Primary Outcome Measures

Name	Time	Method
Hepatic venous pressure - as measured via a 23 gauge cannula inserted into the middle hepatic vein prior to hepatic resection[Three measurements in each position (head up, flat, head down). Two minutes will separate each measurement.]

Secondary Outcome Measures

Name	Time	Method
The relationship between hepatic vein pressures and central venous pressures (CVP). Traditionally, CVP is measured and interventions are made to lower this pressure. However, it is the intra-hepatic venous pressure that is more important in preventing blood loss during resection. We will correlated the measured intra-hepatic pressure with the patient's CVP at that time.[Each of the three measurements will be compared with the central venous pressure at the time of measurement.]
