In which of the poisoning, gastric wash is contraindicated?
Gastric lavage is useful any time within 3 hours after ingestion of a poison. The only absolute contraindication of gastric lavage is corrosive poisoning (except carbolic acid), owing to the danger of perforation. Precautions should be taken for convulsant poisons, in comatose patients, volatile poisons, upper alimentary diseases, marked hypothermia, and hemorrhagic diathesis.
