The glycols, including ethylene and propylene glycol, are found in many antifreezes, solvents, detergents, and lacquers, and their ingestion is a common cause of accidental poisoning in the U.S. The intoxicated patient should be treated by decontaminating the stomach in order to decrease uptake of the chemical. Sodium bicarbonate is also given if metabolic acidosis develops. Seizures, brain damage, ophthalmic injury, and renal failure are common complications of exposure. Support of the patient often includes parenteral administration of thiamine and other vitamins, as well as of alcohol dehydrogenase inhibitors.
