Impact of Perioperative Dexmedetomidine and Esketamine on Postoperative Quality of Recovery in Patients Undergoing General Anesthesia and Surgery: A 2×2 Factorial Randomized Trial
In Brief
A Phase 4 clinical trial evaluating Dexmedetomidine, Esketamine, and 2 other interventions for General Anesthesia and 4 related conditions. Currently recruiting, targeting 316 participants across 1 site.
Detailed Summary
For patients after surgery, quality of recovery has significant impacts on the prognosis, quality of life, and rational allocation of medical resources. Dexmedetomidine and esketamine have each been used during the perioperative period and improved postoperative analgesia and subjective sleep quality. This 2x2 factorial trial is designed to explore the effects of dexmedetomidine, esketamine, and their combination on the quality of recovery in patients recovering from surgery under general anesthesia.

Timeline
Interventions
A loading dose of dexmedetomidine (0.2 ug/kg) is administered after anesthesia induction, followed by a continuous infusion of dexmedetomidineat a rate of 0.2 ug/kg/h until 30 minutes before the end of surgery. Self-controlled analgesia is established with dexmedetomidine 100 ug and sufentanil 100 ug, diluated with normal saline to 100 ml, and programmed to deliver 2-ml boluses with a lock-out interval of 10 minutes and a background infusion rate at 1 ml/h for a duration of 48 hours.
A loading dose of esketamine (0.1 mg/kg) is administered after anesthesia induction, followed by a continuous infusion of esketamineat a rate of 0.1 mg/kg/h until 30 minutes before the end of surgery. Self-controlled analgesia is established with esketamine 50 mg and sufentanil 100 ug, diluated with normal saline to 100 ml, and programmed to deliver 2-ml boluses with a lock-out interval of 10 minutes and a background infusion rate at 1 ml/h for a duration of 48 hours.

A loading dose of placebo (normal saline) is administered after anesthesia induction, followed by a continuous infusion of placebo at a rate same as above until 30 minutes before the end of surgery. Self-controlled analgesia is established with sufentanil 100 ug, diluated with normal saline to 100 ml, and programmed to deliver 2-ml boluses with a lock-out interval of 10 minutes and a background infusion rate at 1 ml/h for a duration of 48 hours.
