摘要目的:观察右美托咪定复合芬太尼预防臂丛神经阻滞止血带反应的效果。方法:选择行单侧上肢手术50例,随机分为观察组和对照组各25例。观察组臂丛神经阻滞完毕后静脉注射芬太尼1μg/kg,右美托咪定静脉泵注0.5μg/kg(10min注完),继以0.5μg/(kg·h)维持泵注;对照组臂丛神经阻滞完毕后不给予任何药物。比较两组止血带充气前(t1)、止血带充气后30min(t2)、60min(t3)时的收缩压(SBP)、舒张压(DBP)、心率(HR)、血氧饱和度(SO2)水平变化及镇静、止血带反应发生情况。结果:t1时,两组SBP、DBP、HR、SO2水平比较,均差异不显著(P>0.05);t2、t3时,观察组SBP、DBP、HR水平显著低于对照组(P<0.05);两组SO2水平比较,差异不显著(P>0.05)。t1时,两组Ramsay镇静评分比较,差异不显著(P>0.05);观察组t2、t3时Ramsay镇静评分显著高于对照组(P<0.05)。观察组发生轻度止血带反应2例(8.0%);对照组轻度止血带反应12例(48.0%),重度3例(12.0%)。观察组止血带反应发生率非常显著低于对照组(P<0.01)。结论:右美托咪定复合芬太尼用于上肢手术臂丛神经阻滞可有效减少止血带反应的发生,提高臂丛神经阻滞麻醉质量。
