Ultrasonography as an Aid in Determining Air-Filled Endotracheal Tube Cuff Position in a Critically Ill Patient: A Case Report

Endotracheal intubation is crucial for maintaining airway patency and is frequently performed in critically ill patients. However, improper placement of the endotracheal tube (ETT), particularly concerning cuff position and inflation, can lead to significant complications. Bedside airway ultrasound offers a simple, noninvasive tool to evaluate ETT cuff position and mitigate the risks associated with overinflation or malposition. Existing literature describes the visualization of the cuff inflation point with a saline-filled cuff only. In this case report, we demonstrate how an air-inflated ETT cuff can be visualized using ultrasound and correlated with computed tomography (CT) imaging to confirm correct positioning. .
