Brief summary
Ischemia-reperfusion (IR) injury during liver transplantation is one of the major causes of mortality and morbidity associated with transplantation. Remote organ ischemic preconditioning (RIPC) is one of the most investigated practices to reduce IR injury. In this study, for the first time in the clinic, the effect of RIPC will be evaluated via both systemic inflammation parameters and also parameters showing glycocalyx integrity, on living-donor liver recipients.
Interventions
An orthopedic tourniquet was tied to the right lower extremities of the patients in RIPC arm, and tourniquet application was performed before the anhepatic phase in 3 periods of 3 minutes with an interval of 3 minutes.
