Gastric lavage
From Biocrawler, the free encyclopedia.
Gastric lavage is the process of cleaning out the contents of the stomach. Typically, a nasogastric tube is placed through the nose and threaded to the stomach; water is then introduced into the stomach and sucked out again, bringing along stomach contents. Nasogastric lavage is most commonly used when gastric bleeding is present, both to diagnose the hemorrhage and remove the blood. Toxic substances can also be removed with this method ("stomach pumping"), but activated charcoal is more commonly used to neutralize toxic ingestions.
