Experimental: Dexmedetomidine,midazolam
Slow injection of 2mg midazolam every minute and watching patients' reaction until attaining the target level of sedation;midazolam was maintained at 0.02~0.1mg/kg/h, for 24 hours.Dexmedetomidine will be added at 0.2~1.4μg/kg/h to maintain sedation.If target sedation level (RASS score) cannot be reached in maximum dose of dexmedetomidine, continuous intravenous infusion of midazolam could be used at 0.02~0.1mg/kg/h, until the target level is reached.

Drug: Dexmedetomidine,midazolam |
Active Comparator: Propofol,midazolam
Slow injection of 2mg midazolam every minute and watching patients' reaction until attaining the target level of sedation;midazolam was maintained at 0.02~0.1mg/kg/h, for 24 hours.Propofol will be added at 0.3~4mg/kg/h to maintain sedation.If target sedation level (RASS score) cannot be reached in maximum dose of propofol, continuous intravenous infusion of midazolam could be used at 0.02~0.1mg/kg/h, until the target level is reached.
