive, is more time-consuming to perform.
