* Top three etiologies: infection, malignancy, and trauma/surgery, each account for 10-20% of cases.
* '''Bacterial sepsis''' (83%), '''Trauma''' (31%), '''Cancer''' (e.g. APML, 6.8%), placental abruption, preeclampsia, amniotic fluid embolism, burn, hyperthermia, rhabdomyolysis, infection, transfusion reaction (ABO incompatibility), snake venom, aortic aneurysm

Compared with the non-DIC group, the DIC group had prolonged K time, decreased α angle, increased R value, and decreased CI and MA value (P<0.05). With increase of SOFA scores, R value and K value increased significantly, and α angle, MA value, and CI decreased significantly (P<0.05). According to TEG, platelet function and fibrinogen function of DIC patients were significantly reduced, and the body showed hypocoagulability. (PMID: 30988714)
