Brief Summary:
The purpose of this study is to study the effect of remote ischemic preconditioning on acute kidney injury in patients undergoing heart valve replacement surgery with cardiopulmonary bypass.

Condition or disease Intervention/treatment Phase
Heart Valve Disease Procedure: Automated cuff-inflator Not Applicable

Detailed Description:
Hypothesis : RIPC using tourniquet might be a simple technique with the benefit to provide renal protection without disturbing operating procedure and prolongation of total operating time.

Arm Intervention/treatment
Experimental: Automated cuff-inflator Procedure: Automated cuff-inflator
RIPC protocol consisted of three 10-min cycles of lower limb ischemia at an inflation pressure of 250 mmHg induced by an automated cuff-inflator placed on the upper leg with an intervening 10 min of reperfusion during which the cuff was deflated.
