摘要 目的探讨选择性β1-受体阻滞剂艾司洛尔对围麻醉诱导气管内插管期间脑电双频指数(BIS)的影响,讨论其对应激反应抑制的机制。方法选择择期手术患者60例,年龄35~55岁,ASAⅠ~Ⅱ级,随机分为艾司洛尔组(A组)和对照组(B组),每组30例。A组麻醉诱导前静脉注射艾司洛尔1mg/kg,然后以200μg·kg-1·min-1的速度泵入,B组在相同时间段给与等量生理盐水。麻醉采用丙泊酚2mg/kg、舒芬太尼0.3μg/kg、罗库溴铵1mg/kg诱导,并记录给予艾司洛尔前(T0)、诱导前(T1)、诱导后(T2)、插管时即刻(T3)、插管后1min(T4)、3min(T5)、5min(T6)的心率(HR)、平均动脉压(MAP)和BIS值。结果 2组患者T0、T1、T2各项指标无统计学差异(P均>0.05);T3、T4、T5各时间点的HR、MAP均升高,但B组患者HR、MAP明显高于A组(P<0.01);T3、T4、T5与插管前相比A组BIS值无明显变化,B组明显升高(P均<0.05)。结论艾司洛尔可以抑制气管内插管刺激引起的BIS值变化,同时通过抑制肾上腺素能作用减轻心血管反应,抑制应激反应。
