Effect of Ciprofol Injection on Postoperative Cognitive Function

25. juni 2026 oppdatert av: Guangyou Duan, The Second Affiliated Hospital of Chongqing Medical University

A Controlled Study on the Impact of Ciprofol Injection on Postoperative Cognitive Function and Its Mechanism

This study aims to explore the effect of ciprofol on the postoperative cognitive function of inpatients undergoing gastrointestinal endoscopy examination, to compare the anesthetic effects and differences in adverse reactions of propofol and ciprofol in gastrointestinal endoscopy , to compare the incidence of postoperative cognitive decline in patients undergoing gastrointestinal endoscopy examination between propofol and coprofol, and to optimize the anesthesia medication regimen for patients undergoing gastrointestinal endoscopy examination.
