[Diagnosis and management of obstetric acute disseminated intravascular coagulation]. 
Twenty-seven in-patients with obstetric DIC in our hospital from Jan. 1971 to Dec. 1990 were analysed retrospectively.  The incidence was 0.12% in the first decade and 0.02%, in the second, showing a difference of significance between them.  The most common predisposing factors included amniotic fluid embolism, abruptio placenta and hemorrhagic shock.  Bleeding from multi-organs in various extent and coagulation disorders occurred in all those 27 cases. [ Besides anti-shock treatment, heparin was employed together with fibrinogen in 4 postpartum and 1 antepartum DIC patients, fibrinogen alone in 8 cases, and hysterectomy in 11 cases.  17 patients were saved and 9 died.  It is important that early diagnosis and much attention paid to clinical characteristics together with serial laboratory tests.  Key management should include prompt treatment and eradication of predisposing factors.  Quick decision spite of to terminate the pregnancy and even hysterectomy should be done in some risks.
