The duration of bleeding Duque - an important study, which allows to identify the rate of discontinuation of blood from the capillaries. This survey allows you to find out the condition of the blood vessels and whether they are able to quickly shrink when traumatic injury.
How to conduct research
Such an examination is appointed, if the doctor suspects that the patient has a problem with a reaction to blood clotting, or he will have surgery. In addition, this survey refer women before delivery. There is the following algorithm such analysis:
- To conduct the study, the doctor prepares a thin needle.
- After preparing the doctor punctures the subcutaneous layer. The depth of the puncture must be a maximum of 2 mm. It can be performed in any parts of the body. To check the duration of the allocation of blood pierce the finger or earlobe.
- In the next step can not do without filter paper. It is necessary to apply it to the puncture site every 35 seconds (until the sheet of paper remain traces of flowing blood).
Skin puncture is rarely done. This procedure is carried out in small clinics that lack equipped with the modern requirements of the laboratory.
On the investigation of a bleeding Duque should prepare: do not eat for 8 hours before examination. 2 days prior to the analysis, it is desirable to give up alcohol.
It is also necessary to refuse from excessive exercise. Before you go to the treatment room, you need to calm down. To feel safer, you can sit for 10 minutes.
If the patient uses drugs that affect blood clotting, it should inform the doctor. Then the doctor will be able to make the necessary adjustments in time to analyze the results of Duke.
Norm and deviation
The normal bleeding time for Duque should be 4 minutes. If the duration of bleeding is less or more, it indicates that there is a violation.
When after the procedure is greater than the length of the blood separation means, in patients with hereditary thrombocytopenia or a deficiency of vitamin C. You may receive a similar symptom in the case of aspirin use.
With regard to reducing the duration of release of blood, such a symptom appears if the patient has impaired renal or thrombocytopathy work. Furthermore, in case such symptom of acute leukemia.
Reduced the duration of blood separation and in the case of a patient's disease associated with impaired workability thrombi. For example, the cause of this symptom may be a thrombosis.
Furthermore, during such examination doctors produce count of erythrocytes and thrombocytes, as well as their adhesion. Red cells and platelets are arranged on the damaged vessel walls.
We should say what parameters affect blood clotting. It depends on protrombiirovannogo period, the duration of bleeding and clotting. Also, this process affects fibrinogen and antithrombin.
What if rising or falling values
In the event of a fault, indicators, doctors prescribe medications to help normalize blood circulation. If the patient has an increased clotting, it is assigned NSAIDs. In the case of reduced clotting, doctors recommend a patient use anticoagulants.
To improve the health status of patients were administered vitamin complexes. For recovery you want to restore metabolic processes. In the case of severe bleeding patient is prescribed a blood transfusion. Pregnant women is directed to the analysis of the hormone LH.
If the cause of this problem - vitamin C deficiency, responsible for the human immune system, the patient is prescribed analysis igg antibodies. Such an analysis makes it possible to evaluate the ability of immune responses to antigens.
In addition, if you have problems with blood clotting patient is advised to be tested for serotonin. This hormone affects blood clotting. Since poor blood clotting can be a cause of cancer, the patient is further directed to pass serum for analysis.
