Heart Valve Disease
Conditions
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.
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.
Interventions
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.
