Failure of dialysis therapy in potassium dichromate poisoning.
A fatal case of oral ingestion of potassium dichromate is presented. Following an initial presentation of abdominal pain and vomiting, the patient had a rapid progression to coma with the development of methemoglobinemia, coagulopathy, gastrointestinal hemorrhage, and respiratory distress syndrome. A blood concentration of chromium on admission was 5,800 mcg/dL, 80% of which was found to be in the intracellular fraction. Supportive treatment was also initiated as a four-hour period of hemodialysis followed by a one-hour period of charcoal hemoperfusion. Neither of these treatment modalities was found to significantly remove chromium from whole blood and neither seemed to affect the progression or outcome of this intoxication. We conclude that the ingestion of potassium dichromate is highly toxic and may rapidly lead to death. Hemodialysis and charcoal hemoperfusion appear to have little role in the management of chromium intoxication.
