Abstract
Objective: To study the changes of correlation between index of consciousness (IoC) and bispectral index (BIS) during target-controlled infusion of propofol. Methods: IoC and BIS of 35 patients undering laparoscopic cholecystectomy under general anesthesia were monitored simultaneously. Anesthesia was induced with TCI propofol. When the plasma propofol concentration increased from 1.5 μg/ml to 4μg/ml, The changes and corredation of IoC and BIS were compared in basic state at the, loss and recovery of consciousness and during intubation. Result: There was no significant difference in basic IoC and BIS (P > 0.05). When patients were at the loss and recovery of consciousness, the IoC and BIS were lower than the basic value (P <0.05). When patients lost of consciousness IoC was lower than BIS, but higher when consciousness recovered(P<0.05). With the increase of plasma concentration of propofol, BIS and IoC declined rapidly. However there was no significant decline of IoC when the plasma concentration of propofol approached 4 μg/ml. And there was significant difference comparinge with BIS (P<0.05). BIS and loC had a significant correlation. During intubation IoC was higher than before intubation and higher than concurrent higher than concurrent BIS (P < 0.05). Conclusion: IoC can reflect the level of consciousness accurately during target-controlled infusion of propofol. IoC has a good correlation with BIS , and can reflect noxious stimulation on EEG in real time.关键词
