简要总结
Evaluate efficacy and safety of dexmedetomidine long term administration in ICU patients who require more than 24 hours sedation.
详细描述
According to the current dexmedetomidine indication, the duration of dexmedetomidine administration is limited within 24 hours. However, there is a strong demand from the medical specialists for continued administration of dexmedetomidine in excess of 24 hours in the medical practice because a large number of patients require sedation for more than 24 hours in ICU. To meet such clinical demand, it was planned to conduct a phase III long-term administration study of dexmedetomidine to obtain the approval on the infusion of dexmedetomidine for more than 24 hours.

结局指标
主要结局
Incidence rate of adverse drug reactions of hypotension, hypertension and bradycardia which correspond to the protocol definitions
时间窗: Prior to study drug infusion, during the study drug infusion and 24 hours after study drug infusion end; maximum ≤28 days.
Definition: * Hypotension: dosing start or dose increase of vasopressor drug or use of fluid bolus ≥500 mL within 1 hour resulting from SBP\<60mmHg, DBP\<40mmHg or ≥50% lower than baseline. * Hypertension: dosing start or dose increase of intravenous anti-hypertensive medication resulting from SBP\>160, DBP\>100 or. ≥50% higher than baseline. * Bradycardia: dosing start or dose increase of positive chronotropic medication or use of pacemaker resulting from heart rate \<40bpm or ≥50% lower than baseline.
