Effects of Esketamine on Oxygenation and Quality of Recovery in Patients Undergoing Thoracoscopic Surgery

A total of 126 patients undergoing thoracoscopic surgery under elective general anesthesia were randomly divided into three groups: normal saline group (group C), dexmedetomidine group (group D), eschloroacetone group (group E) and dexmedetomidine group (group D), with 42 cases in each group. Group C was continuously injected with the same amount of normal saline, group D was given dextrometin 1 ug/kg load 10min before surgery, and maintained at 0.4 ug/kg\*h after intubation until 30min before the end of surgery. Group E was given esketamine 0.2 mg/kg 10min before surgery, and maintained at 0.15 mg/kg\*h after intubation until 30min before surgery. Other anesthetic induction and maintenance drugs were consistent among the three groups.

group D was given Dexmedetomidine 1 ug/kg load 10min before surgery, and maintained at 0.4 ug/kg\*h after intubation until 30min before the end of surgery.

Group C was continuously injected with the same amount of normal saline,
