Outcome Measures

Primary Outcomes (1)

  • Renal function

    within the first 48h after cardiac surgery

Secondary Outcomes (4)

  • concentration of troponin I (cTnI)

    within 48h after cardiac surgery

  • Myocardial enzyme

    within 48h after cardiac surgery

  • Cystatin C

    within 48h after cardiac surgery

  • High-sensitivity c-reactive protein(HS-CRP)

    within 48h after cardiac surgery

Study Arms (1)

Manual Tourniquet

EXPERIMENTAL
Device: Remote ischemic postconditioning

Interventions

the treatment group consisted of three 4-minute cycles left lower limb ischemia,induced by inflating a blood pressure cuff on the lower limb to 600 mmHg with an intervening 4 minutes of reperfusion ,during which time the cuff was deflate;the control group consisted of placing an uninflated cuff on the left lower limb for 24 minutes.The postconditioning protocol was applied after the aortic cross-clamping.

Also known as: Manual Tourniquet YZ-01
