Background technique

In hemodialysis treatment, it is necessary to use anticoagulants to ensure the normal function of extracorporeal circulation. Anticoagulation is an important part of hemodialysis. During the period, it is easy to aggravate the bleeding tendency. In recent years, in vitro citrate anticoagulation technology has been used in hemodialysis, especially for patients with obvious bleeding tendency who need hemodialysis in the perioperative period. It is of great significance to prevent bleeding; The use of citric acid for in vitro anticoagulation in dialysis plays a significant role in the coagulation mechanism. The use of citric acid in the circulation pipeline during hemodialysis can bind calcium ions to form a calcium citrate complex, which reduces the concentration of calcium ions. Prolong blood clotting time and reduce the incidence of blood clotting. At the end of hemodialysis, calcium ions should be added to prevent the occurrence of hypocalcemia and improve the effect of hemodialysis. Studies have shown that the use of extracorporeal citrate anticoagulation technology for hemodialysis is safe and reliable, and the bleeding risk is significantly lower than heparin in vivo anticoagulation. Clinical promotion and application, especially for patients with clear bleeding tendency and postoperative dialysis.
