Best Practices for the Safe Insertion and Maintenance of a Nasogastric Tube in Acute Care and Nutritional Support
A nasogastric tube is a thin, flexible tube passed through the nose into the stomach to provide nutrition or remove gastric contents.
The insertion of a nasogastric (NG) tube is a common yet critical procedure in both emergency and long-term care settings. In group discussions among nursing staff, the primary focus is always "placement verification." Because of the risk of the tube entering the lungs (bronchial placement), clinicians must use multiple methods to ensure it is in the stomach. While auscultation—listening for an air bolus—was common in the past, current best practices mandate pH testing of gastric aspirate or, most reliably, an X-ray confirmation.
NG tubes serve two main purposes: "decompression" and "enteral feeding." Decompression involves removing air or fluid from the stomach in cases of bowel obstruction or after major surgery. Feeding involves delivering liquid nutrition directly to the stomach for patients who cannot swallow safely. Discussion often revolves…
