Effects of Low-dose Dexmedetomidine-esketamine Combined Nasal Administration at Night on Perioperative Sleep Quality in Breast Cancer Patients: a Randomized, Double-blind, Placebo-controlled Trial

Peking University First Hospital·interventional·Posted Feb 16, 2023·Updated Jul 31, 2025

In Brief

A Phase 4 clinical trial evaluating Dexmedetomidine, Esketamine, and 1 other intervention for Breast Cancer and 4 related conditions. Completed, enrolled 180 participants across 1 site.

Detailed Summary

Breast cancer patients often have sleep disturbances during the perioperative period. Dexmedetomidine is a highly selective alpha 2-adrenoceptor agonist with sedative, anxiolytic, and analgesic effects. Previous studies showed that night-time low-dose dexmedetomidine infusion improved sleep quality. Esketamine is a N-methyl-D-aspartic acid receptor antagonist and has been used as an anesthetic and analgesic. Recent studies showed that low-dose esketamine has anti-depressive and sleep-promoting effects. The investigators suppose that low-dose dexmedetomidine-esketamine combined nasal administration at night can improve perioperative sleep quality in patients scheduled for breast cancer surgery.
