摘要 目的探讨右美托咪啶辅助连续硬膜外麻醉在腹部手术中的疗效观察。方法择期行阑尾切除术的患者60例,连续硬膜外麻醉后随机分为2组,每组30例。A组静脉给予右美托咪啶镇静,B组静脉给予等容量0.9%氯化钠注射液。记录两组患者麻醉期间内脏牵拉反应、寒颤反应、不同时间段的平均动脉压(MAP)、心率(HR)、血氧饱和度(SpO2)、呼吸频率(RR)及警觉/镇静评分(OAA/S)评分。结果与B组比较,A组术中牵拉痛发生率、寒颤发生率明显减少(<0.05);A组患者HR在使用右美托咪啶15min后有一定程度的下降(<0.05)。A组OAA/S评分在用药15min后与术前及同一时间点B组相比均有下降(<0.05)。结论手术开始前经静脉给予一定剂量的右美托咪啶辅助硬膜外麻醉可提供良好的镇静、镇痛效果,减轻硬膜外麻醉下阑尾切除时的牵拉反应和寒颤反应,呼吸抑制轻微,但应加强血流动力学监护。
