Association Between the Use of Pulmonary Artery Catheter and Clinical Outcomes After Liver Transplantation

Pulmonary artery catheter (PAC) has been used for advanced hemodynamic monitoring during liver transplantation. However, recent advances in less invasive monitoring could provide continuous cardiac output monitoring by arterial waveform analysis. Using this technology, stroke volume variation (SVV) is monitored as a preload index. Calculated systemic vascular resistance (SVR) can be monitored if central venous pressure (CVP) is provided. Therefore, this less invasive form of hemodynamic monitoring may replace the PAC. The investigators attempted to evaluate whether the use of PAC is associated with better clinical outcomes after liver transplantation compared with the case without PAC.
