Summary

This study was designed to see if a harmless marker (quinine) placed in the mouth could show up in lung secretions, indicating that fluid is leaking past the breathing tube's cuff. It aimed to help detect aspiration in critically ill patients on ventilators. However, the study was withdrawn before enrolling any participants, so no results are available.
