A nasogastric tube (NG tube) is a flexible tube that is inserted through the nose and down the throat into the stomach. It is commonly used in medical settings to deliver nutrients, medications, or fluids directly into the stomach or to remove excess fluids or gases from the stomach. Nasogastric tubes are also used for diagnostic purposes, such as collecting samples of stomach contents for analysis. Proper placement and care of a nasogastric tube are essential to prevent complications and ensure effective treatment. Research in this area focuses on advancements in tube design, insertion techniques, patient comfort, and outcomes related to the use of nasogastric tubes in various medical conditions.
