Gastric suction is a procedure that empties the contents of the stomach. It may be done for tests, or to remove materials such as poisons.
Alternative NamesGastric lavage; Stomach pumping; Nasogastric tube suction
How the test is performedA tube is inserted through the nose or mouth, down the food pipe (esophagus), and into the stomach. Sometimes you may get a numbing medicine to reduce irritation and gagging as the tube is being inserted.
Stomach contents can be removed using suction right away, or after spraying water through the tube.
How to prepare for the testIn an emergency, such as when a patient has swallowed poison or is vomiting blood, no preparation is needed for gastric suction. When it is done for testing, your doctor may ask you not to eat overnight, or to stop taking certain medications.
How the test will feelYou may feel a gagging sensation as the tube is passed.
Why the test is performedThis test may be performed for several different reasons, including:
- Removing poisons, toxic materials, or overdosed medications from the stomach
- Cleaning the stomach before an upper endoscopy (EGD) in someone who has been vomiting blood
- Collecting stomach acid for tests
- Relieving pressure in someone with a blockage in the intestines
There is a very small risk of the tube being accidentally placed into the airway instead of the esophagus.
Other small risks include the following:
- Aspiration of gastric contents
- Perforation of the esophagus
- Minor bleeding

What is a Salem sump tube?
It is a two lumen tube that removes gastric contents. One lumen is a suction and the other is an air vent. The air vent never clamps or connects to the suction.
Why is gastric aspirate orange when there is an NG tube to suction?
Gastric aspirate can appear orange when an NG tube is in place due to the presence of bile, which can mix with gastric contents. This can occur if there is reflux of duodenal contents into the stomach, especially if the stomach is empty or if there is increased gastric motility. Additionally, certain foods or medications can also contribute to the discoloration of the aspirate.
What is the rationale of nasogastic low intermitten suction?
Nasogastric low intermittent suction is employed to manage conditions like bowel obstruction or ileus by removing gastric contents and reducing stomach distention. This technique helps alleviate symptoms such as nausea and vomiting while promoting comfort and facilitating recovery. Additionally, it allows for the assessment of gastrointestinal function and can help prevent complications associated with retained gastric secretions. The intermittent nature of the suction minimizes mucosal irritation and promotes mucosal healing.
How is the collection of a sample of gastric juice collected for biochemical analysis?
The collection of a gastric juice sample for biochemical analysis typically involves a procedure called gastric aspiration. This is performed using a nasogastric tube, which is inserted through the nose, down the esophagus, and into the stomach. Once in place, the tube is used to suction out gastric contents, which can then be collected for analysis. The procedure may be done after fasting and is often guided by a healthcare professional to ensure accuracy and minimize discomfort.
