Brief Summary

Sedation drugs that are commonly used in ICU in treatment of ARDS, includes propofol, midazolam and dexmedetomidine . Among these, both dexmedetomidine and propofol have been reported to be used together with midazolam in ICU and the combination of propofol and midazolam is most commonly used, but things follow include a high incidence rate of delirium, But the combination of midazolam and dexmedetomidine may have complementary advantages and could have be a better choice for sedation. In this study, we attempted to observe the effects of two different drug regimens on delirium incidence rates in severe ARDS patients' : midazolam and propofol vs propofol and dexmedetomidine .

Outcome Measures

Primary Outcomes (2)

  • Incidence rates and duration of delirium

    Incidence rates and duration of delirium within 14 days after initiation of sedation with dexmedetomidine or propofol

    up to 15 days

  • Sedation interruption

    Eye opening according to the voice orders, eye tracking, clenching fist and nodding are involved in assessment, patients could do 3 of those or more is deemed as conscious and taken in delirium assessment.

    up to 5 days

Secondary Outcomes (8)

  • Sedation therapy effect

    up to 7 days

  • Hospitalized days in ICU

    up to 15 days

  • Death rates

    28 days

  • Incidence rate of patients self-extubation

    up to 7 days

  • Injection speed, total dose and injection of sedatives in different groups.

    7 days

  • +3 more secondary outcomes

Study Arms (2)

Dexmedetomidine,midazolam

EXPERIMENTAL

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

Propofol,midazolam

ACTIVE COMPARATOR

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.

Drug: Propofol,midazolam

Interventions

Dexmedetomidine,midazolam
Propofol,midazolam
