Abstract
Objective:To analyze the causes and countermeasures of red blood platelet collection by MCS++blood cell separator in Lanzhou area.Methods:A total of 90 blood donors who underwent plateletpheresis in Lanzhou area from December 2022 to December 2024 were enrolled in this study.Platelet collection was performed using the MCS+blood cell separator(Haemonetics,USA)with Haemonetics REF 0996 E-00/996 E2-00 tubing sets.The subjects were divided into two groups according to whether red flashing occurred during collection:70 cases in the non-red-flashing group(no red flashing)and 20 cases in the red-flashing group(red flashing occurred).Pre-collection blood cell counts were compared between the two groups.Results:Among 90 blood donors,20 cases were red-washed,and the incidence of red-washed was 22.22%.The red blood cell count(RBC)、mean red blood cell volume(MCV)、red blood cell volume(Hct)、hemoglobin(Hb)、mean hemoglobin content(MCH)and mean red blood cell hemoglobin concentration(MCHC)in the red blood flushing group were lower than those in the red blood flushing group(P<0.0 5).However,there were no significant differences in white blood cell count(WBC)、platelet count(PLT)、platelet volume distribution width(PDW)、average red blood cell distribution width(RDW)、average peripheral blood platelet volume(MPV)and large platelet ratio(P-LCR)between the two groups(P>0.05).Conclusion:The reason of red blood platelet collected by MCS+blood cell separator in Lanzhou area is that the values of RBC、Hb、Hct、MCV、MCH and MCHC in blood cell count before blood collection are low.The blood collection department of blood station should take effective measures against the above reasons,such as reducing the blood collection speed appropriately and keeping it stable,so that blood cells can be fully stratified between lay-ers during centrifugation,and the optical detector of blood cell separator can effectively identify platelets,thus im-proving the efficiency of platelet collection and reducing red blood platelet when plasma passes through the pipeline sensor.关键词
