Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

During cardiac surgery with cardiopulmonary bypass , pulmonary dysfunction remains to be a problem complicating the postoperative course of the patients.Remote ischemic preconditioning(RIPC) with transient upper limb ischemia/reperfusion is a novel, simple, cost-free,non-pharmacological and non-invasive strategy.Recent several trials suggested that RIPC could provide pulmonary protection by reducing serum biomarkers,however,whether the RIPC can improve the clinical outcomes in patients undergoing on-pump cardiac surgery,is still uncertain.

The study hypothesis is: remote ischemic preconditioning will provide lung-protective effect and improve clinical outcomes in patients undergoing cardic surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Remote ischemic preconditioning (RIPC) protocol will be induced during anesthesia by 3 cycles of 5-min upper limb ischemia and 5-min reperfusion using a blood pressure cuff inflated to a pressure 200mmHg
