Abstract:
Objective To compare the effects of different doses of sufentanil on theα1?band of quantitative pharmaco?electroencephalography (QPEEG)during the induction of general anesthesia by tracheal intubation(TI). Methods Forty selected patients under general anesthesia were randomly divided into two groups,with 20 patients per group. Patients in group Ⅰ were administered 0.2μg/kg sufentanil,whereas patients in group Ⅱ were administered 0.3μg/kg sufentanil. Subsequently,the patients were administered 2 mg/kg propofol and 0.15 mg/kg cisatracurium. HR,MAP,and QPEEG were recorded before induction(T0),after induction(T1),and after insertion of the cannula(T2). Using the method of power spectrum analysis,theα1?band power percentage of QPEEG was calculated. Results In comparison with T0,the values of HR,MAP,andα1?band power percentage in most areas of the brain were both decreased at T1(P<0.05). Furthermore,in comparison with T1,the parameters were increased in group Ⅰ at T2(P<0.05),but no significant changes were observed in group Ⅱ (P>0.05). Conclusion The administration of 0.3μg/kg sufentanil during anesthesia induction can effectively depress the cardiovascular response to TI and stabilize theα1?band power per?centage. This suggests that theα1?band power percentage of QPEEG can be an effective means to monitor the depth of sedation.
