A new patient has been brought to the intensive care from the C-section suite. The baby is healthy with normal APGAR scores. During closing, the surgeon noted a hemorrhage occurring in the abdomen. After the prolonged procedure to repair the artery was concluded, the patient had received 15 units of packed red blood cells, 10 units of fresh frozen plasma, and 5 units of platelets. The patient is in the ICU at risk for disseminated intravascular coagulopathy (DIC).


Disseminated Intravascular Coagulopathy (DIC) is a complex disorder characterized by abnormal blood clotting throughout the body, leading to both bleeding and thrombosis. It is typically triggered by an underlying condition or event that activates the coagulation system to an excessive degree. In this case, the patient had a hemorrhage during the C-section procedure, which puts her at risk for developing DIC. This assignment will critically analyze the pathophysiology, clinical manifestations, diagnostic criteria, and management strategies for DIC in a postpartum patient.

Pathophysiology of DIC

DIC is a condition in which the balance between clotting and bleeding is disrupted, favoring the formation of blood clots within the vasculature while also causing bleeding in other sites. The underlying mechanism involves the release of tissue factor, activated platelets, and other procoagulant substances, leading to widespread activation of the coagulation cascade. This excessive activation of clotting factors results in the formation of microthrombi throughout the body, leading to tissue ischemia and organ dysfunction.

The initial trigger for DIC in this patient was the hemorrhage during the C-section procedure. Tissue factor, released from injured tissues, activates the extrinsic pathway of the coagulation system. This leads to the formation of fibrin clots, primarily localized at the site of vascular injury. However, in DIC, unrestricted activation of the coagulation cascade occurs, leading to widespread clot formation in small blood vessels and capillaries. The consumption of clotting factors and platelets, along with the release of clotting inhibitors, eventually leads to a state of relative anticoagulation.

Clinical Manifestations of DIC

The signs and symptoms of DIC are variable and depend on the extent of clot formation and bleeding. In the initial stages, the patient may present with generalized bleeding manifestations, such as petechiae, ecchymosis, and oozing at venipuncture sites. As the condition progresses, more severe bleeding can occur, including gastrointestinal bleeding, hematuria, and intracranial hemorrhage.

At the same time, the formation of microthrombi in small blood vessels can lead to ischemia in various organs. This can manifest as organ-specific symptoms, such as renal dysfunction, respiratory distress, mental status changes, and cardiac abnormalities. Additionally, patients with DIC may experience multi-organ failure as a result of widespread tissue damage and organ dysfunction.

Diagnosis of DIC

DIC is a challenging condition to diagnose due to the heterogeneity of its presentation and the presence of multiple underlying conditions that can mimic or coexist with DIC. Therefore, a systematic approach incorporating clinical, laboratory, and imaging findings is crucial for an accurate diagnosis.

The International Society on Thrombosis and Haemostasis (ISTH) has provided diagnostic criteria for DIC, which include the scoring system based on laboratory parameters. These parameters include platelet count, prothrombin time, fibrin degradation products, and fibrinogen level. In this patient, laboratory testing should be done to assess these parameters and determine the severity of DIC. Additionally, imaging studies, such as computed tomography (CT), can be helpful in assessing the extent of clot formation and identifying any underlying conditions contributing to DIC.

Management of DIC

The management of DIC involves addressing both the underlying cause and the coagulation abnormalities. In this patient, the primary intervention should be to control the ongoing bleeding and stabilize the patient’s condition. This can be achieved through measures such as surgical intervention, blood product transfusion, and administration of clotting factor concentrates. The specific management plan will depend on the severity of DIC, the extent of bleeding, and the underlying condition.

The primary goal in managing DIC is to restore the balance between coagulation and fibrinolysis, and thus stabilize the patient’s condition. This can be achieved through the administration of blood products, such as packed red blood cells, fresh frozen plasma, and platelets, to replace depleted clotting factors and correct any underlying coagulation abnormalities. Additionally, fibrinolytic inhibitors, such as aminocaproic acid, can be used to prevent the breakdown of clots and promote clot stability.


DIC is a complex disorder characterized by abnormal blood clotting and bleeding throughout the body. This patient, who developed DIC following a hemorrhage during a C-section procedure, requires prompt diagnosis and management to prevent further complications. Understanding the pathophysiology, recognizing the clinical manifestations, and employing appropriate diagnostic tests and management strategies are crucial for optimizing outcomes in patients with DIC.
