Abstract:
Objective To compare the effects of tracheal intubation (TI) and laryngeal mask (LM) during general anesthesia (GA) induction on the α 1-band of quantitative pharmaco-electroencephalography (QPEEG).Methods Fortypatients undergoing GA were randomly divided into two groups:group T included 20 patients who received TI and group L included 20 who received a LM.Parameters like heart rate (HR),mean arterial pressure (MAP),and QPEEG were recorded before anesthesia induction (T0),after induction (T1),and after intubating the cannula or LM (T2).Using power-spectrum analysis,we calculated the power percentage of the α 1-band of QPEEG.Results The HR,MAP,and power percentage of the α 1-band in most areas of the brain were lower at T1 than at T0 (P < 0.05) in both groups.Moreover,the HR,MAP,and α 1-band power percentage were higher at T2 than at T1 (P < 0.05) in group T,whereas they showed no significant change at T2 (P > 0.05) in group L.Conclusion TI is stronger than LM for stimulating the circulatory system.Moreover,TI may cause an increase in the power percentage of the α 1-band of QPEEG.This finding suggests that the α1-band power percentage of QPEEG can be an effective means of monitoring stimulation.
