Reporting Groups
  Description
BIS-guided Propofol Infusion In the study group, induction was started using alfentanil 4~5μg/kg bolus following repeated propofol boluses (0.5~1.5 mg/kg) until the BIS level reached 70. During maintenance, propofol infusion (3~12 mg/kg/hour) was given using a syringe pump (Injectomat Agilia, Fresenius Kabi, France), which was titrated to keep the BIS level between 65 and 75.
Clinical-judged Midazolam Administration In the control group, induction was started using alfentanil 4~5μg/kg bolus following 2 mg midazolam bolus. After 2 minutes, if the patient was not well sedated, midazolam boluses were repeat by increments of 2 mg/min until conscious sedation was achieved

Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The bronchoscopists were not blinded to sedative procedures. It was difficult to accomplish totally blind conditions. The bronchoscopist would realize which protocol it was when only observing responses of the investigator.
