Popis: Introduction. Accurate blood pressure (BP) measurements are the mainstay for the efficient management of abrupt changes of hemodynamics and perfusion during orthotopic liver transplantation (OLT).Material and methods. The prospective study included 39 patients. We compared the BP values measured in the femoral and radial arteries during the different phases of the OLT.Results. The central systolic arterial pressure (SAP) and mean arterial pressure (MAP) measured invasive in the femoral artery were significantly higher than those measured in the peripheral artery during the anhepatic phase (95.1±10.6 vs. 84.5±9.9 mm Hg, and 66±8.8 vs. 59.7±7.1 mm Hg, respectively), after 5 minutes of reperfusion (91.1±17.3 vs. 78.5±18.4 mm Hg, and 63.9±13.1 vs. 57.7±13.6 mm Hg, respectively), and after 15 minutes of reperfusion (102.2±16.8 vs. 88.1±14.4 mm Hg, and 67.7±10.7 vs. 62.5±10.4 mm Hg, respectively). We found a strong correlation between the differences of SAP and MAP and the dose of norepinephrine administered during the anhepatic phase (r=0.76 and r=0.77 for SAP and MAP, respectively), and after 5 minutes of reperfusion (r=0.71 and r=0.52 for SAP and MAP, respectively). The difference between central and peripheral BPs after 15 minutes of reperfusion mainly depended on the changes in the potassium concentration (r=0.55 for SAP and MAP) and base deficiency (r=0.73 and r=0.82 for SAP and MAP, respectively).Conclusion. Thus, it was proved that the invasive measurement of BP in the femoral artery is a more accurate method compared with that in the radial artery as it is less exposed to high doses of vasopressors and variations in the acid-base state during OLT.
