目的 评价Narcotrend指数(NI)与七氟醚吸入麻醉患者麻醉深度的相关性,并与BIS值比较.方法 择期手术患者62例,拟于全身麻醉下进行,ASA分级Ⅰ级或Ⅱ级,性别不限,年龄25～60岁,体重44～ 100kg.气管插管后5 min时吸入七氟醚,于呼气末七氟醚浓度(ETsevo) 0.6％、0.9％、1.3％、1.6％、2.1％、2.4％、2.9％、3.2％、3.8％和4.2％时同步记录NI值和BIS值.结果 ETsevo＜2.9％时,其与NI值和BIS值相关系数分别r1=-0.627和r2=-0.669(P＜0.O1)；ETsevo 2.9％～4.2％时,其与NI值和BIS值相关系数分别r3=-0.608和r4=-0.230(P＜0.01).相关系数绝对值比较:r1、r2及r3之间差异无统计学意义(P＞0.05),r1、r2、r3大于r4(P＜0.01).结论 ETsevo4.2％时,NI值能准确反映患者的麻醉深度；ETsevo 2.9％～ 4.2％时,NI值监测麻醉深度的准确性显著优于BIS值.

Objective To evaluate the correlation between Narcotrend index (NI) and the depth of anesthesia during inhalation anesthesia with sevoflurane and compare NI with BIS values in patients.Methods Sixtytwo ASA physical status Ⅰ or Ⅱ patients,aged 25-60 yr,weighing 44-100kg,scheduled for elective surgeries under general anesthesia,were enrolled in the study.Sevoflurane inhalation was started at 5 min after endotracheal intubation.When the end-tidal concentration of sevoflurane (ETsevo) reached 0.6％,0.9％,1.3％,1.6％,2.1％,2.4％,2.9％,3.2％,3.8％ and 4.2％,NI and BIS values were recorded simultaneously.Results The correlation coefficients between ETsevo and NI and BIS values were-0.627 (r1) and-0.669 (r2) respectively when ETsevo ＜ 2.9％,and-0.608 (r3) and-0.230 (r4) respectively when 2.9％ ≤ ETsevo ≤4.2％ (P ＜ 0.01).Comparison of the absolute value of correlation coefficients:no significant difference was found between r1,r2 and r3 (P ＞ 0.05) ; r1,r2 and r3 were significantly greater than r4 (P ＜ 0.01).Conclusion When ETsevo 4.2％,NI values can accurately reflect the depth of anesthesia; when 2.9％ ≤ ETsevo ≤4.2％,the accuracy of NI values in monitoring the depth of anesthesia is superior to that of BIS values.
