【 摘 要 】

All means to reduce blood loss in liver resection and to decrease blood loss and a need of blood transfusion would be of benefit to the patient as well as the surgeon. We report two cases in which different strategies were applied in order to achieve the low central venous pressure. We also compared in these cases surgical time, blood loss and blood transfusion requirements during liver resection.
