Brief summary

Postoperative delirium(POD)is a common complication that can directly affect important clinical outcomes, and exert an enormous burden on patients, their families, hospitals, and public resources. In order to evaluate whether an intraoperative administration of low-dose neuroleptanalgesia reduces postoperative delirium, droperidol 1.25 mg and fentanyl 0.025 mg or normal saline is used by intravenous injection 30 minutes before the end of the operation, in elderly patients with non-cardiac major surgery under general anesthesia. The efficiency and safety of neuroleptanalgesia on the incidence of POD would be evaluated in elderly patients.

Interventions

DRUGlow-dose neuroleptanalgesia

Droperidol 1.25 mg and fentanyl 0.025 mg (diluted with normal saline up to 5ml) is to be administrated intravenously 30 minutes before the end of the procedure.

DRUGPlacebo

The same volume of normal saline is to be administrated intravenously 30 minutes before the end of the procedure.
