Outcome Measures

Primary Outcomes (1)

  • total perioperative allogenic transfusions of platelet and fresh frozen plasma

    on the 7th day postoperatively

Secondary Outcomes (2)

  • postoperative blood loss

    on the 7th day postoperatively

  • rate of reexploration for bleeding

    on the 7th day postoperatively

Study Arms (2)

APRP group

EXPERIMENTAL

APRP group is performed autologous platelet-rich plasma harvest technique before administration of heparin to the patient,the red blood cell(RBC) component is retransfused to the patient when the RBC transfusion protocol is reached,and the autologous platelet-rich plasma is transfused to the patient immediately after heparin is neutralized with protamine.

Device: Autologous Platelet-Rich Plasma Harvest Technique

control group

NO INTERVENTION

APRP group receive no autologous platelet-rich plasma harvest technique.

Interventions

15 to 20 mL/kg of whole blood is collected before the administration of heparin from a large-bore central venous access,and is separated into red blood cells component and autologous platelet-rich plasma component by an autologous transfusion system(Sorin Group Electa Essential; Sorin Group Italia, Milan, Italy).

Also known as: neutralizing heparin with protamine
APRP group
