摘　　要：目的观察小儿斜视手术七氟醚麻醉下拔除喉罩的最佳脑电双频指数（BIS）。方法择期行斜视手术患儿120例依据拔除喉罩时的BIS范围随机均分为三组：Ⅰ组，75≤BIS〈85；Ⅱ组，65≤BIS〈75；Ⅲ组，55≤BIS〈65。三组均采用七氟醚吸入全麻。记录患儿拔除时血流动力学变化、呼气末七氟醚浓度（CETSev）、PETCO2及并发症。结果Ⅲ组拔除喉罩时喉痉挛、低氧血症、咳嗽、屏气的发生率均明显低于Ⅰ、Ⅱ组（P〈O．05）。结论小儿斜视手术七氟醚麻醉拔除喉罩的最佳BIS为55～65。Objective To observe the optimal bispectral index （BIS） window during laryngeal mask airway （IRMA） extubation in pediatric patients undergoing strabismus surgeries under sevoflurane anesthesia. Methods One hundred and twenty pediatric patients undergoing strabismus surgeries were randomly divided into three groups following the BIS values during extubation with 40 each： group Ⅰ, 75 ≤ BIS 〈 85; groupⅡ , 65 ≤ BIS 〈 75; and group Ⅲ, 55 ≤ BIS 〈 65. The recorded parameters included hemodynamic data, end-tidal sevoflurane and carbon dioxide, and airway complication. Results Patients in the group Ⅲ experienced the fewest events such as bronchospasm, hypoxemia, cough and breathless than the other two groups （P〈0.05）. Conclusion The optimal BIS window during LMA extubation in pediatric patients undergoing strabismus surgeries under sevoflurane anesthesia is 55 65.
