What strategies help minimize aspiration risk during procedural sedation?

• A. Do not fast
• B. Adequate fasting, airway protection when indicated, careful choice of medications, head-up or lateral recovery position, and readiness for suction
• C. Always use deep anesthesia
• D. Avoid airway protection

Answer: (B)

Minimizing aspiration risk during procedural sedation relies on protecting the airway and reducing the amount and consequence of gastric contents in the airway if regurgitation occurs. Adequate fasting lowers gastric volume and acidity, so if regurgitation happens there’s less material to aspirate and less potential lung injury. Airway protection when indicated means assessing each patient’s risk and using appropriate devices or techniques to secure the airway when protection is needed, recognizing that sedation can blunt reflexes that normally prevent aspiration. Careful choice of medications means selecting agents and dosing that achieve the needed level of sedation with the least impairment of protective airway reflexes and gastric motility, avoiding combinations that overly depress respiration or swallowing. A head-up or lateral recovery position helps keep the airway clearer during emergence and allows any potential vomitus to drain away from the lungs. Being ready for suction ensures that secretions or any aspirated material can be promptly cleared, limiting exposure of the airways to harmful material. Other approaches that ignore fasting, avoid airway protection, or rely on deep anesthesia without airway safeguards do not address these protective strategies and can increase aspiration risk.
