BOULDER, Colo. (Nov. 11, 2008) – A two-year randomized study just published in the peer-reviewed journal CHEST (November 2008) demonstrates that continuous aspiration of subglottic secretions (CASS) [i] significantly reduced antibiotic usage in post-cardiac surgery patients. CASS was also found to reduce the incidence of Ventilator-Associated Pneumonia (VAP), ICU length of stay, and duration of mechanical ventilation in patients intubated for more than 48 hours.
