Narcotrend Versus Bispectral Index Monitoring During Sufentanil-Midazolam Anesthesia for Bronchoscopy

This study was aimed to determine whether narcotrend monitoring was better than bispectral index monitoring during sufentanil‐midazolam anesthesia for bronchoscopy under conscious sedation. Patients were randomised to receive Narcotrend, Bispectral Index(BIS) monitoring or without monitoring. Midazolam was given by non‐anaesthetist physicians to achieve moderate levels of sedation as assessed by the narcotrend index (NI; B and C) or bispectral index (BIS; between 70 and 85) or according to patient's tolerance assessed by physician . The primary end‐point was dosage of midazolam. Other end‐points included adverse events, patient tolerance and physician satisfaction.
