老年手术患者静脉应用瑞芬太尼麻醉的临床观察

目的观察持续静脉输注瑞芬太尼在老年手术患者麻醉中的临床效果。方法择期手术的老年患者80例,随机分为瑞芬太尼组和芬太尼组,每组40例。分别采用瑞芬太尼和芬太尼为主诱导和麻醉维持,观察全麻诱导前后、气管插管后、手术开始、手术结束及拔管后的血压、心率及血氧饱和度的变化以及术毕停药后患者自主呼吸恢复、意识恢复及拔管时间,并观察术后不良反应如恶心、呕吐、呼吸抑制及肌僵现象的发生。结果两组患者诱导后血压、心率均低于诱导前（P〈0.05）;瑞芬太尼组患者在气管插管后、切皮时的血压、心率均低于芬太尼组（P〈0.05）;术后自主呼吸恢复、意识恢复、拔管时间及离开恢复室时间也短于芬太尼组（P〈0.05）。结论使用瑞芬太尼麻醉,患者血流动力学更平稳,术后苏醒快,麻醉效果及安全性好,适合用于老年手术麻醉。

Clinical Observation of Continuous Infusion of Remifentanil During General Anesthesia in Gerontal Patients

Objective To observe the clinical effect of continuous infusion of remifentanil during induction of general anesthesia in gerontal patients. Methods Eighty gerontal patients under general anesthesia were randomly divided into remifentanil(R)group and fentanil(F)group(n= 40 in each group).The group R was given remifentanil combined with propofol for the induced anesthesia and maintenance anesthesia,while the F group were given fentanil and propofol in the same way as the group R.Some indices,such as SBP,DBP,...
