Nasogastric Aspiration and Lavage Definition

Nasogastric Aspiration and Lavage – the clinical term for the procedure commonly called “pumping the stomach.” In nasogastric aspiration and lavage, the health-care provider inserts a narrow tube (catheter) through the nose, down the back of the throat and the esophagus, and into the stomach.

The stomach’s contents are then sucked through the tube. The health-care provider may also use the tube to instill a rinsing solution, often a mixture of liquid and activated charcoal, into the stomach to absorb and neutralize remaining gastric content. Nasogastric aspiration and lavage is most commonly an emergency treatment for ingested toxins, including drug overdose, though also can help diagnose gastric bleeding.
