Efficacy of Esketamine Combined With Different General Anesthetics on Quality of Postoperative Recovery

In this study, we planned to conduct a single-center, prospective, randomized, controlled, double-blind clinical trial to explore the effect of subanesthetic dose esketamine combined with different general anesthesia drugs on the postoperative recovery quality of patients undergoing painless gastrointestinal endoscopy combined with several commonly used intravenous general anesthesia drugs, aiming at gastroscopy combined with colonoscopy, a representative type of diagnosis and treatment of painless and comfortable anesthesia, and to provide more evidence-based medical evidence for clinical work.
