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, or removing stomach contents. NG tubes are commonly used in patients who cannot eat by mouth due to surgery, illness, or other medical conditions. The procedure for placing a nasogastric tube is typically performed by a healthcare professional. The tube is measured for the correct 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 accidental placement in the lungs.
