Surgical management is limited to primary treatment of certain underlying disorders. Management of the DIC itself has the following basic features: Monitor vital signs Assess and document the extent of hemorrhage and thrombosis Correct hypovolemia Administer basic hemostatic procedures when indicated
Full Answer
What are the treatment options for thrombocytopenia?
In addition to rituximab and the thrombopoietin agents, combinations of different diagnostic and therapeutic modalities and various therapeutic approaches are the main strategies for difficult cases. A number of issues complicate the differential diagnosis and treatment of thrombocytopenia.
Does thrombin work in patients with DIC?
In order to work, thrombin must be able to be generated so might be expected to not work in massive heparin overdosage or in situations having no fibrinogen and/or platelets. Several small case series 17 –19 suggest possible efficacy in patients with DIC.
What is included in the evaluation of thrombocytopenia?
When evaluating a patient with thrombocytopenia, it is important to exclude pseudothrombocytopenia, a falsely low platelet count, caused by in vitroagglutination of platelets occurring in approximately 2% of patients with thrombocytopenia, when the blood is collected in ethylenediaminetetra-acetic acid (EDTA) containing tubes.
How is disseminated intravascular coagulation (DIC) treated?
The management of acute and chronic forms of disseminated intravascular coagulation (DIC) should primarily be directed at treatment of the underlying disorder.Often, the DIC component will resolve on its own once the underlying disorder is addressed.
What is the priority treatment for DIC?
Treatment of underlying conditions is recommended in three types of DIC, with the exception of massive bleeding. Blood transfusions are recommended in patients with the bleeding and massive bleeding types of DIC. Meanwhile, treatment with heparin is recommended in those with the non-symptomatic type of DIC.
What is used to treat DIC?
Management and Treatment Plasma transfusions to reduce bleeding. Plasma transfusion replace blood clotting factors affected by DIC. Transfusions of red blood cells and/or platelets. Anti-coagulant medication (blood thinners) to prevent blood clotting.
What does the nursing management of a patient with DIC include?
The following are the common nursing care planning and goals for clients with DIC: maintenance of hemodynamic status, maintenance of intact skin and oral mucosa, maintenance of fluid balance, maintenance of tissue perfusion, prevention of complications.
What do you administer in DIC?
The above four guidelines [3–6] recommended the administration of platelet concentrate (PC) and fresh frozen plasma (FFP) in DIC patients with active bleeding or those at high risk of bleeding requiring invasive procedures, without high-quality evidence.
Why Thrombocytopenia occurs in DIC?
DIC sometimes begins slowly and causes thromboembolic phenomena rather than bleeding. Severe, rapid-onset DIC causes severe thrombocytopenia, prolonged prothrombin time and partial thromboplastin time, a rapidly declining plasma fibrinogen level, and a high plasma D-dimer level.
Does DIC cause thrombocytopenia?
Severe, rapidly evolving DIC, in contrast, causes thrombocytopenia, depletion of plasma coagulation factors and fibrinogen, and bleeding. Bleeding into organs, along with microvascular thromboses, may cause dysfunction and failure in multiple organs.
How is DIC managed from a nursing standpoint?
Treatment of DIC To manage the bleeding, the physician may prescribe the replacement of clotting factors such as fibrinogen. Oxygen Therapy. Blood clots may prevent the oxygen to be delivered to the organs, especially the lungs and the heart. Therefore, oxygen therapy is required to support oxygenation in the body.
Why do you give anticoagulants for DIC?
Patients with DIC may benefit from prophylaxis to prevent venous thromboembolism, which will not be achieved with standard low-dose subcutaneous heparin. Theoretically, the most logical anticoagulant agent to use in DIC is directed against tissue factor activity.
What is a supportive treatment for a client with disseminated intravascular coagulation?
Supportive treatments may include: Plasma transfusions to replace blood clotting factors if a large amount of bleeding is occurring. Blood thinner medicine (heparin) to prevent blood clotting if a large amount of clotting is occurring.
How is DIC treated in sepsis?
The fundamental strategy for sepsis-associated DIC management is treatment of the underlying infection [81]. Unfractionated heparin and low-molecular-weight heparin are the most commonly used and readily available anticoagulants for a variety of thromboembolic diseases.
