Abstract:
40), the values of BIS, electromyogram (EMG), signal quality index (SQI), mean arterial pressure(MAP), and heart rate(HR) were recorded every minute for 5min, then additional vecuronium (0.05mg/kg) was administered, and the values of the parameters above mentioned were registered for the next 10min. Results BIS value decreased significantly 3 min after the administration of the additional vecuronium (P0.05). Conclusion A misleading BIS value may be caused by the decline of muscle relaxant during the maintenance stage of propofol/fentanyl anesthesia, which greatly influence the accuracy of BIS monitoring.
