gastric lavage

Stomach washout. This is done to remove or dilute drugs or non-corrosive poisons taken in suicide attempts. Lavage is avoided if corrosive poisons have been taken. 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

Also called a stomach pump. For this procedure, a flexible tube is inserted through the nose, down the throat, and into the stomach and the contents of the stomach are suctioned out. The inside of the stomach is rinsed with a saline (salt water) solution.

bronchoalveolar lavage

gastric lavage
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. A gastric tube is passed and then the irrigating fluid is funneled into the tube. It is allowed to flow into the stomach by gravity. 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.
ice water lavage
administration of ice water through a stomach tube is used in the treatment of acute upper gastrointestinal hemorrhage. There is a risk of inducing hypothermia.
ruminal lavage
used in the treatment of carbohydrate engorgement. Serial gavages are performed until the fluid comes back clear. A 2.5 in (6 cm) diameter Kingman tube is necessary if any bulk of material is to be retrieved and a hose from a tap is the only practical irrigating mechanism.
subpalpebral lavage
a method of medicating the eye, particularly useful in treating corneal ulcerations in horses. Tubing is inserted from the conjunctival sac through the upper eyelid and extended onto the head or neck. Medication can then be delivered continuously in a drip.
