Surgery puts a lot of stress on the body, and during recovery from surgery, the body uses a
lot of energy to help with healing and getting stronger. Often, sugars are given before
surgery to help give the body an energy boost. Lipid solutions can also be used as an energy
source and are commonly used as supplements in patients needing long-term nutrition from an
intravenous route (e.g., total parenteral nutrition) when they can not eat by mouth for a
medical reason. Intralipid, a solution of lipid molecules from soybeans and eggs, is commonly
used for patients who need nutrition and energy supplements. The investigators wish to test
whether giving Intralipid immediately after surgery can improve recovery from major surgery.
