Psychomotor and driving skills after propofol sedation were similar to the baseline results , while in the midazolam/pethidine group , patients showed significantly more lane deviations ( 1.1 + / - 0.9 vs. 1.6 + / - 0.9 ) , time over the speed limit ( 0.3 + / - 0.83 vs. 0.6 + / - 0.88 ) , missed stoplights more often ( 0.05 + / - 0.31 vs. 0.11 + / - 0.35 ) , and had slower reaction times for unexpected events ( 1.11 + / - 0.46 s vs. 1.39 + / - 0.44 s ) ( P < 0.01 ) .
