What is the management of Disseminated Intravascular Coagulation (DIC)?

From the Guidelines

The management of Disseminated Intravascular Coagulation (DIC) should focus on treating the underlying cause and providing supportive care with blood component therapy, such as platelets, fresh frozen plasma, and cryoprecipitate, as recommended by the most recent guidelines 1. The primary goal is to address the underlying condition, such as sepsis, trauma, or malignancy, while also correcting coagulopathy.

• Supportive measures include:
  • Platelet transfusion to maintain the platelet count above 50 × 10^9/L in patients with active bleeding or at high risk of bleeding 1
  • Fresh frozen plasma (15–30 mL/kg) with careful clinical monitoring to decide on dose adjustments, or prothrombin complex concentrates in cases of concerns over volume overload 1
  • Cryoprecipitate or fibrinogen concentrate in actively bleeding cases with persistently low fibrinogen values (below 1.5 g/L) despite supportive measures 1
• Anticoagulation with unfractionated heparin or low-molecular-weight heparin may be considered in patients with predominant thrombotic manifestations or when fibrinogen levels continue to fall despite replacement therapy, though this remains controversial 1
• Continuous monitoring of coagulation parameters, including platelet count, PT, PTT, fibrinogen, and D-dimer, is essential to guide therapy and assess response 1
• The use of antifibrinolytic agents, such as tranexamic acid, is not recommended for routine use in hyperfibrinolytic DIC, but may be considered in cases of therapy-resistant bleeding 1
• The role of recombinant FVIIa in the management of cancer-related DIC remains uncertain and is not recommended due to associated thrombotic risks 1

From the FDA Drug Label

Heparin Sodium Injection is indicated for: ... Treatment of acute and chronic consumptive coagulopathies (disseminated intravascular coagulation); The management of Disseminated Intravascular Coagulation (DIC) may include the use of heparin as an anticoagulant therapy, as it is indicated for the treatment of acute and chronic consumptive coagulopathies, including DIC 2.

• Key points:
  • Heparin may be used in the treatment of DIC
  • The use of heparin in DIC is based on its anticoagulant properties The use of heparin in DIC should be done under the guidance of a healthcare professional, as it requires careful monitoring and management to avoid potential complications.

From the Research

Overview of Disseminated Intravascular Coagulation (DIC) Management

The management of DIC is a complex process that involves treating the underlying condition, as well as providing supportive care to manage the coagulopathy. The following are key points to consider:

• The cornerstone of DIC management is the treatment of the underlying triggering disease 3, 4, 5, 6.
• The use of diagnostic scores such as ISTH, JMHW, or JAAM is recommended over standalone tests for suspected DIC 3.
• Transfusion of platelets or plasma should not be based solely on laboratory results, but rather reserved for patients with bleeding or at high risk of bleeding 3, 4.

Treatment of Underlying Condition

The treatment of the underlying condition is crucial in managing DIC. This may involve:

• Antibiotics for sepsis
• Chemotherapy for malignancy
• Supportive care for trauma or obstetric complications
• The use of heparin may be considered in certain cases, such as thrombosis or severe sepsis 4, 5, 6.

Supportive Care

Supportive care is essential in managing DIC, and may include:

• Transfusion of platelets, plasma, or coagulation factor concentrates for patients with major bleeding or at risk of hemorrhagic complications 4, 6.
• Administration of fresh frozen plasma (FFP) or cryoprecipitate for patients with severe hypofibrinogenemia 4.
• Use of antithrombin or other anticoagulants may be considered in certain cases, but the evidence is limited 3, 4.

Specific Considerations

Certain patient populations may require special consideration, such as:

• Patients with severe sepsis or septic shock, who may benefit from the use of recombinant human activated protein C 3, 4.
• Patients at high risk of bleeding, who may require prophylactic platelet transfusion or other supportive care 4.
• Patients with chronic DIC, who may require long-term anticoagulation therapy 5.
