In Japan, neither fibrinogen concentrate nor cryoprecipitate (CRYO) is available for cases of acquired hypofibrinogenemia to recover the hemostatic level of fibrinogen rapidly. We prepared and produced in-house CRYO from fresh frozen plasma, and compared mortality between pre-implementation and post-implementation of CRYO. Methods: We performed a retrospective cohort study of patients admitted to our single tertiary medical center with upper GI bleeding from January 2011 to December 2016. The observational control period was from January 2011 to February 2013. From March 2013 to December 2016, we implemented the transfusion of CRYO, which was prepared and produced in our hospital. Clinical outcomes were compared between the patients in the two periods. Patients: Eleven patients in the control period and 10 in the intervention period were eligible for analysis. Results: In-hospital mortality (55% vs. 20%, P = 0.238) and mortality within 24 hour after admission (27% vs. 0%, P = 0.246) tended to be lower in the intervention period than in the control period, although the patients had more severe coagulation on admission than those in the control period. The plasma fibrinogen level before the treatment of hemostasis in the intervention period was higher than that in the control period (80 ± 9 mg/dL vs. 127 ± 15 mg/dL, P Conclusion: Implementation of in-house CRYO transfusion may reduce the rate of mortality due to severe upper GI bleeding.展开更多
