Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures
NameTimeMethod
Number of Participants with acute kidney injurythe first 7 postoperative days

Acute kidney injury (AKI) was defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria, which was defined according to the greatest change in serum creatinine level during the postoperative seven days (Stage 1: more than 1.5-fold; stage 2: more than 2-fold; stage 3: more than 3-fold increase from baseline level or increase in serum creatinine to ≥ 4.0 mg/dL or the initiation of renal replacement therapy). The most recent serum creatinine level measured before surgery was collected as a baseline value.

Number of Participants with early allograft dysfunctionthe first 7 postoperative days

Early allograft dysfunction (EAD) was defined when one or more of the following are present within the first 7 postoperative days: total bilirubin ≥ 10 mg/dL, prothrombin time: international normalized ratio ≥ 1.6, or aspartate or alanine transaminase \> 2000 IU/L
