Can we predict pulmonary wedge pressure from central venous pressure in hepatic transplantation?

Volume infusion is the main therapeutic option to optimize preload and tissue oxygen supply in distributive shock. Pulmonary capillary wedge pressure (Pw) has been used as the most important variable to predict preload in unstable hemodynamic patients. However, most patients are not monitored with pulmonary artery catheters, making central venous pressure the preload variable of choice. The literature has shown a moderate correlation between Pw and central venous pressure (CVP) in septic patients. As far as we know there are no data about this correlation in the postoperative period of hepatic transplantation.
