Ratio of propofol dosage to body weight when loss of eyelash reflex and IOC60 (A). Onset time of cisatracurium (B). The onset time of cisatracurium was defined as the time from the end of cisatracurium injection to 95% of T1 decay. The ratio of propofol dosage to body weight when loss of eyelash reflex and IOC60 were showed as mean ± SD, and were analyzed with Welch test followed by Games-Howell post hoc comparison. Onset time of cisatracurium were showed as mean ± SD, and were analyzed with One-Way analysis of variance(ANOVA) followed by Bonferroni post hoc comparison. *P < 0.05 vs. Group C. †P < 0.05 vs. Group K0.1. ‡P < 0.05 vs. Group K0.3. Abbreviations: Group C (control): injected with normal saline. Group K0.1: injected with 0.1 mg/kg esketamine. Group K0.3: injected with 0.3 mg/kg esketamine. Group K0.5: injected with 0.5 mg/kg esketamine.
