目的 观察无痛气管镜检查中应用阿芬太尼或舒芬太尼复合丙泊酚的麻醉效果比较。方法 选取2021年3月—2021年7月期间行无痛气管镜检查的患者80例。按照随机数字表法分为对照组与观察组各40例。分别采用舒芬太尼（0.2 μg/kg）和阿芬太尼（20 μg/kg）全麻诱导,记录两组患者麻醉诱导前,诱导后3 min以及检查结束时平均动脉血压,苏醒时间,定向力恢复时间,呼吸抑制,呛咳等不良反应。结果 与对照组比较,观察组麻醉诱导后3 min及检查结束时平均血压下降幅度明显低于对照组,差异具有统计学意义（P<0.05）。观察组的苏醒以及定向力恢复时间都显著小于对照组（P<0.05）。结论 无痛气管镜检查采用阿芬太尼复合丙泊酚麻醉,苏醒时间快,血流动力学更平稳,定向力恢复时间短。

Objective To observe and compare the anesthesia effects of alfentanil and sufentanil combined with propofol in painless bronchoscopy. Methods A total of 80 patients who underwent painless bronchoscopy from March 2021 to July 2021 were selected. According to random number table method, they were divided into a control group and an observation group, 40 cases in each group. Sufentanil was used in the control group （0.2 μg/kg）, and at alfentanil in the control group （20 μg/kg）. Mean blood pressure （before induction of anesthesia, 3 min after induction, and the end of the examination）, wake-up time, orientation recovery time, respiratory depression, coughing and other adverse reactions were recorded in the two groups. Results The mean blood pressure levels of the observation group 3 min after induction and after examination in the observation group declined less than those in the control group （P<0.05）. The wake-up time and orientation recovery time of the observation group were shorter than those of the control group （P<0.05）. Conclusion Painless bronchoscopy using alfentanil combined with propofol anesthesia results in quick recovery time, stable hemodynamics, and short recovery time for orientation.
