At the end of surgery (T1), both TIVA-TCI and AR-13324 manufacturer BAL patients showed a marked and significant increase in pro-coagulant factors (TAT, F1 + 2 and FVIII) and consequent reduction in haemostatic system inhibitors (AT, PC and PS) compared to the values measured prior to surgery (p ≤ 0.004 for each markers). The greatest increase was observed in the values of TAT and F1 + 2 (about 3 times compared to T0), while the values of FVIII

increased approximately 30%. F1 + 2 and FVIII slightly reduced at T2 but remained Cell press significantly higher than basal levels (p ≤ 0.04 for each markers). Only TAT values returned to pre-anaesthesia values. We observed a corresponding increase in anti-coagulant factors that remains significantly lower than prior to surgery (p = 0.001). Fibrinogen levels significantly decreased at T1 in comparison to the initial values, but rose significantly 24 hours post-surgery in both groups, showing an increase of about 20-30% as compared to T0 values (p = 0.001). Changes in pro-coagulant factors and haemostatic system inhibitors were similar in both TIVA-TCI and BAL patients with no significant differences between the two groups of patients. In regards to the fibrinolysis system, D-dimer concentration in TIVA-TCI group, levels increased about 6-fold at T1 compared to baseline level (p = 0.001, Table 3), while in BAL patients it showed an increase of about 4-fold (p = 0.001, Table 4). Both groups showed a decrease of D-dimer at T2 even if the concentration remained higher than baseline levels (p = 0.001), with no significant differences between TIVA-TCI and BAL patients. Levels of the PAI-1, the principal inhibitor of the fibrinolysis system, and D-dimer remained constant between T0 and T1 but significantly increased at T2 in both groups.