What is DIC treatment?
Treatment of DIC. Treatment of the underlying disease . The cornerstone of DIC treatment is providing treatment for the underlying disorders, such as the administration of antibiotics or surgical drainage in patients with infectious diseases and anticancer drugs or surgery in patients with malignant diseases.
What is the name of the DIC that is caused by a large amount of blood?
When both vectors for hypercoagulation and hyperfibrinolysis are remarkable and strong, major bleeding occurs, followed by death, if a sufficient amount of blood is not transfused; this type of DIC is called the massive bleeding or consumptive type of DIC.
What is DIC categorized into?
In conclusion, DIC is categorized into bleeding, organ failure, massive bleeding, and non-symptomatic types. The diagnosis and treatment of DIC should be carried out in accordance with the type of DIC based on the four guidelines on DIC. Acknowledgements.
What is reduced fibrinogen level?
A reduced fibrinogen level is a valuable indicator regarding a diagnosis of DIC due to leukemia or obstetric diseases; however, it is not observed in most septic DIC patients [3]. Elevated fibrin-related markers (FRMs), such as FDP [26], D-dimer [27], or soluble fibrin (SF), reflect fibrin formation.
What is the main symptom of DIC?
On the other hand, when the vector for hypercoagulation is remarkable and dominant, organ failure is the main symptom; this type of DIC is called the organ failure type, hypercoagulation predominance type or hypofibrinolysis type of DIC. This form of DIC is often observed in patients with infection, particularly sepsis.
Is heparin used for DIC?
Meanwhile, treatment with heparin is recommended in those with the non-symptomatic type of DIC. The administration of synthetic protease inhibitors and antifibrinolytic therapy is recommended in patients with the bleeding and massive bleeding types of DIC.
What is the first line of treatment for idiopathic ITP?
For primary idiopathic ITP, corticosteroids have been the standard first-line of treatment for symptomatic patients, with the addition of intravenous immune globulin (IVIG) or Rho(D) immune globulin (anti-RhD) for steroid-resistant cases.
What is ITP in medical terms?
Immune thrombocytopenic purpura (ITP) is an autoimmune condition that affects nearly 1:10,000 people in the world. It is traditionally defined by a platelet count of less than 100 x 109L, but treatment typically depends on symptomology rather than on the platelet count itself.
What is DIC in a patient?
Disseminated intravascular coagulation ( DIC) is the physiologic result of pathologic overstimulation of the coagulation system. Despite multiple triggers, a myriad of laboratory abnormalities, and a clinical presentation ranging from gross hemostatic failure to life-threatening thrombosis, or even both simultaneously, a simplified clinical approach augmented by a few readily available tests allows prompt identification of the process and elucidation of treatment opportunities. Platelet counts in DIC may be low, especially in acute sepsis-associated DIC, yet increased in malignancy-associated chronic DIC. Thrombotic risk is not a function of the platelet count, and thrombocytopenia does not protect the patient from thrombosis. The stratification of both thrombotic risk and hemorrhagic risk will be addressed.
What is the basic tenet of DIC?
A basic tenet involving one’s approach to DIC is that, if an underlying condition is responsible for triggering, promulgating, and continuing the pathologic free circulation of both plasmin and thrombin, one’s treatment is directed at reversing that cause.
What is a PF thrombosis?
The characteristic thrombosis that one might see in septic-generated DIC is purpura fulminans (PF). An example of an occult thrombosis is adrenal vein thrombosis with its inevitable subsequent adrenal hemorrhage, producing the so-called Waterhouse-Friderichsen syndrome.
What separates physiologic hemostasis from pathologic DIC?
What separates this physiologic hemostasis from pathologic DIC is whether the prothrombotic substances released by the product of magnitude and duration of the stimulus outstrips the clearance of these prothrombotic substances by the reticuloendothelial system, physiologic inhibitors of coagulation, and the fibrinolytic system.
Does DIC occur in isolation?
DIC does not occur in isolation, as it is essentially always the result of some underlying problem, which typically is rather obvious ( Table 1 ). When one reviews the clinical conditions that are associated with DIC, one sees a veritable litany of very ill patients in nearly every category of inhospital medical care.
