Brief summary

Blood loss is a common complication of liver resection surgery. One intervention to reduce this is by lowering central venous pressure (CVP) by having the patient slightly head up. The limitation with this is that it is not CVP that effects blood loss but rather liver venous pressure. Although this is likely to be influenced by a patient's CVP, they are not the same pressure. We aim to see the relationship between position and hepatic venous pressures (measured by direct cannulation of the middle hepatic vein during surgery) as well as relationship between this pressure and the patient's CVP at the time of measurement.

Interventions

Changes in position during hepatic resection and its affect on hepatic venous pressure. Positions - 20 degrees head up, flat, 20 degrees head down
