Gastric suction is done to empty the contents of the stomach. The purpose of gastric suction is usually for tests, or for removal of materials such as poisons.
A tube is inserted through the nose or mouth, down the esophagus (food pipe), and into the stomach. Sometimes a numbing medicine may be given to minimize irritation and gagging as the tube is being inserted.
Stomach contents can be removed using suction immediately, or after spraying water through the tube.
How to prepare for the test:
In an emergency setting, such as when a patient has swallowed poison or is vomiting blood, no preparation is needed for gastric suction. When it is done for the purpose of testing, your doctor may ask you not to eat overnight, or stop taking certain medications.
How the test will feel:
You may feel a gagging sensation as the tube is passed.
