... COPPER SULFIDES ... ARE POORLY ABSORBED. /COPPER SULFIDES/|Ionic copper is absorbed from the stomach, duodenum, & jejunum. The initial absorption is about 30%, but the effective net absorption is only about 5% due to excretion of copper into the bile; biliary copper is bound to protein, & this complex is not reabsorbed. Absorption is influenced by a number of factors including the chemical forms of copper: oxides, hydroxides, iodides, glutamates, citrates, & pyrophosphates of copper are readily absorbed, but copper sulfides & other water insoluble salts are poorly absorbed. Copper complexes of some amino acids are easily absorbed, whereas copper porphyrins present in meat are very poorly absorbed. /Soluble copper salts/

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . /Copper and related compounds/|Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Start an IV with lactated Ringer's /SRP: "To keep open", minimal flow rate/. Watch for signs of fluid overload. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Use proparacaine, hydrochloride to assist eye irrigation ... . /Copper and related compounds/
