Summary

This study looked at whether a newer anesthetic drug, remimazolam, causes less confusion after surgery in people aged 60 and older compared to a standard drug, propofol. The researchers measured how many patients experienced delirium (sudden confusion) within three days after their operation. The goal was to find a safer way to put elderly patients to sleep for surgery.
