Analyze the causes of anemia when DIC occurs

1.Hyperfibrinolysis, causing coagulation dysfunction and bleeding in multiple parts of the body, such as **, mucous membranes, etc.;

2.Microvascular hemolysis, fibrin destroys red blood cells, and may present as progressive anemia.

Answer]: C Patients with disseminated blood endoductal coagulation (DIC) may be accompanied by a special type of chronic anemia, namely microangiopathic hemolytic anemia, which is mainly caused by the fragmentation of red blood cells by the deposition of a pure cryptin network in the microvessels.

a.Regenerative and segment disorder anemia.

b.Hemorrhagic anemia.

c.Toxic anemia is called for praise.

d.Hemolytic anemia.

e.Iron deficiency anemia.

Correct answer No suspect : D

The main direct cause of bleeding caused by DIC is ().

a.Consumption of coagulating substances.

b.Vascular endothelial cells are impaired.

c.Secondary fibrin slag lysis hypervolatization.

d.Vitamin K deficiency.

Build increases. Correct answer: ace

The main cause of bleeding in patients with DIC is ().

a .Disorders in the synthesis of coagulation factors in the liver.

b .The clotting substance is consumed in large quantities.

c .Clotting factors are activated.

d .Antithrombin substances increase.

e .Increased vascular permeability.

Refer to parsing. During the occurrence and development of DIC, a large amount of various coagulation factors and platelets are consumed, and the blood enters a state of hypocoagulation, which is easy to cause bleeding.

Correct answer: c

Analysis: The fibrin strips and mesh formed by the coagulation of the blood vessels in the blood vessels cause mechanical damage to the red blood cells when they pass through, and the fragility of the red blood cells increases due to ischemia, hypoxia, toxins and fibrin attachment on the surface, resulting in the deformation and rupture of red blood cells and hemolysis, resulting in anemia.

That's right. The clinical manifestations of DIC are related to the underlying disease. Who is in the ascendancy during DIC will largely determine the characteristics of the clinical presentation.

Patients with predominantly coagulation may present only with thromboembolic lead silent DIC; Fibrinolysis predominantly can develop acute wasting hemorrhage. A broad spectrum of clinical manifestations involving different types of DIC can also be presented in between.

1.Haemorrhage. Multisite hemorrhage often predicts acute DIC. **Purpura, ecchymosis, and bleeding from the puncture site or injection site are more common. Bleeding persistently and blood does not clot at the wound site during or after surgery.

Heavy bleeding can cause hemorrhagic anemia.

2.Thromboembolism.

Microthrombosis in various organs is caused by thrombosis in arterioles, capillaries, or venules, resulting in hypoperfusion, ischemia, or necrosis of the organ. Manifestations** terminal hemorrhagic dead spots; Gangrene of the fingers or toes.

When fast-moving red blood cells encounter these tiny blood clots, they are easily destroyed by mechanical force, resulting in hemolysis.

Answer]: When intravascular coagulation (DIC) occurs, the fibrous egg trapped in the microvascular body rushes through the white net to cut the red blood cells into fragments and collapse, causing anemia, which is called microangiopathic hemolytic anemia.

Answer]: C search state analysis: Anemia caused by the fragmentation of red blood cells by fibrin deposition in the microvascular network during DIC is called "microangiopathic hemolytic anemia". Master the knowledge points of "disseminated intravascular Zen mask coagulation".
