The purpose of blood coagulation is to know whether the patient's hemostatic function is defective before operation.
In order to make preparations in advance to prevent intraoperative bleeding and be caught off guard. The hemostatic function of human body is very important. When people are accidentally injured and bleed, the hemostatic function can play a role quickly, so that blood can be coagulated to stop bleeding and avoid bleeding.
Quantity loss. When a patient needs surgery, the doctor must know the patient's hemostatic function in advance. If the hemostasis function is not perfect, patients may bleed a lot during the operation, leading to surgical accidents and even death.
Four Concepts of Coagulation
Hypercoagulation, coagulation, bleeding and hemostasis are the most common clinical conditions. The screening and diagnosis of hemorrhagic diseases, the examination of prethrombotic state and thrombotic diseases, the correct application of various anticoagulants and prognosis estimation are all inseparable from the understanding of coagulation state. Four tests of coagulation can help doctors understand these problems accurately.
Four items of coagulation include
(1) Plasma prothrombin time (PT) and its derived international normalized ratio (INR);
(2) activated partial thromboplastin time (APTT);
(3) thrombin time (TT);
(4) plasma fibrinogen.
