INTRODUCTION Blood transfusion is associated with increased morbidity and mortality. We developed and implemented an algorithm for coagulation management in cardiovascular surgery based on first-line administration of coagulation factor concentrates combined with point-of-care thromboelastometry/impedance aggregometry. METHODS In a retrospective cohort study including 3,865 patients, we analy...

Results Of 300 patients enrolled, 50 received 4 or more units of PRBCs. On average, patients with high admission lactates (>=5.0mmol/l) did not clear their lactate until blood transfusion had stopped and haemorrhage was controlled (p <0.05. Figures A and B – patients receiving 4 and 8 units of PRBCs). Patients who normalised their lactate levels prior to the end of transfusion had significantly...

Irradiation of blood components with ionizing radiation generated by a specific device is recommended to prevent transfusion-associated graft-versus-host disease. However, a linear accelerator can also be used in the absence of such a device, which is the case of the blood bank facility studied herein. In order to evaluate the quality of the irradiated packed red blood cells, this study aimed t...

Background The concept of massive transfusion was developed to trigger clotting factor therapy for the treatment of coagulopathy due to dilution, after a certain number of units of packed red blood cells. It has been defined as the replacement of circulating volume or the transfusion of more than 6 or 10 units of packed red blood cells (PRBC) in the 24 hours after injury. Until recently there h...

BACKGROUND Blood warmers were developed to reduce the risk of hypothermia associated with the infusion of cold blood products. During massive transfusion, these devices are used with compression sleeve, which induce a major stress to red blood cells. In this setting, the combination of blood warmer and compression sleeve could generate hemolysis and harm the patient. We conducted this study to ...

The preservation of red cells "hard packed" to a hematocrit of over 80% from blood collected in citrate-phosphate-dextrose (CPD) or CPD-adenine (CPDA-1) has been investigated. After 21 days of storage, cells that had been collected in CPD solution had consumed most or all of the available glucose and manifested markedly impaired viability after reinfusion into the normal donor. In contrast, red...

In this study, we report the first Korean case of an anti-Gerbich (Ge) alloantibody to a high-incidence antigen that belongs to the Ge blood group system. The alloantibody was detected in a middle-aged Korean woman who did not have a history of transfusion. Her blood type was B+, and findings from the antibody screening test revealed 1+ reactivity in all panels except the autocontrol. The cross...
