What is the role of anticoagulants during hemodialysis?

The role of anticoagulants during hemodialysis is primarily to prevent blood clotting in the circuit. During the dialysis procedure, blood is circulated through the dialysis machine, which includes various components like the dialyzer and tubing. If clotting were to occur in these areas, it could severely disrupt blood flow, reduce the efficiency of toxin removal, and compromise patient safety.

Anticoagulants, such as heparin, are employed to ensure the blood remains fluid as it moves through the system, allowing for optimal dialyzer function and maximizing the removal of toxins and excess fluid from the blood. By preventing clot formation, anticoagulants contribute to maintaining the necessary flow rates and overall functionality of the dialysis process, which is critical for effective treatment outcomes.
