摘要 目的探讨瑞芬太尼复合咪达唑仑用于纤维支气管镜经鼻清醒插管(ANFI)的临床合适靶控浓度。方法将30例拟择期行颈椎非肿瘤手术且颈椎不宜过伸的患者(年龄20~65岁)随机分为L组及H组,各15例。两组均于瑞芬太尼复合咪达唑仑麻醉下由同一熟练的麻醉医生行ANFI,插管过程中L组瑞芬太尼靶控浓度为1ng/mL,H组为3 ng/mL。观察两组插管期间血流动力学变化,行动脉血气分析,评估插管过程中警觉/镇静评分(OAA/S评分)及气管内插管条件,术后随访术中知晓情况及舒适度。结果两组插管过程中HR、MAP、SpO2等与插管前比较无统计学意义;插管过程中H组最低呼吸频率明显低于L组(P<0.05),H组PaCO2明显高于L组(P<0.05)。OAA/S评分总分从基线20分降到最低为10分,瑞芬太尼给药8~10 min达到最深镇静状态。插管过程中,两组下颌松弛度、声带运动和肢体运动情况相近,但气管内插管时L组呛咳发生率高于H组(P<0.05)。H组术中知晓VAS评分明显低于L组(P<0.05);插管过程中H组有轻微不适(VAS 10~40分)者明显少于L组(P<0.05)。结论行ANFI时瑞芬太尼的最适靶控浓度为3 ng/mL;联合应用咪达唑仑可提高镇静质量。