Is platelet count low in DIC?
Platelet counts in DIC may be low, especially in acute sepsis-associated DIC, yet increased in malignancy-associated chronic DIC. Thrombotic risk is not a function of the platelet count, and thrombocytopenia does not protect the patient from thrombosis.
Is hemorrhage a DIC?
Therefore, hemorrhage is not as characteristic of cancer-initiated DIC as is thrombosis with overt manifestations as DVT and pulmonary embolism (PE) as well as thrombosis in the central nervous system CNS and the abdominal organs.
What is rTM used for?
Recombinant thrombomodulin. In Japan, rTM is widely used for treatment of DIC. Thrombomodulin binds with thrombin, and the resulting complex allows the conversion of protein C to APC. Additionally, thrombomodulin can also bind high-mobility group B (HBGM-1), which inhibits the inflammatory process.
Can tranexamic acid be used in DIC?
In general, antifibrinolytic agents (eg, tranexamic acid, ε-aminocaproic acid) should be avoided in DIC because they are known to produce thrombotic complications, such as myocardial infarction and renal artery thrombosis when there is systemic clotting.
Does heparin inhibit coagulation?
Experimental studies have suggested that heparin can at least partly inhibit the activation of coagulation in cases of sepsis and other causes of DIC. [ 78] . However, a beneficial effect of heparin on clinically important outcome events in patients with DIC has not yet been demonstrated in controlled clinical trials.
Is antithrombin gamma a recombinant form?
[ 88] A recombinant form of antithrombin, antithrombin gamma, is being developed as an alternative to antithrombin derived from human plasma.
Is heparin prescribed for DIC?
Heparin should be provided to those patients who demonstrate extensive fibrin deposition without evidence of substantial hemorrhage; it is usually reserved for cases of chronic DIC. Heparin is appropriate to treat the thrombosis that occurs with DIC.
Is platelet transfusion considered a thrombocytopenia?
Platelets. Platelet transfusion may be considered in patients with DIC and severe thrombocytopenia, in particular, in patients with bleeding or in patients at risk for bleeding (eg, in the early postoperative phase or if an invasive procedure is planned). The threshold for transfusing platelets varies.
Does DIC decrease antithrombin?
Moreover, antithrombin, the primary target of heparin activity, is markedly decreased in DIC, which means that the effectiveness of heparin therapy will be limited without concomitant replacement of antithrombin.
What is chronic DIC?
Chronic DIC refers to chronic activation of coagulation, often due to disseminated adenocarcinomas. This causes gradual consumption of coagulation factors, which can be compensated by the production of additional clotting factors.
Where do DIC clots form?
general concept of DIC. Normally, clots form locally at sites of vascular damage. These clots are subsequently degraded after tissue damage is repaired. The processes of clot formation and clot degradation (fibrinolysis) are localized and tightly regulated, based on a balance of counterregulatory proteins (procoagulants vs.
What is acute DIC?
Acute DIC results from an acute trigger of coagulation (e.g., sepsis or trauma). This leads to abrupt and exuberant depletion of coagulation factors, leading to hemostatic imbalances.#N#This chapter is predominantly about acute DIC – which is more immediately relevant to critical care medicine.
What causes a clot to form?
Clotting may be initiated by a variety of factors (e.g., bacterial lipopolysaccharides, tissue factor released by monocytes or the placenta, or damage to the endothelial glycocalyx). The fine balance of procoagulation vs. anticoagulation is broken, leading to widespread disseminated clot formation.
Does cirrhosis cause thrombocytopenia?
Cirrhosis commonly causes thrombocytopenia and reductions in clotting factor levels (e.g., elevation of INR). Rarely, patients with cirrhosis may fail to clear endogenous tPA, leading to ongoing fibrinolysis (accelerated intravascular coagulation and fibrinolysis AICF) – a condition which can closely mimic DIC.
Is thromboelastography better than INR?
Thromboelastography is likely a better tool to determine the true balance of coagulation.
Do patients with TTP have normal coagulation factors?
Patients with TTP, HUS, or drug-induced thrombotic microangiopathy should have normal coagulation factors (e.g., INR, PTT, fibrinogen), because clots are composed of platelets and don't involve activation of the coagulation system.
