High low mean arterial pressure target in liver transplant patients. An open, controlled, single-center, randomized clinical trial - Protocol and methods (LIVER-PAM).

Objective: To explain the rationale and protocol of the methods and analyses to be used in the LIVER-PAM randomized clinical trial, which seeks to understand whether a higher mean arterial pressure is capable of reducing the incidence of renal dysfunction postoperatively after liver transplantation.

Methods: LIVER-PAM is an open-label, randomized, controlled, singlecenter clinical trial. Patients randomized to the intervention group will have a mean arterial pressure of 85 - 90mmHg in the initial 24 hours of postoperative management, while patients in the control group will have a mean arterial pressure of 65 - 70mmHg in the same period.
