Effect of hydromorphone pretreatment on myoclonus induced by etomidate

Objective To observe the effect of hydromorphone pretreatment on myoclonus induced by etomidate general anesthesia.Methods A total of 180 patients undergoing elective surgery under general anesthesia from December 2017 to December 2018,ASAⅠtoⅡ,aged 18 to 60 years old,were divided into 3 groups by stratified randomization,with 60 cases in each group.GroupⅠreceived intravenous injection of hydromorphone 5μg/kg,groupⅡreceived intravenous injection of sufentanil 0.1μg/kg,and groupⅢinjected the same volume of 0.9%sodium chloride solution intravenously.Observe and record whether there is respiratory depression,skin itching,and nausea.Vomiting,coughing and other adverse reactions.Etomidate 0.3 mg/kg was intravenously injected 5 minutes later,and the degree and incidence of myoclonus were observed and recorded in the 3 groups.Two minutes later,midazolam was given 0.05 mg/kg,groupsⅠandⅡwere given sufentanil 0.3μg/kg,groupⅢwas given sufentanil 0.4μg/kg and cis-atracuramide 0.15 mg/kg Line tracheal intubation.Results 2 patients in groupⅠhad mild myoclonus,4 patients in groupⅡhad mild myoclonus and 1 had moderate myoclonus,and 32 patients in groupⅢhad myoclonus,of which 12 had mild myoclonus,13 cases were moderate,7 cases were severe.There were no adverse reactions such as respiratory depression,coughing,skin itching,nausea and vomiting in the three groups of patients during pretreatment.Conclusion Pre-injection of 5μg/kg hydromorphone can significantly reduce the incidence and degree of myoclonus caused by etomidate,and there is no adverse reactions such as respiratory depression,nausea,vomiting,and skin itching.
