Although the negative impacts of colloid solutions with high molecular weight on renal functions, combination of lower molecular weight colloid varieties with crystalloid solutions and its use during intraoperative period have been subject to current research. Since the first liver transplantation, pre-or post-transplantation renal problems are still among the main causes of mortality and morbidity. The aim of the study was to evaluate the effects of fluid replacement solutions used intraoperatively on renal functions in elective living-donor liver transplantation.This study was approved by the Ethics Committee of Hospital and all patients were informed and gave written consent. Participants were patients scheduled for elective living-donor liver transplantation. Patients with normal renal function were randomly allocated to infusion with 6% HES 130/0.4 (HES Group) and 4% Gelofusine (GEL Group). Blood samples were obtained before induction of anesthesia (baseline), at the end of the operation, and postoperative days 1 and 4. Different eGFR formulas using creatinine (MDRD, CKD-EPI, and Cockraud Gault) were used to calculate estimated glomerular filtration rates.
