What does CASS stand for?

• A. Continuous aspiration of subglottic secretions
• B. Continuous airway suction of subglottic secretions
• C. Constant aspiration of subglottic secretions
• D. Continuous aspiration of subglottic saliva

Answer: (A)

Continuous aspiration of subglottic secretions is a technique used in intubated neonates to remove secretions that pool above the endotracheal tube cuff. By continuously aspirating these secretions, it helps prevent microaspiration into the lower airway, reducing the risk of ventilator-associated pneumonia. This is typically done with an endotracheal tube that has a dedicated subglottic suction lumen delivering low continuous suction to the space above the cuff. The other phrasings aren’t the standard way this is described: “airway suction” is a broader term and doesn’t specify the subglottic space; “constant” isn’t the preferred descriptor compared to “continuous”; and “saliva” isn’t the terminology used for this technique, which targets subglottic secretions above the cuff.
