Activation of GABAergic neurons in the GAD_(67)-GFP knock-in mouse brain during loss of consciousness induced by propofol

We try to determine the effective plasma concentration of propofol(EC_(P50)) by TCI for loss of consciousness(LOC) in 50% of elderly patients aged 60～69yr and 70～79yr, and the effective plasma concentration of reminfentanil(EC_(R50)) by TCI combini.

The aim of this study was to compare effects of different target controlled plasma concentrations of remifentanil on the effective plasma concentration of propofol by TCI for loss of consciousness(LOC) in 50% of elderly patients aged 60-80yr,and to determine the effective plasma concentration of propofol by TCI combining remifentanil to prevent response to tracheal intubtion(TI) in 50.
