A medical procedure using a tube inserted through the nose into the stomach to remove air, fluid, or food contents, relieving pressure and distension. This technique is commonly used to treat bowel obstruction or prevent aspiration.
From Latin 'nasus' meaning 'nose' + Greek 'gaster' meaning 'stomach' + Latin 'decomprimere' meaning 'to relieve pressure.' The technique developed in the early 20th century as understanding of gastrointestinal physiology advanced and flexible tubing became available.
A single nasogastric tube can remove up to several liters of fluid and gas from a distended stomach, providing almost immediate relief from nausea and abdominal pain! The procedure is so effective that patients often feel dramatically better within minutes of insertion.
