Low dose vasopressin given during liver transplantation prevents renal dysfunction in the perioperative period confirmed by evaluating creatinine postoperatively. baseline, 24 hours postop, 48 hours postop [clinicaltrials_resource:abeec3b8e64c46c929c69c8a5b1febae]

Patients randomly assigned to the experimental arm of the study will receive vasopressin 0.5U/hr IV (20 U vasopressin in 250mL of 0.9% NaCL to infuse at a rate of 6.25mL/hr) via internal jugular catheter. Vasopressin infusion is started at the time of incision and is stopped at the time abdominal closure is completed
