Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by Hospira, Inc.:

Primary Outcome Measures:
  • Percent of patients who maintain 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 Outcome Measures:
  • The variations in vital signs (blood pressure and heart rate) in patients from 10 minutes before extubation to 10 minutes after extubation

Estimated Enrollment: 80
Study Start Date: November 2005
Study Completion Date: August 2006
Detailed 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.
