The following data were collected: length of stay in the ICU, incidence of readmission to the ICU, readmission cause, serum creatinine peak level, incidence of renal failure assessed by the RIFLE (risk, injury, failure, loss, endstage of kidney disease) criteria, incidence of RRT, incidence of sepsis, incidence of pulmonary failure (acute respiratory distress syndrome (ARDS), pneumonia with consecutive reintubations), ventilation days, serum peak values of bilirubin, alkaline phosphatase, alanine aminotransferase (ALT) and aspartate aminotransferase (AST); incidence of primary graft nonfunction and retransplantation, incidence of rejection on the ICU and reoperations during the ICU stay, and the incidence of acute coronary syndrome. In the case of four primary graft nonfunctions in the ICU with a following four consecutive emergency retransplantations, we considered those four retransplantations as ICU complications and analyzed these patients as four ICU cases. Furthermore, we considered three electively listed retransplantations as three additional cases and therefore calculated the ICU parameters from 147 transplantation cases out of 144 patients. The graft specific parameters, that is peaks of bilirubin, alkaline phosphatase, ALT and AST, were analyzed from all 151 transplanted grafts.
