Death from ferric chloride poisoning has never been reported in Taiwan. We report a fatality from the suicidal ingestion of ferric chloride solution used as an etching agent for printed circuitry. A 25-y-old woman presented with vomiting after ingestion of 200 ml ferric chloride solution (pH 1.0). She had hypoxemia and severe metabolic acidosis with respiratory alkalosis initially. Three hours after her ingestion she presented with drowsy consciousness, tachycardia, tachypnea and protracted vomiting. Laboratory studies showed leukocytosis, elevated glucose, aspartate aminotransferase, amylase, lactate dehydrogenase, and total bilirubin, coagulation defect and hemolysis. Aspiration pneumonia and vision loss were also noted. Four hours after ingestion cardiopulmonary arrest suddenly occurred after severe vomiting and she expired. Toxicological studies showed marked elevation of serum iron (2440 micrograms/dl); the estimated oral dose of ferric chloride was equivalent to 11.52 g (230 mg/kg) of elemental iron. This patient did not receive deferoxamine due to rapid deterioration and a late diagnosis. Deferoxamine should be given in any symptomatic patient or in the presence of anion gap metabolic acidosis with a history of ferric chloride ingestion.

The herbicide pendimethalin (STOMP) shares a similar chemical structure with nitro compounds such as dinitrobenzene, which was previously demonstrated to cause methemoglobinemia in mammals. However, reports on STOMP poisoning in humans are rare. We reviewed 71 STOMP poisoning cases (42 men and 29 women of mean age 43.9 +/- 2.5 y) reported to the Poison Control Center--Taiwan from September 1986 to September 1997 and summarized their clinical manifestations. Two incidences resulted from skin and eye contact. The rest were due to oral ingestion intentionally or accidentally. The average ingestion was 106.1 +/- 13.4 ml. Among them, 20 cases had no symptoms or signs, 38 had mild effects such as nausea, vomiting and sore throat, 7 had effects such as severe retching, hematemesis and seizures. Four patients expired due to also taking other herbicides (mainly organophosphates) and because of inadequate airway management. Adequate ventilation support was the major therapy in salvaging the poisoning cases.
