Nasogastric Tube

A nasogastric, or NG tube, is a thin, flexible tube used in some medical procedures.

Physical Appearance
An NG tube can made of rubber or plastic and vary in color, length, and size. It has small black numbers that skipcount by five or ten on each side, as well as little black lines. It can also have a hub attached to facilitate procedures involving syringes (such as stomach pumping).

Purposes
An NG tube is used by a doctor or nurse to provide food, water, and medicine to a patient who can't feed themselves. It can also be used for removing a patient's stomach contents.

How It's Used
The tube is passed through the nose, down the throat, and into the esophagus before finally ending up in the stomach. Fluids are then injected into the tube, which carries them directly into the patient's stomach.

Chapter 8: Tsunade
Tsunade inserts an NG tube into Zoku's right nostril when the latter has an eating disorder. She leaves the tube in his nose afterward, but greases it with lotion before inserting it so as not to irritate his nostril and throat. Tsunade then secures the tube into place with medical tape and restrains Zoku's hands so he can't remove it.
