- Abstract: Objective To analyze the effect of different doses of esketamine and different time in-tervals on reducing propofol injection pain(PIP)before intravenous propofol using factorial design.Methods A total of 360 elective general anesthesia surgical patients,167 males and 193 females,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ-Ⅲ were selected.Randomized numerical table method was used to divide the patients into three groups:esketamine 0.05 mg/kg(group A),esketamine 0.075 mg/kg(group B),and esketamine 0.1 mg/kg(group C),120 cases in each group.Each group was further randomly divided into 3 subgroups with 40 cases in each.Groups A1,A2,and A3 received intrave-nous propofol after induction of anesthesia with intravenous esketamine 0.05 mg/kg at intervals of 30 sec-onds,45 seconds,and 1 minute respectively.Groups B1,B2,and B3 received intravenous propofol after induction of anesthesia with intravenous esketamine 0.075 mg/kg at intervals of 30 seconds,45 seconds,and 1 minute respectively.Groups C1,C2,and C3 received intravenous propofol after induction of anesthe-sia with intravenous esketamine 0.1 mg/kg at intervals of 30 seconds,45 seconds,and 1 minute respective-ly.The McCririck scale was used to evaluate the occurrence of PIP.The induced dose of propofol,postoper-ative nausea and vomiting,respiratory amnesia,irritability,confusion,depressed and other adverse reactions were recorded.Results Comparison of the use of different doses of esketamine or different time intervals on the reduction of PIP showed a statistically significant difference respectively(P＜0.05).There was an interaction between different doses of esketamine and different intervals(P＜0.05).There were no significant differences in propofol induction dose and adverse reactions such as,postoperative nausea and vomiting,respiratory amnesia,irritability,confusion,depressed in nine groups of patients.Conclusion Compared with esketamine 0.05 and 0.1 mg/kg and intervals of 30 seconds and 1 minute,the use of esket-amine 0.075 mg/kg and intervals of 45 seconds followed by intravenous propofol is effective in suppressing PIP without the occurrence of significant adverse effects.
