Study of the reasons of red blood cell spillover in thrombocytapheresis

Objective To study the reasons of red blood cell spillover in thrombocytapheresis by MCS+type blood cell separator. Methods 15 blood donors with red blood cell spillover were selected as the observation group,while 20 blood donors without red blood cell spillover were selected as the control group in synchronization of our blood center.To analyze the reasons of red blood cell spillover and to compare the blood cell count of RBC,Hb,Hct,MCV,MCH and MCHC and etc between the two groups. Results It was found by detection that,the various blood cell counts were lower in observation group than which in control group,the differences was statically significant(P 0.05).It was found by statistics the reasons of red blood cell spillover were that,the various blood cell counts of MCV,MCH and MCHC were lower in 11 blood donors than normal persons,there were 2 cases in psychentonia and 2 cases in fat blood. Conclusion The red blood cell spillover which caused by much reasons could influence the platelet quality and delay the rescue of patients.To select the qualified blood donors through the plasma-derived,the physical examination,the chemical examination and the acquisition in each link,to remissive and reduce the incidence,to improve the platelet quality,in order to guarantee the transfusion safety.
