【摘要】 目的 通过随机分组的对比观察，评价瑞芬太尼复合异丙酚静脉全麻的临床效果及安全性。方法 50例择期手术患者分为瑞芬太尼组(R组)和芬太尼组(F组)，每组各25例，诱导采用咪唑安定0.04～0.05mg/kg，R组：瑞芬太尼1～2μg/kg，维库溴铵0.1～0.2mg/kg，异丙酚1～2mg/kg。F组：芬太尼2～2.5μg/kg，维库溴铵0.1～0.2mg/kg，异丙酚1～2mg/kg。维持分别为瑞芬太尼10μg/(kg ·h)，异丙酚1～3mg/(kg ·h)泵输维持；芬太尼1μg/(kg·h)，异丙酚1～3mg/(kg·h)泵输。同时吸入66%氧化亚氮和1%异氟醚，MAC保持在0.8～1.5之间。观察的指标有诱导前、插管前、插管期间、切皮前、切皮后5min以及术中每10min的血压、心率变化情况。停药后自主呼吸恢复时间、拔管时间和唤之睁眼时间；自主呼吸的潮气量、频率和ETCO2；拔管后即刻、15min、30min的意识状态(OAAS)和疼痛程度(VAS)；苏醒期间出现寒战、肌颤、恶心、呕吐及躁动等不良反应的情况。结果 与芬太尼相比，瑞芬太尼起效快、清除快、呼吸和意识的恢复优于芬太尼，镇痛效果不弱于芬太尼，安全性与芬太尼相似。结论 瑞芬太尼是一种适合用于持续输注的新型阿片类镇痛药，可用于与异丙酚复合的静脉全麻中。
