RETROGRADE PRIMING or REVERSE AUTOLOGOUS PRIMING.

This is a video demonstrating how to do retrograde priming or reverse priming. Retrograde priming involves removing excess fluid in the cpb circuit and also using the patient’s arterial blood to displace crystalloid prime in the arterial line, venous line, or oxygenator backward (retrograde). This is done just before initiating CPB, once arterial and venous cannulas are in place. ✅ Purpose / Benefits 1. Reduces hemodilution → higher hematocrit during CPB 2. Decreases transfusion requirements 3. Improves oxygen-carrying capacity 4. Reduces tissue edema 5. Decreases priming volume, especially helpful in pediatric and small adult patients. Kindly Note: Once the excess volume in reservoir is removed you can unclamp the arterial line (keeping in mind the systemic pressures) and the fluid from the arterial line will also be displaced back into your retrograde containing IV bottle/reservoir. Caution⚠️ : Observe systemic pressures mandatorily during retrograde/reverse autologous priming. To be avoided during cases of hypotension.
