title: An unusual instance of stridor: airway obstruction from a nasogastric tube knot in a 1-month old infant.
abstract: We report a 1 month old infant with a spontaneously knotted nasogastric tube. Attempted removal of the nasogastric tube was unsuccessful, prompting further investigation. Plain radiographs revealed a large, multi-looped knot impacted in the nasopharynx and oropharynx. The tube was subsequently removed through the mouth under general anesthesia without complication, revealing a large, impressive knot of the distal end of the nasogastric tube.
