Effect of RIPC on the Prevention of POD in Patients Undergoing Cardiac Surgery

Not Applicable

• Conditions: Postoperative Delirium; Cardiac Surgery

• Registration Number: NCT05434455
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

Postoperative delirium (POD) is one of the most frequent neurological complications in elderly patients and is closely associated with longer ICU stay and hospitalization, deterioration of long-term neurocognitive function, and increased mortality. The incidence of POD is significantly higher in elderly patients undergoing cardiac surgery than in other populations. Therefore, the prevention of POD is an important clinical problem to be solved urgently. In this study, we intend to observe the effect of RIPC on the prevention and treatment of POD in patients undergoing cardiac surgery through a prospective randomized controlled trial.
