Brief Summary

Sleep disturbances are common early after major surgery, and are associated with delayed recovery. A previous study showed that dexmedetomidine-esketamine combination as a supplement to patient-controlled intravenous analgesia improved postoperative analgesia and subjective sleep quality in patients after scoliosis correction surgery. The purpose of this trial is to test the hypothesis that dexmedetomidine-esketamine combination used as a supplement during general anesthesia and postoperative intravenous analgesia may reduce sleep disturbances in adult after major noncardiac surgery.

Eligibility Criteria

Inclusion Criteria: 1. Aged ≥18 years. 2. Scheduled for major noncardiac surgery (≥60 minutes) under general anesthesia with an expected end of surgery no later than 18:00 pm. 3. Required patient-controlled intravenous analgesia after surgery. Exclusion Criteria: 1. Emergency surgery, transurethral surgery, organ transplantation. 2. Pregnant or lactating women. 3. Patients who need hypnotics for sleep disturbance or antidepressants for depression prior to surgery. 4. History of schizophrenia, epilepsy, Parkinson's disease, or myasthenia gravis. 5. Inability to communicate due to coma, severe dementia, or speech disorders, endured hypoxic encephalopathy or traumatic brain injury, or after neurosurgery. 6. Comorbid with hyperthyroidism and pheochromocytoma. 7. Preoperative left ventricular ejection fraction \<30%, sick sinus syndrome, severe sinus bradycardia (heart rate \<50 beats/min), atrioventricular block of degree II or higher without pacemaker implantation, or systolic blood pressure below 90 mmHg despite use of vasopressors. 8. Diagnosed as sleep apnea, or judged to be at high risk of moderate-to-severe sleep apnea as assessed by STOP-Bang. 9. Severe hepatic dysfunction (Child-Pugh class C), severe renal dysfunction (on dialysis), or ASA classification ≥IV. 10. Hypersensitive to dexmedetomidine and/or esketamine. 11. Other conditions that are deemed unsuitable for study participation.
