Ultrasound can be used to reveal accumulation of secretions in the subglottic space of intubated patients. (A), which was produced using a 6- to 13-MHz linear array ultrasound probe (SonoSite, USA) and a long-axis lateral approach with the head rotated 20 to 30° to the opposite side,1 shows a sonolucent area that appeared after injecting 3 ml of saline through a subglottic catheter above the endotracheal tube (ETT) cuff, which had been insufflated with air. The sonolucent area disappeared after the injected saline had been suctioned out (B). Dynamic changes in sonolucency during injection followed by aspiration of saline via a subglottic catheter are shown (Supplemental Digital Content 1, http://links.lww.com/ALN/C472). Aspirating and reinjecting saline into the subglottic space of another intubated patient with supracuff secretions also revealed these phenomena (Supplemental Digital...
