DIC is the simultaneous occurrence of widespread (micro) vascular thrombosis, leading to compromised blood supply to vital organs Although major bleeding can be seen in some, the more common complication of DIC is organ failure DIC is not a disease itself but secondary to an underlying disorder Sepsis, solid and hematologic malignancies, severe trauma, and obstetrical emergencies (amniotic fluid embolism, abruption) are the most common disorders associated with DIC A prospectively validated scoring system (Toh CH, et al. J Thromb Haemost 2007;5:604-6.) is used for diagnosis and is comprised of platelet count, fibrin split products, PT, and fibrinogen level The key to treating DIC is vigorous treatment of the underlying disorder Platelet transfusion is generally only given for patients with major bleeding (i.e. intracranial) with platelets counts < 50 k
