RESUMEN
Bluish vomiting is a symptom of poisoning that is rarely seen in Western emergency departments. Consequently, physicians are not aware of the diagnosis, complications, and treatment of this unusual form of intoxication. In this article, we report a case of bluish vomiting that occurred after an accidental ingestion of copper sulphate. In the discussion, we review three life-threatening causes of bluish vomiting (copper sulphate, boric acid, and paraquat ingestion), and we discuss their respective clinical manifestations, specificities, complications, and management therapies.

Although a plethora of reports on life-threatening complications of salt emesis has been published since the early 1960s, salt is still used to induce emesis in cases of intoxication in the clinical as well as in the domestic setting. We report three cases of fatal hypernatremia after salt was used as an emetic. All fatalities were subjected to medico-legal autopsy at the Institute of Legal Medicine in Hamburg, Germany. In all cases, symptoms of cerebral damage such as seizures, fever and somnolence developed within hours after salt ingestion. All individuals were admitted to hospital before their deaths. Here, severe hypernatremia (up to 245 mmol/l) was detected, and all patients died under the clinical picture of cerebral edema despite intensive medical treatment. At autopsy, unspecific signs of a central regulatory failure were present. Histology revealed crenated red blood cells and few venous microthrombi in internal organs. Neuropathological investigations yielded no specific results but confirmed fatal cerebral edema and excluded other cerebral causes of death. Viewing the results of clinical and post-mortem investigations together, death could clearly be attributed to excessive salt intake in all cases.

An adolescent boy returned home from a party and told his parents he may have taken some pills while there. He was given saltwater to drink, in an effort to induce emesis. He vomited numerous times, then seized. Hypernatremia (195 mmol/L) was diagnosed at the community hospital, and he was transferred to a pediatric intensive care facility. He suffered numerous complications and died from cerebral herniation. This case is presented to remind physicians of the dangers of this obsolete therapy.

CASE HISTORY: A 25-year-old woman who had ingested about 20 tablets of diazepam 2.5 mg in a suicide attempt was given cupric sulfate 2.5 g in 1750 mL water as an emetic, but died 3 days later. On autopsy, death was attributed to acute hemolysis and acute renal failure due to copper poisoning. Copper concentrations were 5.31 microg/mL in whole blood, 19.0 microg/g in the liver, 8.9 microg/g in the kidney, 1.1 microg/L in the brain, 1.1 microg/g in the gastric wall, 1.5 microg/g in the jejunal wall, 0.3 microg/g in the colon wall, 4.6 microg/g in the gastric contents, and 12.6 microg/g in the intestinal contents (fresh weight). This case and 10 others from the Chinese medical literature provide additional evidence that cupric sulfate is a corrosive poison and contraindicated as an emetic.
