Tacrolimus During the Implantation and the Effect on Ischemia-Reperfusion Injury in Liver Transplantation - Full Text View

Purpose

The evaluation of the efficacy of an intraportal infusion with Tacrolimus, at the time of liver graft implantation, compared to a control group without immunosuppressive intraportal infusion (Placebo: Saline solution 0.9%) with respect to the initial liver function measured by the parameters of the liver function (LFP): AST (U/L), ALT (U/L), total Bilirubin (mg/dL) and the coagulation factors: NT (%), PTT (s), INR.
