Gastric suction?
by

1 Answer

Answer :

DefinitionGastric 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 suctionHow 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 c
