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.

Conditions

  • Adults
  • Major Noncardiac Surgery
  • Dexmedetomidine
  • Esketamine
  • Postoperative Sleep Disturbances

Interventions

DRUG

Dexmedetomidine-esketamine combination

Dexmedetomidine 0.4 μg/kg and esketamine 0.2 mg/kg is infused over 10 minutes before anesthesia induction. Dexmedetomidine 0.20 μg/kg/h and esketamine 0.10 mg/kg/h is then infused until 60 minutes before the expected end of surgery. Patient-controlled intravenous analgesia is established with 100 μg dexmedetomidine, 50 mg esketamine, and 100 μg sufentanil, diluted to 100 mL with normal saline, and programmed to deliver 2-mL boluses with a lock-out interval of 8 minutes and background infusion rate at 1 mL/h for up to 72 hours after surgery.

DRUG

Placebo

Placebo (normal saline) is administered in the same rate and volume as that in the dexmedetomidine-esketamine group. Patient-controlled intravenous analgesia is established with 100 μg sufentanil, diluted to 100 mL with normal saline, and programmed to deliver 2-mL boluses with a lock-out interval of 8 minutes and background infusion rate at 1 mL/h for up to 72 hours after surgery.
