What is the management approach for DIC?

• A. Treat underlying cause, administer clotting factors, and provide supportive care.
• B. Immediate anticoagulation and no support.
• C. Isolate patient and avoid any transfusions.
• D. Increase platelet production with growth factors only.

Answer: (A)

Disseminated intravascular coagulation presents as a consumptive coagulopathy where widespread activation of clotting leads to both microthrombi and rapid depletion of platelets and coagulation factors, causing bleeding as the process exhausts the body's resources. The treatment plan focuses on stopping the trigger and replacing what's been used up, with supportive care to keep the patient stable.

First, address the underlying cause, such as severe infection, obstetric emergencies, trauma, or malignancy. Halting the driver of coagulation prevents further consumption and progression of DIC. At the same time, replace depleted components to control bleeding: fresh frozen plasma provides the missing coagulation factors; platelets are transfused if there is significant thrombocytopenia with bleeding or if counts are dangerously low; cryoprecipitate may be used when fibrinogen is low. Supportive measures include maintaining hemodynamics, ensuring adequate organ perfusion, and closely monitoring coagulation studies and transfusion needs.

Anticoagulation is not the default approach when bleeding is prominent, because the priority is to control consumption and bleeding by treating the trigger and replenishing factors; anticoagulation may be considered only in specific scenarios with predominant thrombosis, but not as the primary strategy.
