The purpose of this study is to find out if direct peritoneal resuscitation (DPR) (putting a sugar solution into the abdominal cavity) helps blood flow through vital organs in the body that may suffer from low blood flow due to surgery. We will also try to find out if the DPR will help patients recover faster from liver surgery. Lastly, this study will also try to find if direct peritoneal resuscitation decreases levels of signaling chemicals in the blood called 'cytokines' and a protein called high-mobility group protein 1, which is known to cause tissue damage.
