be washed copiously. Gastrointestinal decontamination

is the process of preventing or reducing absorption of a

substance after it has been ingested. The primary

strategies for GI decontamination are gastric emptying,

adsorption of poison, and catharsis. Minimal indications

for considering GI decontamination include: 1) the

poison must be potentially dangerous; 2) the poison

must still be unabsorbed in the stomach or intestine, so

it must be soon after ingestion; and 3) the procedure

must be able to be performed safely and with proper

technique. Gastric emptying is rarely recommended

anymore, but the administration of activated charcoal

and the performance of whole bowel irrigation remain

therapeutic options.
