Abstract:
This study was aimed to evaluate the efficiency and effectiveness of platelet-rich plasma(PRP) prepared by acute plateletpheresis in patients undergoing open heart surgery, and to analyze the quality of prepared platelet-rich plasma. Whole blood from 20 patients with ASAII-III was collected and PRP was harvested by machine after induction of anesthesia. Platelet count (Plt), mean platelet volume (MPV), platelet distribution width (PDW), plasma pH, plasma lactic acid (LA) concentration, and lactic dehydrogenase (LDH) concentration, germiculture result, CD62p and PAC-1 positive rate of inactivated and activated platelets by ADP in the whole blood before plateletpheresis (T1) , in the PRP after plateletpheresis (T2) and PRP before back-transfusion (T3) were determinated. The results showed that as compared with whole blood the platelet count in the PRP at T2 was (783 ± 184) ×10(9)/L, MPV, PDW and pH significantly decreased (P < 0.01) , while the plasma LDH, LA concentration, CD62p and PAC-1 positive rate of inactivated platelets were not significantly different from the whole blood at T1. In the PRP at T3, the platelet count, MPV, PDW and pH significantly decreased (P < 0.01) , while plasma LDH concentration, CD62p and PAC-1 positive rate of inactivated platelet significantly increased (P < 0.05 or P < 0.01) compared with the whole blood at T1. There were no significant difference among the CD62p and PAC-1 positive rate of activated platelets in the whole blood and PRP. It is concluded that PRP can be efficiently obtained from the patients undergoing open heart surgery by acute plateletpheresis, and the platelets in PRP are not activated during the preparing process. Some platelets in PRP are activated during the preserving process, but the whole activating function of platelets keeps normal.
