Avoiding Recooling After Normothermic Machine Perfusion in Liver Transplantation (ARANMP-LT)
Avoiding Recooling After Normothermic Machine Perfusion in Liver Transplantation: a Multicenter, Parallel-group, Open-label, Non-inferiority Randomized Controlled Trial
The ARANMP-LT study is a multicenter, open-label, randomized, parallel-group, non-inferiority clinical trial designed to evaluate whether avoiding graft recooling after normothermic machine perfusion (NMP) improves early outcomes following liver transplantation. Although graft recooling before implantation is common practice, experimental and preliminary clinical evidence suggests that abrupt temperature changes may contribute to ischemia-reperfusion injury.
Adult recipients of deceased-donor liver grafts preserved with NMP or sequential hypothermic-normothermic machine perfusion (SHNMP) will be randomized in a 1:1 ratio to either standard graft implantation with recooling using cold preservation solution (control group) or implantation without recooling using a room-temperature 5% albumin flush immediately before reperfusion (intervention group).
The primary objective is to compare the incidence of Early Allograft Dysfunction (EAD), defined according to the Olthoff criteria, between the two treatment groups. Secondary objectives include evaluation of histopathological ischemia-reperfusion injury using the Suzuki score, vascular and biliary complications, primary non-function, post-reperfusion syndrome, patient and graft survival, length of intensive care unit and hospital stay, perioperative transfusion requirements, and safety outcomes. A total of 170 participants will be enrolled across multiple Italian liver transplant centers and followed for 90 days after transplantation.

|
实验性的:No Recooling
No Recooling Before Liver Implantation
|
After completion of normothermic machine perfusion, the liver graft is flushed with 5% albumin solution at room temperature (20-25°C) and implanted without recooling.
The graft remains at near-normothermic temperature throughout the transition from ex vivo perfusion to in situ implantation, avoiding the conventional cold preservation flush before reperfusion.
|
|
有源比较器:Traditional Recooling
Traditional Recooling Before Liver Implantation
|
After completion of normothermic machine perfusion, the liver graft undergoes the standard preservation procedure consisting of a cold preservation solution flush before implantation, resulting in graft recooling prior to reperfusion.
The remainder of the transplantation procedure follows standard clinical practice.
