Accidental Tracheal Lodging of an Endotracheal Tube Fragment during Brain MRI in a Dog: A Case Report

A 2-year-old, 5.0 kg Maltese and Poodle mix-breed dog underwent magnetic resonance imaging (MRI) for neurological assessment under general anesthesia.During transport, a disconnection from the breathing circuit led to premature awakening, causing the dog to bite through its endotracheal tube and resulting in the formation of a tracheal foreign body.Emergency bronchoscopy was performed, successfully removed the tube fragment without complications.This case highlights the risks of rapid awakening during anesthesia, which may lead to complications such as endotracheal tube fragment dislodgement and potential airway obstruction.
