Summary

This study tested whether a negative pressure suction device placed in the throat could reduce aspiration (food or liquid entering the airway) during swallowing exams in people with severe swallowing problems. Only one person participated, and the device was inserted through an existing gastrostomy tube. The goal was to see if suction could safely lower the risk of aspiration.

Active substance: Negative pressure suction catheter (Foley catheter placed through gastrostomy site)
What this could lead to: If it works, this could offer a new way to reduce aspiration risk during swallowing for patients with severe swallowing problems.
What could go wrong: This was a very small study with only one participant, so results may not apply to others. The device requires a gastrostomy tube, limiting who can use it.
