Sedation by Dexmedetomidine and Propofol

September 12, 2017 updated by: Hyo-Seok Na, Seoul National University Bundang Hospital

Comparison of the Upper Airway Patency by Dexmedetomidine and Propofol Used for Sedation

Under the hypothesis that dexmedetomidine sedation would result in less upper airway obstruction, we evaluated the occurrence of upper airway collapse or the requirement of airway intervention in patients with obstructive sleep apnea during dexmedetomidine or propofol sedation.

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Dexmedetomidine
Intraoperative sedation is performed by using dexmedetomidine.
As a loading dose, 0.5 μg/kg dexmedetomidine was administered over 10 min, which was then administered continuously at a dose of 0.2-0.8 μg/kg/h. Sedation was maintained at modified observer's assessment of alertness/sedation scale 3
Experimental: Propofol
Intraoperative sedation is performed by using propofol
Propofol was infused continuously via a target-controlled infusion device, and the effect-site concentration was maintained with a range of 0.5-2.0 μg/ml. Sedation was maintained at modified observer's assessment of alertness/sedation scale 3

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The occurrence of upper airway obstruction
Time Frame: During the sedation period, an average of 3 hours.
When end-tidal carbon dioxide was not detected in spite of the respiratory effort during the sedation period, the case will be regarded as the occurrence of upper airway obstruction.
During the sedation period, an average of 3 hours.
