title: Pyridoxine therapy in a patient with severe hydrazine sulfate toxicity.
abstract: OBJECTIVE
  To report hydrazine sulfate as a cause of severe encephalopathy and to report its response to high-dose pyridoxine therapy.
  
  
  METHODS
  Case report.
  
  
  METHODS
  An adult six-bed medical/surgical intensive care unit of a general hospital.
  
  
  METHODS
  One patient who developed severe encephalopathy after hydrazine sulfate.
  
  
  METHODS
  5 g i.v. pyridoxine.
  
  
  RESULTS
  After 180 mg/day for 2 wks followed by 360 mg/day of hydrazine sulfate ingestion, our patient suffered severe encephalopathy. He received mechanical ventilation with attendant supportive measures and high-dose pyridoxine. The patient's encephalopathy resolved 24 hrs after receiving pyridoxine.
  
  
  CONCLUSIONS
  Severe encephalopathy could result from hydrazine sulfate toxicity. High-dose pyridoxine is an effective treatment to reverse this encephalopathy.
