Brief Summary

The purpose of this study is to determine the efficacy and safety of Angiotensin II as a second-line vasopressor (drug that raises the blood pressure) during liver transplantation.

Detailed Description

This is a single center, randomized, double-blind, placebo-controlled trial. Subjects will receive an infusion of either Angiotensin II (AngII) or a saline control (placebo) in addition to usual care ...
