Disseminated intravascular coagulation (DIC) is a rare, life-threatening condition that prevents blood from clotting normally. The blood clots reduce blood flow and can block blood from reaching bodily organs. This increased clotting can use up the blood’s platelets and clotting factors. Fewer platelets and clotting factors available result in excessive bleeding.
DIC is a serious condition that can lead to death. If you have bleeding that won’t stop, go to the emergency room, or call 911.
When the proteins used in your normal clotting process become overly active, it can cause DIC. Infection, severe trauma (i.e., brain injuries, crushing injuries) inflammation, surgery, and cancer are all known to contribute to this condition.
Some less common causes of DIC include the following:
You may also develop DIC if you go into shock.
Your risk for DIC is elevated if you have recently:
Bleeding, sometimes from multiple locations on the body, is one of the more common symptoms of DIC. Bleeding from the mucosa tissue (in the mouth and nose), and bleeding from other external areas may occur. In addition, DIC may also cause internal bleeding.
Other symptoms are:
If you have cancer, DIC generally begins slowly, and clotting in the veins is more common than excessive bleeding.
DIC can cause complications, especially when it is not treated properly. The clots in the vessels will result in an inadequate oxygen supply reaching your organs. This has the potential to cause organ damage. Other complications include:
DIC may be identified through various tests related to your levels of platelets, clotting factors and other blood components. However, there is not a standard procedure. The following are some tests that may be conducted if your doctor suspects DIC.
DIC treatment depends on what is causing the disorder. Treatment of the underlying condition is the main goal. To treat the clotting problem, you may be given an anticoagulant called heparin to reduce and prevent clotting. However, heparin may not be administered if you have a severe lack of platelets or are bleeding too excessively.
People with acute DIC require hospitalization, often in an intensive care unit (ICU), where treatment will attempt to correct the problem causing the DIC while maintaining the function of the organs.
A transfusion may be needed to replace the platelets that you are missing. Plasma transfusions have the ability to replace the clotting factors that you are lacking.
Your prognosis relates to what is causing DIC. If the initial problem can be corrected, then DIC will resolve. If not, DIC can be life threatening.
