Effects of Mannitol on Delayed Graft Function After Cadaveric Renal Transplantation

November 5, 2018 updated by: Samir Sljivic, Medical University of Vienna

In this study we want to evaluate the effect of mannitol on postoperative renal biomarkers in patient receiving cadaveric renal transplantation. Furthermore we want to evaluate the effect of mannitol on perioperative redox status in patients receiving renal transplantation using the oxidation-reduction potentials assessed with the RedoxSYS®system.

We are planning to perform a double-blind randomized controlled trial. In the study, mannitol 20% with a dose of 1g / kg / BW (5 ml / kg / BW) will be compared to placebo with NaCl 0.9% in the dose of 5 ml / kg / BW. Patients will be randomized to receive either the mannitol or NaCl. The follow-up of the study is 24 hours. The following biomarkers will be determined befor induction of anesthesia and 24 hours after administration of study medication: CCL2, CHI3LI, GH, HGF, MMP1, MMP8, Tie2, TNF-R1, VCAM-1, KIM-1, Cystatin C, FGF23, IGFB7, NGAL and IL 18.

Furthermore we want to perform sORP and cORP before induction of anesthesia, just before bolus of mannitol, 5 min after bolus of mannitol and after operation in anesthetic recovery room.

Data will be collected, compared and published at the end of the study. It is planned to include a total of 34 patients in the study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Mannitol 20%
Mannitol 1g/ kg BW
Drug: Mannitol
In the study, mannitol 20% with a dose of 1g / kg / BW (5 ml / kg / BW) will be compared to placebo with NaCl 0.9% in the dose of 5 ml / kg / BW. The study medication will be administered immediately before organ reperfusion. The follow-up of the study is 24 hours.
Placebo Comparator: Nacl 0.9%
NaCl 0.9% 5ml/ kg BW
Drug: Mannitol
In the study, mannitol 20% with a dose of 1g / kg / BW (5 ml / kg / BW) will be compared to placebo with NaCl 0.9% in the dose of 5 ml / kg / BW. The study medication will be administered immediately before organ reperfusion. The follow-up of the study is 24 hours.
