NCT05160987

Brief Summary

In this parallel, multicenter, single-blind randomized controlled trial, mechanical ventilated patients will be randomly assigned to two groups. One receives remimazolam to achieve sedation goals, while the other receives Midazolam. The primary outcome is the effect of remimazolam on duration of mechanical ventilated of critical patients compared to midazolam.

Outcome Measures

Primary Outcomes (1)

  • Duration of mechanical ventilation

    Weaning success is typically regarded as consecutive ventilator-free over 24h following liberation from a ventilator. The duration of mechanical ventilation is from the enrollment time to the weaning time. The study and observation would be stopped due to difficult ventilator weaning, which features weaning failure repeatedly for 3 weeks.

    From the date of enrollment until the date of successful ventilator withdrawal, assessed up to 28 days

Secondary Outcomes (6)

  • Duration of endotracheal intubation

    From the date of enrollment until the date of pulling out the endotracheal tube, assessed up to 28 days

  • Completion rate of sedation goal

    From the date of enrollment until the date of successful ventilator withdrawal, assessed up to 28 days

  • Remediation is defined as requiring combination with other sedations

    From the date of enrollment until the date of successful ventilator withdrawal, assessed up to 28 days

  • Length of stay in ICU and total length of stay

    From the date of admission in ICU until the date of transfer from ICU

  • Anterograde amnesia

    From the date of enrollment until the date of successful ventilator withdrawal

  • +1 more secondary outcomes

Study Arms (2)

Remimazolam Group

EXPERIMENTAL

The patients are administered with sedation of remimazolam and analgesia of remifentanil on the basis of routine treatment. If the patient does not receive sedative drug before enrollment, patient would be administered with a bolus of remimazolam with 0.1-0.3mg/kg intravenously in 1 minute for the first time. And maintenance dose is 0.25-0.1mg/kg/h, meanwhile the dose of remimazolam should be titrated according to RASS scores. Nonbenzodiazepines could be administrated to the patients if sedation targets were not achieved, and the medication and dosage is recorded.

Drug: Remimazolam

Midazolam Group

PLACEBO COMPARATOR

The patients are administered with sedation of midazolam analgesia of remifentanil on the basis of routine treatment. If the patient does not receive sedative drugs before enrollment, patients would be administered with a bolus of midazolam with 0.01-0.05mg/kg intravenously in 1 minute for the first time. And the maintenance dose is 0.02-0.1mg/kg/h, meanwhile the dose of midazolam should be titrated according to RASS scores. Nonbenzodiazepines could be administrated to the patients if sedation targets were not achieved, and the medication and dosage is recorded.

Drug: Midazolam

Interventions

Remimazolam will be diluted with 0.9% saline to ensure that the therapeutic drug and placebo are identical in appearance, and 50 ml syringes will serve as the containers for all intravenous drugs.
