Clinical Trial Summary

It is well known that ICU patients need sedation. Now no ideal sedation drug existed and every sedation drug has its advantage and disadvantage,so combined sedation may use the advantage and avoid the disadvantage of the sedation drug according to the patients'condition. Until now, there is rare study about the combined sedation or sequenced sedation of different sedation drug.The purpose of the study is to explore the value of combined sedation with midazolam and dexmedetomidine compared to single drug sedation in ICU, so as to seek an ideal sedation protocol that could reduce the cost of treatment,obtain the appropriate sedation not under sedation or over sedation,reduce the incidence of delirium, reduce the adverse event of sedation.

Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Related Conditions & MeSH terms

• Delirium

Intervention

Drug:
• midazolam
If the target sedation level is not obtained using the above recommended dosage, midazolam 0.01-0.05 mg/kg is added every 10-15min, until the target sedation level is obtained. If it is over sedation (RASS -3 to -5), and reduction of the dosage of the sedation drug could not ease the situation, and then stop the sedation until the target sedation level is obtained.
• Dexmedetomidine
If the target sedation level is not obtained using the above recommended dosage, midazolam 0.01-0.05 mg/kg is added every 10-15min, until the target sedation level is obtained. If it is over sedation (RASS -3 to -5), and reduction of the dosage of the sedation drug could not ease the situation, and then stop the sedation until the target sedation level is obtained.
• Fentanyl
Fentanyl is used as analgesic drug in order to obtain the VAS <3.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The total time within target sedation level	Sedation level with RASS score is recorded every 4 hours during sedation.; When target sedation was not obtained, sedation drug dosage changed and when adverse event needed to be treated, the sedation level is also recorded.; The adjustment of sedation drug is recorded.	From sedation drug is used to weaning from sedation up to 28 days.	No
Secondary	The dosage of sedation/analgesic drug	Record the induced and maintained dosage of sedation/opioid analgesic drug. The total dosage of sedation/opioid analgesic drug. The added dosage of midazolam.	From sedation/analgesic drug is used to weaning from sedation/analgesic up to 28 days.	No
Secondary	Duration of mechanical ventilation	The duration of mechanical ventilation is recorded.	From beginning to weaning from ventilation up to 28 days..	No
Secondary	Economic outcome	The cost of sedation drug used is recorded. The cost of mechanical ventilation is recorded. The cost of ICU residency is recorded.	From admitted to ICU until ventilation and sedation stopped and participants discharged from ICU up to 28 days.	No
Secondary	Satisfactory of patients to ICU stay from admitted until discharged from ICU	Evaluated the satisfactory of patients to ICU. Using scores including 0 to 10. 0 presents extremely dissatisfied and 10 presents extremely satisfied.	Assessed at time of 1 week participants discharged from ICU.	No
Secondary	Delirium	Delirium is evaluated when daily sedation interruption is done during sedation. Delirium incidence is recorded using CAM-ICU. Treatment of delirium is recorded including drug,dosage and method of administration.	From sedation drug is used to weaning from sedation, up to 28 days.	Yes
Secondary	Vital signs	Heart rate(HR),main arterial pressure(MAP),respiratory rate(RR),pulse saturate of oxygen(SPO2) are recorded every 4 hours. When sedation drug dosage changed and adverse events treated,the vital signs is also recorded.; Gas blood analysis index is recorded when the daily interruption is done and when the SPO2 is less 90% or 10% decrease than normal.	From sedation drug is used to weaning from sedation, up to 28 days.	Yes
Secondary	Duration of ICU stay	Record when participants discharged form ICU.	From date of admission until participants discharged from ICU up to 28 days.	No
