Objective:
To evaluation the clinic effects of intraoperative autotransfusion with the blood recovery-therapy instrument.
Methods:
Intraoperative autotransfusion with the blood recovery-therapy instrument was performed in 116 operations from Aug 2000 to Nov 2001. The hemocytology, the markers of liver and renal function, blood coagulation and the total amount of drain after operation were analyzed.
Results:
The autotransfusions were all successful. The levels of HCT, RBC, Hb in processed blood were significantly higher than in the recovered blood, while the PLT was much lower than in the recovered blood. The temperature tendency after intraoperative autotransfusion was in coincidence with the law of reaction after normal operation. The levels of RBC, Hb, WBC and HCT decreased one day and one week after operation compared with those before operation. Although the level of PLT decreased one day after operation, it recovered one week after operation. The levels of ALT, AST, total protein(TP) and BUN were markedly lower in processed blood than in recovered blood. TP was decreased one day after operation, but restored one week after operation. The other markers of liver and renal function did not change during the peri-operation. The clearance to heparin of the process was (96 +/- 0.6)%. ACT and total amount of drain after operation did not alter obviously.
Conclusion:
Practice of intraoperative autotransfusion with the blood recovery-therapy instrument can reduce the demand of allogenic blood effectually, and the occurrence of complications after operation.
