Why is anticoagulation therapy used in hemodialysis patients?

Anticoagulation therapy is primarily used in hemodialysis patients to reduce clotting within the extracorporeal circuit. During hemodialysis, blood is drawn from the patient's body into a machine where it is filtered to remove waste products and excess fluid before being returned to the body. The equipment involved, including the tubing and dialyzer (artificial kidney), is susceptible to clot formation. If clots develop within this circuit, it can impede blood flow, reduce the effectiveness of the dialysis treatment, and potentially lead to complications for the patient.

By administering anticoagulants, healthcare providers can help maintain a smooth flow of blood throughout the dialysis process, ensuring that patients receive adequate treatment and minimizing the risk of interruptions due to clotting. Effective anticoagulation is a critical aspect of managing patients undergoing hemodialysis, as preventing clot formation directly contributes to better clinical outcomes and patient safety.
