Abstract:
Objective To investigate the feasibility of leucocyte-reduced pooled platelet concentrates from whole blood stored at 4℃,and provide theoretical basis for the components preparation.Methods The collected 400 mL ACD-B antico-agulant whole blood was randomly divided into two groups,stored at 4℃and room temperature.The buffy coat was prepared within 6 hours and store at 22℃until next day to prepare leucocyte-reduced pooled platelet concentrates.Platelet samples on day 1,3,5 and 7 were taken for the blood cell count and related parameter detection.The pH,glucose and lactic acid con-tent were determined to reflect the metabolic status,and the thromboelastography,platelet aggregation rate and PAC-1 and CD62P expression were determined to reflect the function and activation of platelets.The difference in platelets between two groups were analyzed.Results With the extension of storage time,the count of leucocyte-reduced pooled platelet concen-trates decreased gradually,but the platelets distribution width(PDW),mean platelet volume(MPV)and platelet-larger cell ratio(P-LCR)increased gradually in two groups,with no statistical significance(P＞0.05).The pH and glucose con-tents in two groups gradually decreased,but the lactic acid content gradually increased,with no significant difference(P＞0.05).The thrombelastogram showed MA value that reflecting platelet function has no significant change during the storage,and there was no significant difference between the two groups(P＞0.05).The aggregation rates decreased while the expres-sion of PAC-1 and CD62P increased gradually with the prolongation of preservation time,with no significant difference be-tween the two groups(P＞0.05).Conclusion There is no significant difference in platelet count,function and activation between whole blood stored at 4℃and at room temperature within 6 hours.Whole blood stored at 4℃within 6 hours can be considered as the raw material for leucocyte-reduced pooled platelet concentrates.
