The Effect of Remote Ischemic Preconditioning on Myocardial Injury After Noncardiac Surgery

Remote ischemic preconditioning will consist of four cycles of 5-minute inflation of an blood pressure cuff on the upper arm to 200 mmHg followed by 5-minute deflation. RIPC will be performed twice, one at approximately 24 hours before anaesthesia and the other at approximately 1 hour before anaesthesia.

The identical looking cuff will be placed around the upper arm but not actually inflated for 40 minutes. The control device's components and external appearance are identical to that of the RIPC. However, as compared to the RIPC, the blood pressure cuff's line of inflation is disconnected such that the cuff cannot be inflated. Control treatment will be performed twice, one at approximately 24 hours before anaesthesia and the other at approximately 1 hour before anaesthesia.
