Abstract:
Objective To observe and analyze the influence of the improved ultra-low temperature storage box on the quality of fresh frozen plasma(FFP).Methods A total of 80 qualified whole blood samples(400 mL,O type not includ-ed)collected from July to November in 2023 were selected,and were divided into 4 groups,with 20 samples in each group.Group A:quick-frozen in a traditional low temperature box for 1 hour and then stored in a-30℃cold storage;Group B:quick-frozen in the flat freezer for 1 hour and then stored in a-30℃cold storage;Group C:quick-frozen in a newly im-proved ultra-low temperature storage box for 1 hour and stored in a-30℃cold storage;Group D:quick-frozen in a new im-proved ultra-low temperature storage box for 12 hours and stored in a-30℃cold storage.The contents of FⅧand fibrinogen(Fg)in four groups were detected.Results The contents of FⅧin group B,C and D were significantly higher than those in group A,with statistical difference(P＜0.05),but with no statistical difference among gourp B,C and D(P＞0.05),and no statistical difference in the contents of Fg was found among the four groups(P＞0.05).Conclusion The improved ultra-low temperature storage box is superior to the traditional low temperature box in preparing FFP,and there is no obvious difference between the improved ultra-low temperature storage box and the flat-plate quick freezer.However,the improved ultra-low temperature storage box can make the process of preparing FFP more flexible and improve the efficiency of compo-nent preparation.
