Relation Between PRST Score, Skin Conductance and BIS
Relation Between PRST Score, Skin Conductance and BIS
Determine the relation between PRST (pressure, rate, sweating, tears) score, skin conductance
 (SC) and Bispectral index (BIS) values during anesthesia
Probability of >0 points in the PRST as a function of BIS and number of fluctuations in mean
 skin conductance (NFSC) will be recorded during the anesthesia.
