摘要
目的 比较靶控输注异丙酚复合瑞芬太尼麻醉时Narcotrend指数（NI）与BIS监测镇静深度的准确性.方法 择期拟在全麻下行腹部手术患者10例,性别不限,ASA Ⅰ或Ⅱ级,年龄18～56岁,体重52～67kg.麻醉诱导后采用靶控输注异丙酚（Cp 3～μg/ml）和瑞芬太尼（Cp 3～4ng/ml）,间断静脉注射顺阿曲库铵0.05mg/kg维持麻醉,同时监测BIS和NI,每隔1min成对记录二者的监测值,行相关分析和一致性分析.记录镇静深度判断错误次数（Ⅰ型错误：BIS〈40而NI〉62;Ⅱ型错误：BIS〉60而NI〈20）.结果 BIS和NI的相关系数=0.812,Kappa系数=0.513（P〈0.01）.一致性限度（-18.1,6.4）;镇静深度判断错误发生率（0.46±0.39）%,其中Ⅰ型错误发生率（0.15±0.11）%,Ⅱ型错误发生率（0.31±0.26）%.结论 NI监测镇静深度与BIS的一致性尚可,可用于靶控输注异丙酚复合瑞芬太尼麻醉时镇静深度的监测.
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.
