Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Mechanically ventilated patients with aged 18 or over and they needed bronchoscopic examination in the ICU were eligible for this study.

Exclusion criteria

  • patients with pacemaker, neuromuscular blockades, propofol allergy or hearing impairment.

Treatment and study plan

AEP monitor

Device

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.

Ramsay Sedation Scale

Procedure

During bronchoscopy, nurses adjusted propofol dose according to Ramsay Sedation Scale.

Primary outcomes

  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 outcomes

  1. mean propofol dose use during examination, times of propofol dose adjustment

    Time frame: 40 minutes
