The Visualization of a Foreign Body in a Patient's Subglottic Region Using Point-of-Care Ultrasonography.

Point-of-care ultrasonography is a real-time dynamic examination that is useful for evaluating the location of foreign bodies in a patient's gastrointestinal tract and soft tissue. In particular, it is useful for identifying radiolucent foreign bodies that are difficult to visualize using routine x-ray examinations. This case study describes the visualization of a radiolucent foreign body in a patient's subglottic region using point-of-care ultrasonography.
