Spots Global Cancer Trial Database for Dexmedetomidine-esketamine Combined Nasal Administration and Perioperative Sleep Quality

Study Description

Brief 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.

Detailed Description: Normal sleep is important for maintaining both physical and mental health. Patients who are scheduled for breast cancer surgery often have sleep disturbances during the perioperative period. Patients with persistent sleep disturbances have increased sensitivity to pain and are at increased risk of developing chronic postsurgical pain. 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 improves sleep quality. Nasal administration of dexmedetomidine has been used in children as a premedication and in adults to reduce emergence agitation. 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. Nasal administration of esketamine has been used in children to relieve pain and in adults for treatment-resistant depression. This randomized trial is designed to test the hypothesis that combined nasal administration of low-dose dexmedetomidine-esketamine at night can improve perioperative sleep quality in patients scheduled for breast cancer surgery.
