Brief Summary:
To compare the difference of sedation monitoring for bronchoscopic examination monitoring by auditory evoked potentials (AEP) or Ramsay Sedation Scale (RSS) in mechanical ventilated patients.

Condition or disease Intervention/treatment
Sedation Method Device: AEP monitor Procedure: Ramsay Sedation Scale

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 37 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Supportive Care
Official Title: Impact of Auditory Evoked Potential Index Monitoring on Bronchoscopic Examination in the Mechanical Ventilated Patients - A Prospective, Randomized, Controlled Study
Study Start Date : March 2007
Primary Completion Date : March 2008
Study Completion Date : March 2008

Arm Intervention/treatment
Experimental: AEP monitoring Device: AEP monitor
In AEP monitoring group, nurses adjusted propofol dose according to AAI values. If AAI>40, titrate up propofol dosage, AAI<25, titrated down propofol dosage.
Active Comparator: RSS monitoring Procedure: Ramsay Sedation Scale
During bronchoscopy, nurses adjusted propofol dose according to Ramsay Sedation Scale.



Primary Outcome Measures :
  1. Change of mean arterial pressure, heart rate and AAI [ Time Frame: 40 minutes ]
    During bronchoscopy, we recorded AAI number, blood pressure and heart rate every 5 minutes, totally up to 40 minutes.


Secondary Outcome Measures :
  1. mean propofol dose use during examination, times of propofol dose adjustment [ Time Frame: 40 minutes ]
