Definition: A nasogastric (NG) tube is a flexible tube of rubber or plastic that is passed through the nose, down through the esophagus, and into the stomach. It can be used to either remove or add substances from the stomach.
An NG tube might be put in place for several reasons, including:
- administering nutrients or medication
- removing liquids or air from the stomach
- adding contrast to the stomach for x-rays
- protecting the bowel after surgery or during bowel rest
