NCT ID NCT07569614

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compared two sedative drugs—remimazolam and dexmedetomidine—to see which one better prevents postoperative delirium (sudden confusion) in patients aged 60 and older after thoracoscopic surgery. A total of 105 participants were randomly assigned to receive one of the two drugs or a placebo. The goal was to find a safer anesthesia option for older adults, who are at higher risk for delirium and related complications.
