Paracetamol Toxicity in Septic Patients
Paracetamol Toxicity in Septic Patients
The investigators will examine the toxicity of therapeutic doses of paracetamol in patients
 in severe sepsis. Patients with fever and severe sepsis will be randomized to receive
 paracetamol or dypirone. The investigators will monitor blood glutathione and liver enzymes
 to look for potential toxicity.
Paracetamol is metabolized in liver using the glutathione system. This detoxification system
 is depressed during severe illness such as sepsis, trauma etc. The study will examine the
 toxicity of therapeutic doses of paracetamol in patients in severe sepsis. We believe that
 during sepsis, paracetamol metabolites are not fully detoxified and therefore are toxic to
 the patient.

 Patients with fever and severe sepsis will be randomized to receive paracetamol or dypirone.
 The investigators will monitor blood glutathione (as a surrogate marker for liver
 glutathione), liver enzymes and various clinical data (such as length of hospitalization) to
 look for a potential toxicity.
