A wide-bore soft plastic or rubber tube is pushed down the gullet (oesophagus) into the stomach, the end held high, and water run in through a funnel. The end of the tube is then lowered so that the washings drain out. This process is repeated until the returning water is clear.

gastric lavage, or irrigation of the stomach, is usually done to remove ingested poisons. The solutions used for gastric lavage are physiological saline, 1% sodium bicarbonate, plain water or a specific antidote for the poison.

The solution is removed by siphonage; when the funnel is lowered, the fluid flows out, bringing with it the contents of the stomach. Called also gavage.
