AbstractIntraoperative harvest and transfusion back of platelet-rich plasma (PRP) are an effective procedure to decrease the requirement of blood transfusion. We selected the right atrium as the site for collection and transfusion back of the blood for the harvest of PRP. We studied changes of the hemodynamics and mixed venous oxygen saturation (SvO2 during the intraoperative harvest of autologous PRP in two patients who were undergoing cardiopulmonary bypass (CPB) surgery. The whole blood was collected, processed and the red blood cells were transfused immediately back to the patients using the Plasma Collection System (Haemonetics Model 50). The procedure was accomplished prior to starting CPB. The PRP product was transfused back into the patients at the completion of CPB. The arterial blood pressure, cardiac output, and SvO2 decreased during the collecting phase and immediately returned to the baseline values during the returning phase. No change was observed in the heart rate and arterial oxygen saturation. We conclude that the usage of right atrium as the site for collection and transfusion back of the blood to harvest PRP is effective and useful, and the continuous monitoring of SvO2 is mandatory for detecting the decline of the cardiac output.
