What is the role of heparin in dialysis?

Heparin plays a crucial role in dialysis by preventing blood clotting during the procedure. When blood is drawn from the patient's body for dialysis, it is exposed to artificial surfaces, such as those found in the dialysis machine. These surfaces can trigger the clotting process, potentially leading to complications such as occlusion of the dialysis circuit or reduced efficiency of the treatment.

By administering heparin, a medication that acts as an anticoagulant, healthcare providers can keep the blood flowing smoothly through the dialysis machine and prevent clots from forming. This allows for uninterrupted treatment and maximizes the removal of waste and excess fluid from the blood, ensuring the effectiveness of the dialysis process.
