Hemodialysis is a kind of cardiopulmonary bypass treatment. Anticoagulant should be applied to prevent blood from coagulation during cardiopulmonary bypass, which is also a necessary guarantee for the smooth progress of hemodialysis treatment. At present, heparin and low molecular weight heparin are commonly used anticoagulants in hemodialysis.
How does heparin use, use much a lot of appropriate? This is often related to the patient, the general dialysis is using systemic heparinization, that is, the first dose is given, and then the maintenance is given every hour, each patient's heparin dose is very different and must not be the same. Heparin dosage is not enough, will occur in vitro coagulation, each dialysis will lose a small amount of blood, which is also one of the causes of anemia in dialysis patients; Excessive use of heparin is associated with the risk of bleeding, especially in patients who are prone to bleeding. This requires dialysis nurses to strictly observe whether there is blood clotting and the degree of blood clotting in the dialyzer and pipeline, timely communication with doctors, adjust the use of heparin.
Generally speaking, heparin is the most commonly used and relatively safe anticoagulant, suitable for most dialysis patients, but heparin also has some adverse reactions, including allergy, itching, osteoporosis, hyperlipemia, thrombocytopenia, and excessive bleeding. However, the sensitivity of different patients to heparin is different, and the sensitivity of the same patient to heparin will be different over time, so it cannot be uniform. For patients with more adverse reactions to heparin, other anticoagulation methods may be considered.
Heparins Manufacturer: For the prevention and treatment of thrombotic or embolic diseases such as myocardial infarction, thrombophlebitis, pulmonary embolism, etc. Diffuse intravascular coagulation (DIC) caused by various causes; Also used in hemodialysis, extracorporeal circulation, catheterization, microvascular surgery and other operations and some blood specimens or instruments anticoagulation treatment.
