Does a feeding nasogastric tube cause hypoxaemia?

Abstract

The use of feeding nasogastric tube has been very beneficial in management of sick infants to ensure optimal intake but is not without untoward effects. Persistent hypoxaemia is not well known to be associated with nasogastric tube feeding. We report two cases of persistent hypoxaemia in tube-fed patients with resolution on removal. Clinicians need to have a high index of suspicion for possible association between nasogastric tube feeding and persistent hypoxaemia after excluding common causes of hypoxaemia. Regular pulse oximetry and prompt removal of the tube is recommended once patient can take considerable quantity of feeds and fluid orally.
