Impact of Dexmedetomidine Supplemented Analgesia on Incidence of Delirium in Elderly Patients After Cancer Surgery: a Multicenter Randomized Controlled Trial

Peking University First Hospital·interventional·Posted Jan 6, 2017·Updated Jan 8, 2026

In Brief

A clinical study evaluating Dexmedetomidine supplemented morphine analgesia and Morphine analgesia for Elderly and 5 related conditions. Completed, enrolled 1,500 participants across 12 sites.

Detailed Summary

Delirium is a frequently occurred cerebral complication in elderly patients after surgery, and its occurrence is associated with worse outcomes. Sleep disturbances is considered to be one of the most important risk factors of postoperative delirium. Previous studies showed that, for elderly patients admitted to the ICU after surgery, low-dose dexmedetomidine infusion improved the quality of sleep and decreased the incidence of delirium. The investigators hypothesize that, for elderly patients after cancer surgery, dexmedetomidine supplemented analgesia can also decrease the incidence of delirium, possibly by improving sleep quality. The purpose of this multicenter, randomized controlled trial is to investigate the impact of dexmedetomidine supplemented analgesia on the incidence of delirium in elderly patients after cancer surgery.

Interventions

Dexmedetomidine supplemented morphine analgesiadrug

Patients in this group will receive patient-controlled intravenous analgesia for 3 days after surgery. The formula is a mixture of dexmedetomidine (1.25 ug/ml) and morphine (0.5 mg/ml), diluted with normal saline to 160 ml. 5-HT3 receptor antagonist is added when necessary. The analgesic pump is set to administer a background infusion at a rate of 1 ml/h, with a bolus dose of 2 ml each time and a lockout time from 6 to 8 minutes according to patients' condition.
