摘要 目的探讨右美托咪啶在臂丛神经阻滞的麻醉效果,为临床推广应用提供依据。方法选择我院收治的64例择期行上肢手术患者,随机分成2组各32例。于臂丛神经阻滞10min后,治疗组静脉泵入右美托咪啶,对照组静脉泵入生理盐水。观察并记录2组麻醉前(T0)、臂丛神经阻滞10min后(T1)、静脉给药后10min(T2)、30min(T3)、60min(T4)及手术结束时(T5)平均动脉压(MAP)、心率(HR)和血氧饱和度(SpO2)变化及术中不良反应发生情况。结果 T0~T1时,2组MAP、HR及SpO2比较差异均无统计学意义(P〉0.05);T2~T5时,治疗组MAP分别为(70.4±12.2)mmHg、(68.7±10.4)mmHg、(68.9±13.2)mmHg和(75.6±12.4)mmHg,显著低于对照组(P〈0.05)。与对照组比较,治疗组T2~T5时HR显著降低(65.2±13.1vs 82.4±11.6、62.3±11.6vs84.7±10.2、64.5±10.8vs83.2±13.5和74.2±15.6vs82.5±12.6),差异有统计学意义(P〈0.05)。T0~T5时,2组SpO2比较差异均无统计学意义(P〉0.05)。2组术中、术后均未出现恶心、呕吐等不良反应。结论臂丛神经阻滞辅以右美托咪啶麻醉效果满意,不良反应少,值得临床推广。
