[摘要] 目的 MAC技术下单纯药物(瑞芬太尼)麻醉在无痛结肠镜检查中的有效性及安全性。 方法 方便选取2016年1—12月住院的肠镜预约汉族患者80例列为观察对象，并以随机分配原则分为两组(40例/组)，其中给予丙泊芬麻醉为对照组，在MAC技术下应用瑞芬太尼麻醉为观察组，记录两组患者生命体征监测情况，统计其麻醉效果、药物不良反应及麻醉满意度。结果 术中观察组患者心率、血压等生命体征指标相较于对照组更为平稳(P<0.05)；且观察组镇静Ramsay等级为(2.0±0.5)级明显优于对照组(3.5±0.8)(P<0.05)，同时在两组不良反应发生率比较中观察组为7.50%明显低于对照组的75.00%，差异有统计学意义(P<0.05)。结论 MAC技术下单纯药物(瑞芬太尼)麻醉应用于无痛结肠镜检查麻醉效果可靠，且不良反应更少而用药安全性更高，值得推广应用。

    [Abstract] Objective To study the efficacy and safety of simple drugs (remifentanil) anesthesia in the diagnosis and treatment of colonoscopy. Methods 80 cases of colonoscopy were divided into two groups (40 cases / group) according to the principle of random distribution. The patients were given propofol Anesthesia was used as the control group. The patients were treated with remifentanil anesthesia as the observation group. The vital signs were recorded and the anesthesia effect ......
