“method grown-up domestic rabbit 8, female and male do not arrest, after the domestic rabbit has the convulsion the ear reason intravenous injection thiopental sodium, applies QPEEG immediately, uses the power spectrum analytic method, around the analysis convulsion domestic rabbit intravenous injection thiopental sodium QPEEGδ, Theta, α1, α2, α3, Beta six frequency band changes. The result before compares for the medicine, Delta when frequency band power percentage 2min obvious markup (p<),20minLatter reduces normally. Theta when frequency band 1min-20min the power percentage reduces (p obviously .The conclusion thiopental sodium has obviously to gentleman's convulsion rather oppresses the anti-function, Theta the frequency band change is most remarkable, prompts may take when the convulsion when the brain wave monitor main observation target as well as the thiopental sodium anti-convulsion amount used target. after Beta the frequency band activity assumes suppresses first, the excited phenomenon, after extrapolating the use thiopental sodium, possibly “easy to melt” the effect to organism cerebral cortex production.”
