Effect of Remote Ischemic Preconditioning on the Incidence of Contrast Induced Nephropathy in Patients Undergoing EVAR

In the 12 hours prior to surgery, the principal investigator performed the remote ischemic preconditioning (RIPC) following the protocol: 4 cycles of inflation/deflation of a pneumatic arterial tourniquet on the non-dominant upper extremity. Considering inflated a pressure of 50mmHg above systolic blood pressure for 5 minutes, followed by 5 minutes of deflation. Patients included in the preconditioning group were randomized at a rate of 1:1 consecutively.
