In a randomized study of 132 consecutive patients undergoing liver transplantation, we found that tranexamic acid, but not epsilon-aminocaproic acid, reduced intraoperative total packed red blood cell transfusion.

GOS scores improved between 6-12 months after severe TBI in 36% of survivors and it is concluded that the expectancy of improvement is incomplete at 6 months. This improvement was greater in patients with better GCS scores (6-8) at admission than in those with worse GCS scores (3-5).

Fibrinolysis has been recognized as an important cause of intraoperative bleeding during orthotopic liver transplantation (OLT). Several investigators have used prophylactic administration of aprotinin in patients to inhibit fibrinolysis and to decrease transfusion requirements, morbidity, and mortality. Nevertheless, the role of aprotinin in this situation is not yet clear. The goal of this study was to determine the effects of prophylactic administration of aprotinin on intraoperative bleeding and blood requirements, and on hemostatic changes during OLT. Eighty consecutive patients were included in a double-blind, prospective study and were randomized in two groups. In group A (n = 39), an initial dose of 2 x 10(6) kallikrein inactivator units (KIU) of aprotinin was administered in the induction of anesthesia followed by infusion of 5 x 10(5) KIU/h until the end of the procedure. The control group (n = 41) received an identical volume of saline solution. The majority of the operations were performed with vena cava preservation (piggy-back technique) without venovenous bypass. During the anhepatic phase, a significant increase in levels of tissue plasminogen activator, thrombin-antithrombin complexes (TAT) and D-dimers (DD) was noted in both groups. A significant increment of TAT was observed in group A during reperfusion. The remaining hemostatic parameters were similar in both groups. Intraoperative requirements of packed red cells, fresh-frozen plasma (FFP), platelets, and cryoprecipitate were similar in the two groups. Our results suggest that prophylactic administration of aprotinin is not useful in reducing bleeding and blood product requirements during OLT.

TCDB CT scan classification and subarachnoid haemorrhage were associated with GOS/GOSE improvement from 6-12 months, but individual CT abnormalities were not associated.
