Objective To explore ability of deformation ,small deformation, orientation and in vivo half-life of erythrocytes following intraoperative autotransfusion by ZITI-3000 cell saving system (Jingjing medical facility corporation, Beijing). Methods Twenty consecutive patients undergoing scheduled off-pump coronary artery bypass grafting (CABG) were divided into two groups according to intraoperative autotransfusion, experimental group(n=10): intraoperative autotransfusion was performed; control group (n=10): intraoperative autotransfusion wasn’t used. Laser diffractometer was used to measure deformation index(DI), small deformation index[(DI)d.max], and orientation index [(DI)or.max],and chromium51 istope labeling technique was used to measure half-life of erythrocytes (51C1/2) of processed and unprocessed in vivo. Results There were no significant difference in DI, (DI)d.max, (DI)or.max and 51C1/2 in vivo between experimental group and control group. Conclusion Intraoperative autotransfusion has no significant effect on erythrocytes’s ability of DI, (DI)d.max, (DI)or.max and 51C1/2 in vivo in off-pump CABG.
