Objective To retrospectively analyze and evaluate the risk of whole blood exposure during component blood preparation, to provide evidences for formulating corresponding preventing and control measures, to reduce the risk of occupational exposure in component blood preparation staffand lower the waste of blood resources.Methods Calculate the total number of whole blood bags needed to be prepared and the number of whole blood bags discarded due to blood leakage incomponent blood preparation department annually during 2014—2017 in Guangzhou Blood Center Information System,and the data were analyzed in SPSS(22.0) software for χ~2 test and linear trend test. Results During 2014—2017, the total ratio of whole blood exposure in component blood preparation was 0.081% and the ratios of whole blood exposure due to blood leakage caused byheat sealing, blood bagquality and centrifugation were0.038%, 0.027% and 0.016%. Furthermore, the ratios of whole blood exposure of the three above types had statistically significant difference between the years respectively(P0.05).Meanwhile, the ratio of whole blood exposure due to blood leakage acused by heat sealing showed anincreasing trend(0.023%0.026%0.044%0.059%,P0.05). Conclusion The risk of occupational exposure in component blood preparation staff presented a rising trend and further precautions should be considered. Meanwhile the note of preventing occupational exposure should be strengthened constantly and the regulations should be compiled with and carried out strictly in Guangzhou Blood Center.
