摘要 目的:观测右美托咪啶在小儿人工电子耳蜗植入术中的镇静作用及预防麻醉后即时并发症效果。方法:择期行人工电子耳蜗植入术的小儿患者40例,年龄2~5岁,ASAI级,随机分为两组(A组为对照组,B组为右美托咪啶组)。所有患者采取静吸复合全麻,手术结束前30minB组泵入右美托咪啶0.5μg/kg(10min内);A组则泵入等量生理盐水。记录用药前(T0)、用药后即刻(T1)、5min(T2)、10min(T3)、15min(T4)、30min(T5)的心率及平均动脉压的变化。记录术毕至拔管时间、睁眼时间以及躁动评分及恶心、呕吐发生率。结果:与Tn比较,B组T1~T5各时点心率下降(P〈0.05);与A组比较,B组心率在T1、T2、T4时点较低(P〈0.05);两组间各时点平均动脉压差异无统计学意义(P〉0.05)。与A组相比,B组躁动评分与恶心发生率明显降低(P〈0.05)。结论:在小儿人工电子耳蜗植入术毕前应用右美托咪啶.可有效减少术后躁动及恶心发生率.对心率有轻度下降作用.对苏醒与血压无影响。
