Brief Summary

Bladder cancer is one of the most common genitourinary cancers. Transurethral resection of bladder tumor (TURBT) is the standard therapy for nonmuscle invasive bladder cancer. However, patients after TURBT are at risk for recurrence and progression. Benzodiazepines are proved to inhibit proliferation of multiple types of cancer cells in vitro. Delirium is an acute onset and transient cerebral dysfunction and is associated with worse outcomes. Previous studies indicated that benzodiazepines increase incidence of postoperative delirium. Remimazolam is a new benzodiazepine with rapid onset and ultra-short activity. The aims of this study are to explore the impact of remimazolam for general anesthesia on emergency delirium and recurrence-free survival in patients undergoing bladder cancer surgery.
