Decontamination is a critical step in the management of poisoning, aiming to limit further absorption of the toxic substance. Methods of decontamination include gastric lavage, induced emesis, and skin decontamination. Gastric lavage involves the insertion of a tube into the stomach to wash out its contents and is typically used in severe cases. Induced emesis, using agents such as ipecac syrup, is less commonly recommended due to the risk of complications.
