Data are expressed as mean (SD)
BIS bispectral index, BP blood pressure, SD standard deviation
*p < 0.05; significant difference from baseline (difference within the group)
**p < 0.05; significant difference between the propofol + saline and propofol + remifentanil groups by ANOVA with repeated measurements
