When transfusing blood during heparin-free dialysis, what complication should be monitored?

When transfusing blood during heparin-free dialysis, monitoring for increased viscosity of the blood is crucial. Heparin is typically used to prevent clotting during dialysis, and in the absence of it, there may be a significant increase in blood viscosity due to the high concentration of red blood cells in the transfused product. This increased viscosity can lead to compromised blood flow through the dialysis circuit and result in potential complications such as inadequate dialysis treatment, increased workload on the heart, and even thrombotic events.

Understanding the dynamics of blood transfusion and its interaction with hemodialysis parameters emphasizes the importance of careful monitoring. Increased blood viscosity can also affect the patient's overall hemodynamic stability, potentially leading to changes in blood pressure and heart rate. Therefore, vigilance in observing for signs and symptoms associated with increased blood viscosity during the procedure is essential for patient safety and effective dialysis management.
