Effect of gut lavage on phenobarbital elimination in rats.

In the management of intoxications, the major goals are enhanced elimination of the toxin from the organism and prevention of further absorption. Absorption of an orally administered substance from the gastrointestinal tract can be decreased by adequate washing of the stomach. Delayed absorption of the substance from the small intestine cannot be avoided by this procedure and after the gastric lavage, a nonspecific absorbent must be administered and diarrhea induced (1). This study demonstrates that iatrogenic diarrhea via gut lavage can also eliminate toxins already absorbed by the body.
