Abstract:
Objective To compare bispectral index (BIS) with narcotrend index (NI) during propofol-remifentanil anesthesia administered by target-controlled infusion (TCI).Methods Ten ASA Ⅰ or Ⅱ pafients aged 18-56 yr weighing 52-67kg undergoing abdominal surgery lasting>1h were included in this study.BIS and NI were monitored simultaneously.Anesthesia was induced with TCI of propofol with target plasma concentration (Cp) of 3～4μg/ml and remifentanil (Cp 3-4ng/ml).Tracheal intubation was facilitated with cis-atracurium 0.3 mg/kg.The patients were mechanically ventilated.PETCO2 was maintained between 30-35 mm Hg.Anesthesia was maintained with TCI of propofol and remifentanil by the anesthesiologist bhnded to BIS and NI values.according to hemedynamic parameters.BIS and narcotrend values were recorded every minute and compared by another anesthesiologist.All data were compared by Bland-Altman analysis and with Kappa coefficient for agreement.The correlation between BIS and NI was tested by Spearman correlation analysis.The number of error ofjudgement (Type Ⅰ was defined as BIS<40 and NI>62;Type Ⅱ was defined as BIS>60 and NI<20)Was counted.Results The correlation and agreement between BIS and NI during maintenance of propofol-remifentanil anesthesia administered by TCI showed good consistency.Conclusion Both NI and BIS Can help anesthesiologist control the depth of anesthesia during TCI of propofol-remifentanil.
