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.
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).
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 ...
A gastric feeding tube (G-tube or "button") is a tube inserted through a small incision in the abdomen into the stomach and is used for long-term enteral nutrition. One type is the percutaneous endoscopic gastrostomy (PEG) tube which is placed endoscopically.
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.

Nasogastric tube (Levin type) Abraham Louis Levin (December 16, 1880 – September 15, 1940) was an American physician and the inventor of the Levin Tube, which is still widely used for duodenal drainage after surgery and for management of trauma patients. [1] This procedure is known as nasogastric intubation.
