Ammar Al Awawdeh: Bridging the Hemostatic Gap – Functional Platelet Salvage in CPB
Ammar Al Awawdeh, Senior Cardiovascular Perfusionist at Al-Ahli Hospital, Clinical and Business Strategy Consultant, Cardiovascular Perfusionist at Prince Hamzah Hospital, shared a post on LinkedIn:
“For years we’ve celebrated red blood cell recovery. Perhaps it’s time to ask a more important question: where did the platelets go?
In cardiac surgery, hemoglobin is far more than a laboratory value. It is the engine of oxygen delivery (DO₂), sustaining tissue metabolism throughout cardiopulmonary bypass.
CPB itself places the patient’s blood under extraordinary stress. Hemodilution lowers oxygen-carrying capacity, hypothermia alters coagulation, hemolysis releases free hemoglobin, acidosis impairs enzymatic clotting, while inflammation and mechanical shear activate and consume platelets.
Conventional cell salvage systems were engineered to recover washed red blood cells, not platelets.
As a result, the vast majority of platelets are removed during the washing process, leaving a critical gap in hemostatic preservation.
This is where SAME™ by i-SEP represents a genuine advance. It returns both Hemoglobin and one of the patient’s most valuable hemostatic assets: functional platelets.
The future of autotransfusion is no longer about recovering red blood cells alone.
It is about maximizing clinical value while minimizing the cost of bleeding, transfusion, and postoperative complications. Innovations that achieve both will define the next generation of Patient Blood Management.”
