Coagulopathies in Critical Illness - DIC

  • Disseminated intravascular coagulation (DIC) is an acquired syndrome of intravascular coagulation and is commonly encountered in critically ill patients.
  • Think about DIC in the critically ill patient with oozing at vascular sites (or wounds) and the following lab abnormalities:
    • Thrombocytopenia
    • Prolonged PT and aPTT
    • Decreased fibrinogen
    • Elevated fibrin split products and D-dimer
  • Guidelines for the management of DIC are primarily based on expert opinion and include:
    • Treat the underlying condition (i.e., sepsis)
    • Transfuse platelets if < 50,000 per mm3
    • Transfuse FFP to maintain PT and aPTT < 1.5 times normal control
    • Transfuse cryoprecipitate to maintain fibrinogen levels > 1.5 g/L
  • The use of heparin remains controversial and cannot be routinely recommended.
