Overview
Brief Summary
Pulmonary dysfunction after cardiac surgery with CPB remains to be a problem complicating the postoperative course of the patients. The investigators hypothesized that RIPCcom, combined intervention of remote ischemic preconditioning and remote ischemic postconditioning, would confer beneficial influence on inflammatory response and resultant postoperative pulmonary dysfunction after CPB in patients undergoing complex valvular heart surgery who are at increased risk of postoperative pulmonary dysfunction.The aim of this study was to evaluate the lung-protective effect of combined remote ischemic pre- and post-conditioning in patients undergoing complex valvular heart surgery.
