Preoperative predictors of blood transfusion in liver resection for tumor.
BACKGROUND
Hepatic resection remains a hemorrhagic procedure. The purpose of this study was to investigate the preoperative predictive factors of intraoperative blood transfusion.


METHODS
One hundred consecutive patients who underwent hepatic resection for tumor were included in this retrospective study. Resection was performed for primary malignancies (n = 52), metastases (n = 18), and benign tumors (n = 30). Liver resection was performed under intermittent clamping of the portal triad. Seventeen variables were analyzed.


RESULTS
The operative blood loss was 1,872 mL (mean 1,104; range 650 to 4500) for the 22 transfused patients. The mean blood transfusion was 5.5 units (mean 3.2; range 2 to 12) of packed red cells. Multivariate analysis demonstrated that the size of liver resection (P <0.001) and the prothrombin rate (P <0.001) were independently correlated with blood transfusion.


CONCLUSIONS
Patients undergoing extended resection or with abnormal coagulation could be considered for autologous blood transfusion.
