A nasogastric tube (NG tube) is a flexible tube inserted through the nose, down the esophagus, and into the stomach. It is used for various medical purposes, including providing nutrition, administering medications, and removing stomach contents. NG tubes are often utilized in patients who cannot eat by mouth due to surgery, illness, or other conditions. The procedure for placing an NG tube is typically performed by a healthcare professional. The tube is measured for proper length, lubricated, and gently inserted while the patient swallows to facilitate placement. Proper care and monitoring are essential to prevent complications, such as nasal irritation or tube displacement.
