摘　　要：目的 探讨脑电双频指数（BIS）在未插管全麻中麻醉深度监测的应用价值.方法 选择局麻下手术患者60例,随机均分为Ⅰ、Ⅱ、Ⅲ组,分别靶控输注（TCI）丙泊酚1.0、1.5、2.0μg/ml.分别于手术开始前10 min（T0）、局部阻滞麻醉（T1）、手术开始30 min（T2）、手术开始60 min（T3）及手术结束时（T4）记录心率（HR）、平均动脉压（MAP）、血氧饱和度（SpO2）、脑电双频指数（BIS）值和改良清醒镇静（MOAA/S）评分.结果 BIS值随MOAA/S评分下降而下降 Ⅲ组术中各时点的MOAA/S评分均低于Ⅰ组（均P〈0.05）,但术中3例出现呼吸抑制 Ⅱ、Ⅲ组MAP在MOAA/S评分3～2时下降有统计学意义（P〈0.05）.结论 在未插管全麻中,采用丙泊酚1.0～1.5μg/ml TCI镇静较为合适.Objective To investigate the utility of anesthesia depth monitoring of BIS during general anesthesia without tracheal intubation.Methods Sixty patients underwent surgery with local anesthesia were randomly divided into three groups of Ⅰ ,Ⅱand Ⅲ,who were sedated with propofol by TCI propofol 1.0,1.5,2.0μg/ml,respectively.HR,MAP,SpO2 BIS and MOAA/S score were recorded at l0min before operation（T0） .during local anesthesia （ T1） , at 30min after incision （T2） , at 60min after incision （T3） , and the end of operation （T4）.Results BIS values declined with the decrease of MOAA/S.MOAA/S score was lower in group Ⅲ than that in group Ⅰ （all P 〈 0.05）.Respiratory depression was seen in 3 cases in group Ⅲ.The difference of MAP had statistical significance between level 3 and level 2 of MOAA/S in group Ⅱ and group Ⅲ （P 〈 0.05）.Conclusion Propofol 1.0 ～ 1.5 μg/ml given by TCI could produce optimal depth of sedation with less side effects in surgery during local anesthesia.
