BLOOD LOSS
The time of the anhepatic phase, the time of surgery, blood loss, and the amount of transfused blood were recorded. The anhepatic phase began with the clamping of the IVC and ended with the opening of the IVC and PV. Transfusion volume is defined as the total volume of red blood cells, plasma, clotting factors, and transfused platelets. A decrease in the MAP ≥ 30% within 5 min, regardless of whether vasoactive drugs were used after PV reperfusion, was defined as postreperfusion syndrome (PRS). The total amount of 5% sodium bicarbonate infused during surgery was recorded. Arterial blood gas was collected and recorded before the start of surgery (T0), during anhepatic phase (T1), immediately after reperfusion of the transplanted liver (T2), and 30 min after reperfusion of the transplanted liver (T3).
