Knotting of nasogastric tube around a nasotracheal tube: An unusual cause of hypercapnia in a 3-month-old infant.

A 3-month-old boy was admitted to the intensive care unit because of septic shock; he required immediate intubation and placement of a nasogastric tube. A confirmatory chest radiograph showed that the nasogastric tube was looping in the hypopharynx and needed to be repositioned. During removal of the nasogastric tube, the infant experienced hypercapnia and respiratory distress. These complications were due to looping and knotting of the nasogastric tube around the nasotracheal tube.
