Arms of the Study

Arm 2
Arm Type
No Intervention
Experimental
Arm Label
Non remote ischemic conditionin(non-rIC)
Remote ischemic conditioning (rIC)
Arm Description
Patients receiving kidney transplantation from a deceased donor. This group does not receive remote ischemic conditioning, but has a tourniquet on the leg (not inflated).
Patients receiving kidney transplantation from a deceased donor. This group receives remote ischemic conditioning by inflating a tourniquet on the leg during surgery, before reperfusion of the kidney.
Outcomes
Primary Outcome Measures
Time to a 50% drop in baseline plasma-creatinine
Plasma-creatinine changes posttransplant will be described using an exponential/logistic/linear model depending on the individual patient data. All plasma-creatinine values 30 days posttransplant, or in case of temporary posttransplant dialysis 30 days after the last performed dialysis, will be used, measured minimum twice daily initially. Baseline plasma-creatinine is measured approximately 1 hour prior to reperfusion of the kidney. Time to a 50% drop in baseline plasma-creatinine will be estimated.
Secondary Outcome Measures
Need for dialysis
GFR after 1 year
GFR measurement by Cr-EDTA.

5. Study Description
Brief Summary
The purpose of this study is to determine whether remote ischemic conditioning can improve the outcome after renal transplantation with deceased donor. Remote ischemic conditioning is performed on the patient receiving a kidney from a deceased donor. Remote ischemic conditioning is done during the operation by inflating a tourniquet on the patients leg before opening the blood circulation to the kidney. The study focus on both the immediate kidney function after the transplantation, but also on the extended kidney function one year after the transplantation.

Intervention Type
Other
Intervention Name(s)
Remote ischemic conditioning
Other Intervention Name(s)
Remote ischemic preconditioning, Ischemic conditioning
Intervention Description
Patients receiving kidney transplantation from a deceased donor. Remote ischemic conditioning (rIC) is done by inflating a tourniquet (250mmHg) on the patients leg before reperfusion of the kidney. The tourniquet stays on the leg on the opposite site of were the kidney is placed. rIC is done 4 x 5 min with 5 min intervals between with free blood flow.
