Anesthesia Maintenance With Target-controlled Infusion of Propofol and Remifentanil at Fixed Ratio on Neurocognitive Recovery in Older Patients After Surgery: a Randomized Trial

Peking University First Hospital·interventional·Posted Mar 18, 2026·Updated Mar 18, 2026

In Brief

A Phase 4 clinical trial evaluating Light anesthesia and Deep anesthesia for Elderly and 4 related conditions. Not yet recruiting, targeting 200 participants across 1 site.

Detailed Summary

The impact of anesthesia depths on early postoperative neurocognitive complications after total intravenous anesthesia (TIVA) remains controversial. In some studies investigating TIVA, anesthesiologists mainly achieve the target depth of anesthesia by adjusting the dose of propofol, whereas the doses of opioids remains comparable between different anesthetic depth groups, possibly resulting inadequate analgesia. This study is aimed to investigate the impact of different anesthesia depths maintained by target-controlled infusion of propofol and remifentanil at a fixed ratio on the incidence of early postoperative neurocognitive complications in older patients undergoing noncardiac surgery.
