A case is reported of a stroke patient who aspirated his nasopharyngeal airway, resulting in coughing and desaturation. After iv propofol and topical anaesthesia to the oropharynx and hypopharynx, it was seen on laryngoscopy to be within the trachea but could not be retrieved with Magill forceps. Instead, his doctors inserted a well lubricated 14 Fr foley catheter through the lumen of the tube, inflated the balloon, and pulled it out.
