Abstract:
Objective: To study the effects ot intravenous 1% procaine on cortex. Method: Ten patients,aged 29-59 years,for elective surgical operations,were observed the changes of spectral edge frequency(SEF), medium power frequency (MPF)and ? rate(?R)on power spectral analysis and bispectral index(Bl)on bispectral analysis during intravenous propofol 4 mg?kg~(-1)? h~(-1) purely for 15 min,intravenous combination of 1% procaine 1mg?kg~(-1)?min~(-1) and propofol for 30 min, then intravenous propofol 4mg?kg~(-1)?h~(-1)purely for 15min. Result: SEF,MPF and BI values during combination stage were lower significantly (15.46?1.87Hz, 7.21?2.01Hz, 68.77?7.99 respectively)than the values during other two stages(stage 1 and stage 2 were 21.36?2.79Hz,11.55?2.62Hz,85.6?8.84 and 20.59?3.10Hz, 9.5?3.44Hz, 84.97?8.71 respectively, P
