[Perfusion management in liver transplantation].
Veno-venous bypass (VVB) with a Biopump centrifugal pump (Biomedicus, USA) was used in 36 patients with liver diseases during orthotopic transplantation of the liver. Volume rate of perfusion (VR), systolic, diastolic, and mean arterial pressure (AP), and central venous pressure (CVP) were monitored. VR during liver-free period was 850-1350 (1064.2 +/- 87.5) ml/min in femoral-axillary bypass and 1700-3500 (2630.5 +/- 112.3) ml/min in femoral-porto-axillary bypass. A trend to a decrease of the mean AP to 65 mm Hg was observed at the end of liver-free period (p < 0.05), while CVP decreased to 2 mm Hg (p < 0.05); there was a trend to a moderate tachycardia. No significant shifts in acid-base balance, oxygen balance, and blood electrolytes were observed during the liver-free period. Maximum blood loss occurred during the liver-free period and reperfusion of the transplant. Blood loss was evaluated by the amount of washed autoerythrocytes obtained after processing of collected blood in the Cell-Saver device. VVB had a favorable impact on the course of orthotopic transplantation of the liver, maintaining stable hemodynamic and biochemical parameters and preventing ischemia of the abdominal organs. Preservation of autoerythrocytes by the Cell-Saver device minimized the need in donor erythrocytes, thus ruling out the complications associated with homologous blood transfusion.
