Overview

Disseminated intravascular coagulation, is a pathological process in the body where the blood starts to coagulate throughout the whole body. This depletes the body of its platelets and coagulation factors, and there is a paradoxically increased risk of hemorrhage.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Disseminated intravascular coagulation in itself is a life-threatening condition and must be treated as such irrespective of the causes.

Common Causes

• Abruptio placentae
• Amniotic fluid embolism
• Aortic aneurysm
• Drugs (e.g. Amphetamines)
• Eclampsia
• Giant hemangioma
• HELLP syndrome
• Hemolytic transfusion reaction
• Malignancy (especially APL)
• Sepsis
• Severe allergic reaction
• Transplant rejection
• Trauma (e.g. Fat embolism, head injury)
• Venomous snake

Do's

• The transfusion of platelets should be considered for those patients actively bleeding or at an increased risk of bleeding with a platelet count of less than 50,000 microliter.
• [[Fibrinogen level should be kept at a level greater than 100mg/dl
• Therapy with heparin used generally for patients with low grade DIC having predominantly thrombotic episodes such as acral ischemia and thrombophlebitis.

Dont's

• Do not base the transfusion of platelets or plasma primarily on laboratory results but generally should be for patients who are bleeding.
• Don't give recombinant human activated protein C to patients with increased risk of bleeding.
