Abstract:
Objective To evaluate the effect of remifentanil pretreatment on myoclonus after etomidate injection.Methods Sixty patients undergoing scheduled for intestinal endoscopy under general anesthesia were divided into remifentanil group and control group by random digits table method with 30 cases each.Before 0.3 mg/kg etomidate was given,the patients in remifentanil group and control group were pretreated with remifentanil 0.5 μ g/kg or amount of 0.9％ sodium chloride.Myoclonus was observed and recorded.Nausea,pruritis and apnea were observed after procedures.Results The incidence of myoclonus was 73.3％(22/30) in control group,mild in 11 cases,moderate in 10 cases and severe in 1 case.The incidence of myoclonus was 6.7％(2/30) in remifentanil group and mild in 2 cases.There was significant difference in the incidence of myoclonus between two groups (P ＜ 0.01).In control group,the ratio of myoclonus was 14/16 in males and 8/14 in females.In remifentanil group,male and female each had 1 case of myoclonus.There was no nausea,pruritis and apnea in remifentanil group.Conclusion Pretreatment with 0.5 μ g/kg remifentanil reduces myoclonus after etomidate injection,male patients are more associated with the incidence of myoclonus than female patients.
