Treatment of severe thallium intoxication.

We report a successfully treated case of severe thallium intoxication. In spite of very high serum thallium (5,240 micrograms/L), symptomatology was minor and recovery complete. Prussian Blue was administered, diuresis was enhanced by intravenous fluids and a prolonged hemodialysis was started early. High blood flows (300 mL/min) and intravenous potassium chloride supplements, to mobilize thallium from the tissues, resulted in good clearances (96 to 150 mL/min). In order to prevent the well known complications, we recommend aggressive treatment of severe thallium intoxication.
