ABSTRACT
Objective: To investigate the effects of divided-doses mivacurium on histamine releasing and hemodynamics. Method: Forty-two patients were randomly divided into seven groups (n=6, each group). The total dose of 3?ED_(95)(0.25mg/kg)mivacurium for intubation was injected intravenously in single-dose in group I, or in divided-doses of 0.05+0.2mg/kg, 0.10+0.15mg/kg, 0.125+0.125mg/kg, 0.15+0.1mg/kg, and 0.2+0.05mg/kg in group Ⅱ, Ⅲ,Ⅳ, Ⅴ and Ⅵ respectively, and 0.6mg/kg of atracurium bolus in group Ⅶ, The plasma histamine concentration and systolic blood pressure(SP), diastolic blood pressure(DP) and heart rate(HR) were determined before and 3, 5, 10, and 15 min after injection of mivacurium or atracurium. Result: The plasma histamine concentration and changes of SP, DP, HR were decreased in group Ⅳ compared with those in other groups. Conclusion: The divided dose of 3?ED_(95) mivacurium for intubation may reduce histamine release and changes in hemodynamics.
