Septic Disseminated Intravascular Coagulation (DIC) is a complex, life-threatening condition that occurs when severe sepsis or septic shock triggers abnormal blood clotting throughout the body.
Here's a breakdown:
-
Sepsis and Septic Shock: These are severe illnesses caused by the body's overwhelming response to an infection. This response can lead to widespread inflammation and organ damage.
-
Disseminated Intravascular Coagulation (DIC): This is not a disease in itself, but a complication of other conditions like sepsis. In DIC, the normal process of blood clotting goes awry.
-
Initial Phase - Excessive Clotting: The infection-induced inflammation activates the coagulation cascade, leading to the formation of numerous small blood clots throughout the blood vessels. These clots can obstruct blood flow to vital organs, resulting in organ damage and failure.
-
Later Phase - Bleeding: As the body's clotting factors and platelets are consumed in forming these widespread clots, the body loses its ability to clot normally. This can then lead to uncontrolled bleeding, both internally and externally.
-
-
Septic DIC: Therefore, septic DIC is DIC that is specifically caused by sepsis or septic shock. The initial infection triggers the chain of events leading to the simultaneous clotting and bleeding abnormalities.
In summary, Septic DIC involves a dangerous combination of:
- Widespread blood clotting due to sepsis.
- Depletion of clotting factors leading to increased risk of bleeding.
- Potential for organ damage due to blocked blood flow.
Because of the contradictory clotting and bleeding problems, septic DIC is incredibly difficult to manage and requires aggressive medical intervention, including treating the underlying sepsis, managing blood clotting abnormalities, and providing supportive care for organ dysfunction.
