  2. 2. CONTAIN… • • • • • • • • • • Definition Pathophysiology Classification Etiology Tests Clinical manifestation of DIC Complication Treatment Nursing Process Reference
  3. 3. DEFINITION • DIC is an acquired syndrome characterized by the intravascular activation of coagulation with loss of localization arising from different causes. It can originate from and cause damage to the microvasculature, which if sufficiently severe, can produce organ dysfunction
  4. 4. Coagulation Exposure of blood to procoagulant substances Anticoagulation Balance Clotting factors & Platelet depletion Secondary fibrinolysis (FDP formation) Coagulation Fibrinolysis Coagulation Fibrinolysis widespread thrombosis systemic hemorrhagic syndrome Disseminated Intravascular Coagulation
  5. 5. SYSTEMIC ACTIVATION OF COAGULATION Intravasc ular depositio n of fibrin Thrombosis of small and midsize vessels Organ failure Depletion of platelets and coagulation factors Bleeding DEATH
  6. 6. Pathophysiology
  7. 7. . Classification • Acute DIC :It happened rapidly, the coagulopathy is dominant and major symptoms are bleeding and shock, mainly seen in severe infection, amniotic fluid embolism. • Chronic DIC: it happened slowly and last several weeks, thrombosis and clotting may predominate mainly seen in cancer.
  8. 8. Etiology • DIC is not a primary disease, but a disorder secondary to numerous triggering events such as serious illnesses. • infectious disease 31%~43% • (bacterial, viral, parasitic diseases and so on) Bacterial infection, in particular septicemia, is commonly associated with DIC. •
  9. 9. Continuo cancer 24%~34% (Acute promyelocytic leukemia, acute myelomonocytic or monocytic leukemia, disseminated prostatic carcinoma Lung, breast, gastrointestinal malignancy) Obstetric complications 4%~12% amniotic fluid embolus, septic abortion, and so on) (
  10. 10. Continuo • severe tissue injury 1%~5% (burn, heart shock, fracture and so on) Head trauma in particular is strongly associated with DIC; both local and systemic activation of coagulation may be detected after such an event. systemic disease (malignant hypertension , Acute respiratory distress syndrome<ARDS>, hemolytic transfusion reaction)

  13. 13. Symptoms and Signs COMPLICATION Bleeding Thrombosis Hypotension or shock Organ dysfunction
  14. 14. Continuo • Bleeding : It may occur at any site, but spontaneous bleeding and oozing at venipuncture sites or wounds are important clues to the diagnosis. • Thrombosis: It is most commonly manifested by digital ischemia and gangrene, renal cortical necrosis and hemorrhagic adrenal infarction may occur.
  15. 15. Treatment Modalities TREATMENT • Treat the underlying cause • Provide supportive management of complications • Stop abnormal coagulation and control bleeding by replacement of depleted blood and clotting components(FFP, Platelets,PRBC) • Medications can be used and choice depends on the patient’s condition (Heparin, Antithrombin III (ATIII), ( Fibrinolytic inhibitors)
  16. 16. Nursing Process--Planning the Care of the Patient With DIC • Major goals include maintenance of hemodynamic status, maintenance of intact skin and oral mucosa, maintenance of fluid balance, maintenance of tissue perfusion, enhanced coping, and absence of complications 19
  17. 17. Interventions • Assessment and interventions should target potential /actual sites of organ damage • Monitor and assess carefully for bleeding and thrombosis • Avoid trauma and procedures that increase the risk of bleeding, including activities that increase intracranial pressure
