摘要 目的评价右美托咪啶联合瑞芬太尼在经鼻清醒气管内插管中的可行性。方法选择张口困难的口腔颌面部择期手术患者44例,ASAⅠ或Ⅱ级,随机分为A组(表麻+咪达唑仑+瑞芬太尼组)和B组(表麻+右美托咪啶+瑞芬太尼组),A组患者静脉注射咪达唑仑0.05 mg.kg-1,同时经静脉注射瑞芬太尼0.1μg.kg-1负荷量,然后以3μg.kg-1.h-1的速度泵入瑞芬太尼;B组患者静脉泵入右美托咪啶1μg.kg-1,继而以0.2μg.kg-1.h-1维持,右美托咪啶负荷量输注完后即经静脉注射瑞芬太尼0.1μg.kg-1负荷量,然后以3μg.kg-1.h-1的速度泵入瑞芬太尼。两组患者在瑞芬太尼开始泵入即用1%丁卡因对鼻腔深部、舌根部、咽喉部及声门上进行表面麻醉,再行环甲膜穿刺,以2%利多卡因进行气管内表面麻醉。记录患者表麻前、插管前、插管成功即时,插管后1,3,5 min各时间点的心率,、血氧饱和度(SO2)、平均动脉压(MAP)指标,插管前后Ramsay评分;观察患者气管插管舒适程度。结果在清醒气管插管前后,B组循环变化明显小于A组,镇静程度及舒适度B组也明显优于A组。结论右美托咪啶联合瑞芬太尼可使患者较舒适地耐受经鼻清醒气管内插管。
