Clinical Trial Summary

The purpose of this study is to assess efficacy and safety of dexmedetomidine at the time of extubation and after extubation, in patients requiring postoperative sedation in the ICU.


Description:

The study is to conduct as a phase IV post-marketing clinical study in accordance with the approval condition of dexmedetomidine hydrochloride in Japan. The study will compare the use of dexmedetomidine in patient management at the time of extubation with other sedative/ analgesic management, Comparison is made in the use of dexmedetomidine in patient management between a group in which management is performed with dexmedetomidine and a group in which standard management is performed with propofol in patients requiring postoperative sedation in the ICU The usefulness of dexmedetomidine during postextubation period is also evaluated.

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of patients who maintained a Richmond Agitation-Sedation score =0, -1, -2 Continuously from 1 hour before extubation or end of propofol infusion before extubation, whichever is later, to 1 hour after extubation
Secondary Variations in vital signs (blood pressure and heart rate) in patients From 10 minutes before extubation to 10 minutes after extubation
Secondary Percentage of patients who required analgesia and received supplemental fentanyl before and after extubation From 7 days prior to surgery to the start of surgery, and from the end of surgery to 48 hrs after the start of infusion
Secondary Percentage of patients with a total score of 3 on the Behavioral Pain Scale just before extubation 10±2 minutes before extubation, 2±1 minutes after extubation
Secondary Percentage of patients who required supplemental sedation after extubation After extubation to 24 hours after the start of study drug infusion.
Secondary Percentage of patients who require post-extubation analgesia and who received supplemental fentanyl after extubation After extubation to 24 hours after the start of study drug infusion.
Secondary Amount of supplemental fentanyl required after extubation After extubation to 24 hours after the start of study drug infusion.
Secondary Ratio of time with a Richmond Agitation-Sedation score =+1 From 1 hour before extubation or the end of propofol infusion before extubation, whichever was later, to 1 hour after extubation
Secondary Distribution of Richmond Agitation-Sedation score most frequently recorded while intubated From the start of study drug administration to 1 hour before the expected time of extubation.
Secondary Ease of patient management on the basis of a questionnaire to physicians and nurses Conducted to the greatest possible extent, at ICU discharge or at 36 hours after the start of drug administration, whichever is earlier (in Part II only).

Secondary Patient self-evaluation of experiences during their stay in the ICU Conducted to the greatest possible extent, at ICU discharge or at 36 hours after the start of drug administration, whichever is earlier (in Part II only).
