Effect of Stellate Ganglion Block on Cardiac and Renal Function After Cardiopulmonary Bypass Cardiac Surgery

• Status: Recruiting
• Trial end date: 2024-07-01
• Target enrollment: 0
• Participant gender: All

Summary

The incidence of acute kidney injury after cardiopulmonary bypass cardiac surgery is high, which increases postoperative mortality and is not conducive to the prognosis of patients. Stellate ganglion blocks increase renal blood flow, reduce inflammation and stress, and protect the heart muscle. In this study, stellate ganglion block was used to promote rapid recovery of heart and kidney function after cardiopulmonary bypass cardiac surgery.

• Phase: N/A
• Accepts Healthy Volunteers?: No
