摘要 目的观察右美托咪定在腰麻患者髋及下肢手术中镇静的效果。方法将45例髋及下肢手术,ASAI~Ⅱ级患者分成3组,各15例。A组予右美托咪定0.5 g/kg,B组予右美托咪定0.8 g/kg,两组给药时间均>5 min;对照组予芬太尼1~1.5 g/kg十咪唑安定0.04 mg/kg。监测注药前(T0)与注药后5(T1)、15(T2),30(T3)、60(T4)、120(T5)min警觉/镇静评分(OAA/S)、平均动脉压(MAP)、心率(HR)及脉搏血氧饱和度(SpO2)的变化情况。术后24 h随访患者用药后至结束手术前对有关操作的遗忘程度。结果 A、B组和对照组的镇静评分在T1~T4时间点明显低于T0(均<0.05),3组在各时间点的镇静评分差异均无统计学意义。A、B组MAP、HR下降,与T0差异有统计学意义(均<0.05),在T2~T3与对照组比较,MAP、HR差异均有统计学意义(均<0.05)。A、B组SpO2的下降与T0比较,差异无统计学意义(均>0.05),对照组在T2~T3时间点呼吸抑制比较明显(均<0.05),A、B组与对照组SpO2在T2~T3时间点差异均有统计学意义(均<0.05)。术后24 h随访,A、B组和对照组顺行性遗忘程度差异无统计学意义。结论小剂量右美托咪定不良反应少,能达到镇静效果,是髋及下肢手术行腰麻时很好的辅助用药。
