About this study
Official title: Low-dose Neuroleptanalgesia Reduce the Occurrences of Postoperative Delirium in Elderly Patients Undergoing Non-cardiac Major Surgery : a Randomized Controlled Trial
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?
Incidences of POD after general anesthesia in elderly patients undergoing non-cardiac major surgery (time frame: Up to 7 days after surgery（or leaving hospital）). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2021; AzTrials last refreshed its copy on 7 Nov 2026.
