摘要 目的:研究比较熵指数和脑电双频指数(BIS)监测丙泊酚麻醉深度的差异。方法:选择择期胆囊切除术20例,阶梯式靶控输注丙泊酚,起始浓度1μg/ml,每次升高0.5μg/ml,终浓度4μg/ml,平衡10min后记录各浓度下的RE、SE和BIS。采用丙泊酚靶控浓度4μg/ml、舒芬太尼靶控浓度0.3ng/ml,间断静脉注射维库溴铵维持麻醉,记录不同时间节点的RE、SE和BIS。结果:RE、SE和BIS与丙泊酚靶控浓度的相关系数分别为0.882、0.898和0.919。术中RE、SE和BIS均维持在40左右,停药后,RE、SE和BIS均随意识恢复而升高,切皮刺激可引起BIS显著升高(P<0.05)。结论:RE、SE和BIS均可反映丙泊酚麻醉过程中的麻醉深度,两者差异不显著(P>0.05)。
