Description of intervention(s) / exposure
Cardiac output measurments by a Swan-Ganz catheter (pulmonary artery catheter) is gold standard method in present despite its reported inaccuracies and drawbacks. The alternative tool, FloTrac/Vigileo system (arterial pressure waveform analysis), has the advantage of being inherently less invasive. This is an observational study intraoperatively to evaluate the upgraded third-generation software (version 3.02) for the FloTrac/Vigileo system. This latest version has been developed to particularly improve the accuracy of cardiac output measurements in hyperdynamic conditions. The aim of our prospective study was to compare the cardiac output values obtained using the FloTrac/Vigileo system during orthotopic liver transplantation with those obtained in the same circumstances using a Swan-Ganz catheter (bolus thermodilution method) within 6 months period.

Accuracy of the upgraded third-generation software (version 3.02) for the FloTrac/Vigileo system
For statistical analysis, we will use the linear regression, Bland-Altman analysis, bias, 95% limits of agreement, and percentage error between COTh and COFT measurements for analysis.

Summary
Brief summary
The FloTrac/Vigileo software was upgraded to version 3.0+ in 2008 to improve the inaccurate cardiac output measurments in hyperdynamic conditions. More patients were recruited to develop the algorithm database than were used for the second-generation software, including more patients with hyperdynamic conditions. If this system really is interchangeable with the gold standard bolus thermodilution method that requires PAC catheterization, it may decrease fatal complications in those recipients who are fragile and immunocompromised during the surgery.
