What are best suctioning practices before and during emergency endotracheal intubation?

• A. Use large-bore suction to clear secretions; suction briefly and carefully to avoid mucosal injury; adjust power settings.
• B. Always suction with maximum suction power for a long duration.
• C. Avoid suction until after intubation.
• D. Use the smallest suction catheter possible.

Answer: (A)

Clearing the airway efficiently before and during emergency intubation hinges on using an appropriately sized suction catheter to quickly remove secretions and debris, while protecting the patient from hypoxia and trauma. A large-bore suction catheter is best for rapidly clearing thick secretions, blood, or vomitus, which helps you see the airway and reduces the risk of aspiration during intubation. Suctioning should be brief and intermittent rather than a prolonged pull; short passes allow you to reoxygenate between attempts and limit the amount of time the patient is without ventilation. Negative pressure should be set to a level that clears material without causing tissue injury or significant desaturation, adapting to the situation as needed. This approach balances effective airway clearance with the need to maintain oxygenation and minimize mucosal injury.

Using maximum suction power for a long duration risks hypoxemia and mucosal injury, so it’s not appropriate. Suctioning should be performed before intubation to improve visualization and reduce aspiration risk, not avoided until after intubation. A very small catheter can make clearing thick secretions take longer and may be insufficient for rapid clearance.
