With the increased use of contrast agents, the incidence of contrast induced nephropathy has Contrast induced nephropathy has become the third most common cause of renal injury caused by the hospital , following renal hypoperfusion and renal toxicity. But its pathogenesis is not clear, and there is no specific treatment. Therefore, prevention is particularly important. Intravenous hydration is widely recognized as an effective method, but is not suitable for all the patients. More researches on the current drug prevention of contrast induced nephropathy provide possibility in individual prevention of contrast nephropathy.

The method of remote ischemic preconditioning is simple, noninvasive and effective, and should be the first method.
