Perioperative Use of Amino Acids in Recipients of Orthotopic Liver Transplantation as a Renal Protective Factor

Adult patients scheduled for orthotopic liver transplant to receive an intravenous infusion of a mixture of amino acids including L arginine, at a dose of 2 g per kg of ideal body weight up to a maximum of 100 g per day, from their admission to the operating room until three days after surgery; the infusion will begin in the operating room prior to the start of the surgery, will be administered through an exclusive lumen of a central venous catheter (CVC) immediately after the CVC is in place; the infusion will continue when the patient is in the intensive care unit (ICU); as soon as the patient begins enteral nutrition, the infusion will be reduced to meet the dose of 2 g per kg of protein intake per day up to a maximum of 100 g daily, until completing 72 H of infusion. The Control Group consists of previously transplanted patients at this institution who did not receive this type of therapy.
