Trial size 80 participants
Trial identifier NCT02513862, 2014-zx011


The purpose of this study is to determine whether autologous platelet rich plasma (APRP)is effective in reducing allogeneic blood transfusions during aortic surgery using deep hypothermic circulatory arrest.

Study Design

Allocation randomized
Intervention model parallel assignment
Masking single blind (subject)
Primary purpose prevention
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.
autologous platelet-rich plasma harvest technique neutralizing heparin with protamine
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).
(No Intervention)
APRP group receive no autologous platelet-rich plasma harvest technique.

Primary Outcomes

total perioperative allogenic transfusions of platelet and fresh frozen plasma
time frame: on the 7th day postoperatively

Secondary Outcomes

postoperative blood loss
time frame: on the 7th day postoperatively
rate of reexploration for bleeding
time frame: on the 7th day postoperatively
