Nasogastric intubation is a medical process involving the insertion of a plastic tube (nasogastric tube or NG tube) through the nose, down the esophagus, and down into the stomach. Orogastric intubation is a similar process involving the insertion of a plastic tube (orogastric tube) through the mouth. [1] Abraham Louis Levin invented the NG tube.
The gold standard for checking and confirming NG tube placement is to aspirate some fluid and check the pH level. The pH level of gastric secretions should be between 4-6. A secondary way to confirm placement (no longer the gold standard) is to auscultate using a stethoscope by placing the diaphragm of the stethoscope over the stomach and ...
There are dozens of conditions that may require tube feeding (enteral nutrition) to prevent or treat malnutrition. Conditions that necessitate feeding tubes include prematurity, failure to thrive (or malnutrition), neurologic and neuromuscular disorders, inability to swallow, anatomical and post-surgical malformations of the mouth and esophagus, cancer, Sanfilippo syndrome, and digestive ...
A man with a nasogastric tube allowing food and medicine to be delivered through the nose and straight to the stomach. Enteral administration may be divided into three different categories, depending on the entrance point into the GI tract: oral (by mouth), gastric (through the stomach), and rectal (from the rectum).
For example, nasogastric (NG) tubes inserted through the nose and into the stomach can help remove stomach contents for patients who have a blockage further along in their gastrointestinal tract. After surgery, drains can be placed to remove blood, lymph, or other fluids that accumulate in the wound bed.
The tube may be difficult to position, particularly in an unwell patient, and may inadvertently be inserted in the trachea, hence endotracheal intubation before the procedure is strongly advised to secure the airway. The tube is often kept in the refrigerator in the hospital's emergency department, intensive care unit and gastroenterology ward.

This position is frequently used when feeding a patient (especially one on feeding precautions), for radiology, needing to take a specific type of x-ray at the bedside, (at times) when a breathing treatment is being given to the patient, when the patient is having difficulty breathing, for nasogastric tube insertion, for dependent drainage ...
