ABSTRACT
Objective In order to improve blood donors to understand the health education knowledge,this study designed and evaluated a new project,that is the health education pathway for primary apheresis donors.Methods A total of 2900 primary apheresis donors participated in the current study,who were randomly divided into the experimental group and the control group.The experimental group was performed the health education pathway for primary apheresis donors,while the control group was conducted in the traditional health educational ways.We compared the basic information,the awareness rate of apheresis donation knowledge,the number of regnlar/repeated donors,and the frequency of donations.Results Two groups were matched with no group differences in basic information (P＞0.05).After performed the health education pathway for primary apheresis donors,the awareness rate of apheresis donation knowledge was significantly improved from 23.6％ to 84.3％ (P＜0.01).Moreover,the percentage of regular donors (40.2％) in the experimental group higher than the percentage (26.7％) in the control group(P＜0.01).The average donation times of experimental group (3.8) was also higher than the control group.There were 79.2％ donors changed to regular/repeated donors higher than the percentage (66.4％) in the control group,and the average frequency of apheresis of those regular/repeated apheresis donors (7.4) in the experimental group higher than the control group (6.4) (P＜0.01).Conclusion As showed in our results,the health education pathway for primary apheresis donors could effectively help donors to understand the knowledge of blood donation and health care,and promote team construction of regular donors.We hope,in the future,the health education pathway for primary apheresis donors could be widely spread.
ABSTRACT
Objective To investigate the quality of concentrated platelet with less WBC by improved white membrane method,so as to provide the basis for preparation of the concentrated platelet in the future.Methods Testing the quality indicators of 56 cases of concentrated platelet with less white blood cells by improved white membrane method,and comparing the quality indicators of 56 cases of collected platelet at random by machine.Testing the expression rate of platelet membrane surface glycoprotein molecules CD62P and PAC-1 before and after filtering in different storage time,and comparing the expression rate of 37 cases of collected platelets at random by machine.Results The differences of quality indicators between concentrated platelet with less white blood cells by improved white membrane methods and collected platelet at random by machine were not statistically significant (P＞0.05),such as volume,platelet content,Ph,amount of RBC mixed within.But The differences of amount of WBC mixed with were statistically significant (P＜ 0.01),both of sterility tests were negative.The differences of the expression rate of platelet membrane surface glycoprotein molecules CD62P and PAC-1 during storage period within 3 days were not statistically significant (P＞0.05).Conclusion The various quality indicators of concentrated platelet with less white blood cells by improved white membrane methods attain mixed concentrated platelet and platelet national standards,and in vitro platelet activity kept well.Platelet special leucocyte filter does not cause obvious platelet activation and damage within three days of storage period of concentrated platelet in filter processing.Collected platelet by machine is being activated and damaged continuously when kept in platelet oscillation device 22±2℃ for 3 days,but activation and damage does not significantly change the platelet activity in vitro.
