抗凝治疗,既是一种治疗疾病的措施,也是一种预防血液凝固的措施。但抗凝剂的采用,必须有效地加以监护,否则将会引起出血。人体血液内既有抗凝因子,也有使血液凝固的因子。正常情况下两者保持平衡,一旦维持平衡的条件发生变化,扰凝系统占优势,引起组织出血;凝血系统占优势,会造成血管内血栓形成。 Anticoagulant therapy, both a measure of disease treatment, but also a measure to prevent blood clotting. However, the use of anticoagulants, must be effectively monitored, otherwise it will cause bleeding. There are both anticoagulant factors in human blood and blood coagulation factors. Under normal circumstances the balance between the two, once the balance conditions change, the scramble system dominant, causing tissue bleeding; coagulation system dominant, will cause intravascular thrombosis.
