Changes of coagulation function and other indicators of the thawed FFP and FLP at 2-6℃

Abstract

Objective To observe the changes of coagulation factor activity and protein content of the thawed fresh frozen plasma (FFP) and fresh liquid plasma (FLP) during storage at 2-6℃, and to provide reference for exploring the appropriate storage time of FFP at 2-6℃ after thawing. Methods The small-thaw group and the large-thaw group were respectively detected for the activity of coagulation factor FⅤ (FⅤ∶C) and FⅧ(FⅧ∶C), and the levels of fibrinogen (Fib), total protein (TP) and albumin (Alb) in TTP at 1, 2, 3, 4, 5, 6 and 7 days after thawing. And the FLP was detected for FⅤ∶C, FⅧ∶C, Fib, TP and Alb at 1, 2, 3, 4, 5, 6, 7 days and 1, 6, 11, 16, 21, 26 and 31 days after preparation, respectively. Results In FFP group, FⅧ∶C decreased gradually with the prolongation of storage time after melting (P0.05). In FLP group, FⅧ∶C decreased gradually with the prolongation of storage time after melting (P0.05), but it decreased gradually in 31-day storage group (P0.05). Conclusion Although FⅧ∶C is decreased in thawed FFP stored at 2-6℃ for 7 days, it is still about 52.4%, which should be able to play a normal role in clinical practice.
